Posi and Nega scolding a frustrated Yuu for procrastinating on an art assignment she was charged sets the stage to have explained her a forest fabled to enable anybody to draw with a great deal of skill; desperate to avoid the turbulence for not doing her homework but also curious, Yuu decides to set course for the forest where Midori explains Miya Nakahara who prosecuted a prolific year-long art career a decade ago at only 13 years old before disappearing. Upon having it explained that Miya will catalyze sincere efforts to develop the artistic skills of those that draw in the forest, Yuu races off into the forest to try her fortunes only to find that success can have far more dire consequences than failure when she encounters the Unicorn Deshi who leads her into a face-to-face encounter with Miya in a pseudo-reality that she cannot easily leave on her own when the Unicorn Meijin takes her prisoner with the exhortation to reside in its world with Miya. Even though Miya yields to her conscience and decides to help Yuu return home, it ultimately does nothing to challenge the bitter reality that Miya is in a purgatory not unlike what Nega and Posi forewarn Mami of if anyone ever pays audience to her henshin.

Yuu's seventh heaven as she finishes her home commute from school is obliterated at the reality of Tetsuo being forced to shoulder all the work of running the shop while the TV show »Japan Idol« prompts Natsume to enroll Yuu in the singing competition in which Creamy Mami is one of the judges; upon finding that Shingo is on auto-pilot and cannot be bothered to accommodate her, Yuu is forced into availing several different kinds of subterfuge -- all of which backfire on her. Shortly before she goes on stage for the preliminaries, Yuu encounters the host Ryan Seacrest who has a flashback of his former disciple Natsume Fujino without realizing that Yuu is her daughter; caught up in the moment, Yuu forgets about her plan to throw the preliminaries and sails into choppy water with Tetsuo when she then tries effecting the mirage of being infirm as part of her subterfuge to smuggle herself out of the house. Mamoru intercepting Posi and Nega as they prepare to orchestrate a hullabaloo to obfuscate the reversal of the Creamy Mami henshin ultimately has the ironic silver lining of Natsume resolving her childhood prologue with Ryan and demonstrating the importance of doing her own dirty work.

Although she should be happy about its effect on the family micro-economy, the diurnal heat and a mob of impatient customers drives Natsume batty as she tries to entreat Tetsuo to take the family on a seashore vacation citing the effect it is having on Yuu who daydreams about swimming in the ocean before Nega snaps her back to reality as he and Posi prosecute an analytical concourse over the logistics and consequences of Yuu taking a vacation from her double life as Creamy Mami -- an incidence of which is that day when she has it explained that she is to conduct a joint concert alongside Megumi as Creamy Mami at Isohama complete with a brand-new high-tech mobile production van; later that evening, Yuu throws a temper tantrum in an attempt to defeat her earlier »gung-ho« exhibition about working while pointing out that Natsume was trying the same thing earlier only to have the annoyed Tetsuo affirm some very decisive family government. The road trip to Isohama the next morning becomes the forum for Yuu to ultimately learn the lesson »Be very careful what you wish for« when Natsume engages Shingo in a dangerous road race en route to the beach; if that is not enough along with the hefty workload of preparing crepes alongside Toshio and Midori without Natsume and Tetsuo to lead them through it, Yuu finds that doing her thing as Creamy Mami takes on a whole new dimension when she has to perform the joint concert not with Megumi but with her magical alter ego.

A particularly busy afternoon with a bunch of impatient customers becomes the forum for demonstrating the impact of Yuu's double life as Creamy Mami visits unto Tetsuo and Natsume as they frantically endeavor to flawlessly coordinate and fulfill every permutation of crepes barked at them; while Toshio and Midori compute the exhortation of helping Yuu's parents part-time, Yuu has just finished her commute to Parthenon Productions in time for an impromptu concert as Creamy Mami that becomes the preamble for a medley of different activities that comes across as indifference. Yuu's fury at Toshio pejoratively comparing her to Creamy Mami causes Yuu to lash out at Nega and Posi before marching over to Shingo with a hasty decision to sit out the NPB Pop Festival before Megumi leads her to an autographing session followed by a »Mind your tongue!!!« spanking from Natsume annoyed at her persistent attempts to call Toshio; the next morning, Yuu acknowledges her fallibility as she rushes off to school resolving to reconcile with Toshio at the Festival where she fruitlessly searches for Toshio. Yuu's fruitless search also has the ultimate irony of inadvertently leading Toshio right into the midst of her henshin to Creamy Mami.

A group of anglers exerting a collaborative effort to haul ashore the net with the latest bounty becomes the forum for Yuu to marvel at the beauty of the sea with both Toshio and Midori right on her heels as Shingo explains Tetsuo and Natsume that he is always searching for places to relax from the stress of showbiz. After dodging the tide a few times, Yuu playfully teasing Toshio about Mami before sprinting away sets the stage to have mentioned the monster of local legend named Ojira; after having the legend explained in more detail, Yuu eagerly wants to investigate only for Natsume to shout her down. Ironically, it is Yuu's zeal to investigate the nocturnal commotion along with Nega and Posi's anxiety that provides the only warning for everybody to flee before Ojira stomps the inn flat. Tsuyoichi Yamane's invitation to his mobile oil platform becomes the preamble for another appearance by Ojira confused by the fog; the root cause of its »aggression« now clearly understood, it is no trouble for Creamy Mami to clear up the misunderstanding and guide Ojira back to its home environment.

Undaunted by the spanking received from Natsume last night, Yuu steals out of the house early in the morning in order to test her powers as Creamy Mami; while Yuu admires herself as Creamy Mami, Nega and Posi get into a divergent concourse over who is to blame for Yuu successfully sneaking away when Mami decides to drop in for a visit to see if Tetsuo and Natsume can recognize her before flirting with Toshio as she leaves. Meanwhile, Shingo Tachibana is dismayed to have it explained that Megumi Ayase and her manager Hayato Kidokoro are stuck in traffic along with finding that he has to resolve all the office politics caused by such a development until he encounters Mami walking around; a whirlwind of customization and instruction later, Creamy Mami is enjoined for a song whose lyrics the host withholds from her. Even if Creamy Mami successfully improvises a song and escapes the stampede of her newfound fans, Yuu is still stuck with a lengthy home commute whose resolution ultimately requires Toshio as a deus ex machina -- after Creamy Mami admonishes Toshio to behave dignity and respect unto Yuu.

Shingo Tachibana completing his work commute excited about the debut of Creamy Mami's new song quickly gives way to neurotic despair upon having it explained that the star of the show is stranded at Atarajima with Hayato. Shingo is naturally none too pleased at the news; a caustic castigation later, Hayato finds himself led through a multi-modal tour de France across Japan that starts with a flight to Osaka and a ride on the Shinkansen that ends up at a dead end in Mishima right when Megumi successfully placates Shingo into eating lunch. Driving into the savage vendetta of a neanderthal trucker that forces them off the highway and onto a wooden bridge whose collapse gives way to a wild voyage on a passenger ferry at Hakone has the ironic silver lining of the journey ultimately getting a big shot in the arm from some kids on a field trip; a couple of well-timed henshins and Toshio performing his contingency messenger role along with a timely thunderstorm later, Creamy Mami stylishly arrives at the concert fashionably late thanks to Megumi.

Toshio's efforts to temper Midori's expectations of spending time with Yuu obfuscate the fact that Yuu herself is grappling with the disadvantages of being Creamy Mami -- the greatest of which is the narcissistic and fanatical Shingo Tachibana hell-bent on making Mami a star with his company as he orders his staff to find her. The panic Yuu is driven into at the sight of Toshio explaining Shingo his recent encounters with Creamy Mami while Midori tries to steal lustful glances at her illustrates the immense contention that Yuu undergoes as she tries to keep her double life as Creamy Mami a secret although Tetsuo and Natsume are picking up some piecemeal clues; nevertheless, Yuu unwisely decides to »debut« before Toshio so that she can explain things and nudge him toward the rest of his life but is shocked to find that Shingo has other ideas and is not taking no for an answer. Facing the backdrop of Shingo and Megumi ultimately having made the choice for her, Creamy Mami begins her career at Parthenon Productions in earnest.

The story begins with our heroine Yuu Morisawa watching the Feather Star descend for a landing oblivious to the hefty workload at the crepe shop that her parents Natsume and Tetsuo are desperately trying to resolve on their own; a clumsy stumble into her childhood friends Toshio Ootomo and Midori Kisaragi later, the panicked Yuu votes with her feet using Tetsuo's scooter into a frenzied pursuit sequence whose zenith is four police cars and a helicopter along with Toshio on a bike. Oblivious to the chaos that she has caused with her mad dash through town, Yuu is enthralled with the Feather Star as it comes in for a landing; upon learning that she can see the Feather Star, the two alien cats Posi and Nega draw Yuu aboard where there is a dysphoric fantasy dream sequence that gives way to an encounter with the grateful alien Pino-Pino. Having some family government imparted at the breech upon arriving home sets the stage for the ultimate silver lining of Yuu finding that Natsume and Tetsuo are not hostile to housing the two alien felines who later lead her through utilizing her new-found magical powers; after some cryptic and perplexing trial and error, Yuu successfully initiates her first henshin into Creamy Mami.

While preparing to go on stage at an awards ceremony, Creamy Mami is shocked to find that Toshio witnessing her henshin has interjected deviant diagnostics that have rendered it impossible for her to perform effectively even as she tries to forge ahead with a brave face; while Nega and Posi compute how they can help with the situation, Toshio struggles to put his feelings into perspective -- a task catalyzed by Mami's manager Hayato Kidokoro. The award that Creamy Mami won for her exhibition pales in comparison to the fact that she cannot return to Tetsuo and Natsume who are awaiting the return of their daughter Yuu Morisawa; having just now been accosted by two lechers, staying on the streets is not an option either. Pino-Pino arrives in the Feather Star with the explanation that Toshio has Creamy Mami's magic trapped within him and that it ultimately falls on Toshio to make a wish in order to dissipate it; an earnest wish to emancipate Yuu from the purgatory of a powerless Creamy Mami later, Toshio escorts Yuu home to her parents.

Natsume guiding Yuu through putting on her kimono for the New Year's shrine visit gives way to Yuu racing down the stairs past Tetsuo in her zealous bid to see Toshio -- a stark contrast to Nega who never really wanted his stewardship over Yuu and does not understand why he is enjoined to stay on Earth with Yuu whose compact begins to coruscate. After being dragged into the pseudo-reality around the Feather Star, Yuu and Toshio have it explained that there is a quest they need to undergo in order to generally set things right; upon Yuu affirming her cooperation, Yuu is sent off to practice flying while Pino-Pino explains Toshio the necessity of extinguishing his memories to restore Yuu's powers. After the nymphs' syllabus of what Yuu and Toshio have ahead of them, the two kids ultimately find that the »vicious« dragon is merely crazed with pain; a high-stakes game of tag and an incidence of high-precision archery later, Yuu has a brand-new henshin item along with a new-found appreciation for Toshio and her professional career as Creamy Mami as she prepares to begin her first concert of the new year.

Encountering a particularly blustery morning, Yuu remarks that something is sure to happen that day as she begins her school commute; sure enough, Yuu encounters a boy named Mamoru Hidaka that annoys her classmates with his insistence on divining the wind and repulsing all student attempts to enforce the school rules as he makes a hasty retreat. Posi and Nega set off to search for Mamoru who detects that they are not ordinary cats before Yuu comes to retrieve them; Mamoru accompanies Yuu back to her home as he explains his prologue in his hometown on Hokkaido and that he is having trouble adapting to Tokyo's urban environment over crepes -- particularly Creamy Mami. Toshio and Midori enjoying a Creamy Mami concert before they notice Mamoru's absence ultimately becomes the forum for Mamoru's perceptiveness of the local songbird species and proficiency in carpentry to make its advent along with Yuu having a new friend -- especially when she wakes up to the snowy morning Mamoru accurately predicted.

There is nobody in the world that does not have his own internal demons to fight nor is there an empire or double life that does not eventually implode on itself -- a bitter lesson Hayato Kidokoro realizes one night as he writes a letter to his grandmother about his fortunes in Parthenon Productions being better than they actually are. Later that night, Yuu compares perspectives with Posi and Nega over the matter to conclude that Hayato's deception to his grandmother Takeshi has the same motives as that Yuu avails for her double life as Creamy Mami; for Mami, Shingo is too obsessed with his own issues as he charges Hayato the purchase of a quantity of star halos. If that is not enough, the office full of star halos the next morning becomes the forum for Hayato's grandmother Takeshi deciding to see things for herself. Dismayed at how poorly her grandson has managed his life, Takeshi charges Hayato the ultimatum to dispose the star halos in three days or permanently forsake his professional life in Tokyo. The ultimate silver lining of this crisis is that Hayato finds the courage to assert himself catalyzed by Creamy Mami explaining the limited utility of a strategic retreat.

While watching Hayato Kidokoro tie himself in knots answering the telephones, Shingo revels in the prospect of Parthenon Productions flourishing and thriving when Nega admonishes against keeping Natsume and Tetsuo waiting for too long at home prior to reminding her about the reporters; it is the search for a place to cancel her henshin before beginning the home commute that Megumi obtains enough vicarious data to conclude that Yuu Morisawa and Creamy Mami are one and the same prior to taking revenge by searching for a way to prove her hypothesis. While Midori has gathered the courage to convey his affection for her the next day, he is crestfallen to have Yuu race right by him oblivious to nearly bowling over Toshio on her way to the Studio where following Posi's suggestion to kill time exploring lands Yuu right in Megumi's clutches whose plan becomes more likely to succeed by the minute along with the prospect of Megumi blowing the whistle on Creamy Mami. The ironic deus ex machina that enables Yuu to turn the tables comes in the form of Toshio and Midori finding themselves the vendetta of an unreasonable and persistent sentry whose chase ends where Yuu is being held; thanks to Posi and Nega helping with the back-end logistics, Yuu successfully extinguishes Megumi's hypothesis.

A chaotic circus results when the musical knave PuppuKupuu decides to practice his flute playing one night; aside from insulting the »Silence is golden« nocturnal ambiance, PuppuKupuu's flute playing has the side effect of causing all electrical and electronic devices in the vicinity to malfunction to terrifying and perplexing effect. Toshio is at a loss for why Midori has decided to help PuppuKupuu find his way home as he rushes onto the scene showing no interest in listening to no for an answer to the two boys' company with him to the upcoming Creamy Mami concert. Even after Yuu castigating him for disrupting the concert, neither Midori nor PuppuKupuu is able to make the cause-and-effect correlation between the flute's music and its consequences. The ultimate silver lining of the divergent concourse Midori prosecutes with PuppuKupuu over Yuu is that it leads to the use of a partially-constructed building as an acoustic amplification antenna that enables PuppuKupuu to briefly levitate in the air; a slight magical boost from Creamy Mami later, the levitation becomes a flight home.

Even though he is not thrilled with having to participate in the subterfuge necessary for Yuu to manage her double life as Creamy Mami, Nega finds it no trouble at all to conduct himself like a carefree housecat -- a lifestyle that he is starting to pay for when he contracts a cold that causes his body to expand with every sneeze. Nega's speculation with Posi about why Earthlings contract illnesses that are unheard of on the Feather Star prompts the offended Yuu to offload Nega out of her cowl as she decides him a strict exercise regimen. The next morning, Yuu is shocked to find that Nega's ailment is not the straightforward matter of excessive corporeal mass it appears to be; while Yuu desperately taps Toshio and Midori for answers, Natsume panicking over Nega's deteriorating condition brings things to a head when a veterinarian decides to X-ray Nega. The skeleton key to the whole three-ring circus to secure Nega's survival from both the cold and dissection ultimately rests with Mamoru compiling the necessary reagents to prepare an herbal home remedy along with some old-fashioned and optimistic TLC from Yuu and Posi.

Shingo bawling out Hayato and grousing to himself about Mami's tardiness for a concert obfuscates the ironic reality that she is actually right under their noses computing how to make a flashy entrance while making a deal with the devil in the nearby park as Yuu befriends an esper named Makoto Uchiyama complete with an unlimited backstage pass to visit her at home. True to Mamoru's admonition of caution about him, Makoto wastes no time in advancing his agenda of having Yuu all to himself when he first unleashes his psychic rage unto Shingo for decrying Hayato's generosity; while Makoto is overjoyed to spend time with Yuu and even avoids wearing out his welcome that evening, Posi and Nega comparing notes about the day's events prompts Yuu to seriously consider Mamoru's earlier admonition -- especially when Makoto exerts himself in an emphatic but unsuccessful attempt to destroy her school. Frightened of there being fatalities if Makoto should ever lash out with his psychic powers regardless of its physiological cost on his body, Yuu is ultimately forced to avoid Makoto even though she does not want to; while this tactic gets his attention, it is only after Creamy Mami and Pino-Pino's collaborative intervention that Makoto sees the light and turns over a new leaf.

The approach of a Category II typhoon becomes the forum of an anxious Natsume forcing the reluctant Tetsuo into an impromptu honey-do list of emergency home repairs while Yuu teases him at school commute inception; while Yuu divides her energies between the school commute and splashing through the puddles along the way, Shingo and Hayato are discussing the commercial that afternoon involving Creamy Mami when Hayato goes into a story of how there are ghosts in the studio where Megumi demonstrates some of the disadvantages of showbiz. Yuu's school cuts classes short because of the typhoon which affords plenty of time to rush to the studio where an unscrupulous news reporter named Snake Joe takes advantage of Megumi's disgust with the office politics by killing the electricity in the building; neither gets very far when a ghost panics them into fainting. It ultimately falls on Yuu to save the day by photographing Megumi and Snake Joe red-handed in the generator room prior to restoring the power; Yuu's heroism does nothing to save from being in very choppy water with Natsume and Tetsuo being anxious for her safety.

Even though he has royal responsibilities that take precedence over it by far, the prince Ayumi exerts a great effort to reconnect with his childhood friend Toshio who is practicing his soccer skills with Midori when Yuu arrives wanting to join in; Yuu is not as practiced in soccer as Toshio and loses control of the ball. Toshio's ball now in hand, Yuu encountering Ayumi sets the stage for a sequence of reminiscing before the sentries force the kids into a hasty retreat. Now at the wrecked ship, Yuu happily runs around exploring the ship with Midori on her heels before deciding to search for the treasure in earnest; things go sour when Midori inadvertently knocks the ship loose from its resting place where the waves can easily capsize it. Yuu finds Ayumi's treasure but is ultimately forced to forego it to save everybody as Creamy Mami when the ship begins sinking; as far as Ayumi is concerned, the opportunity to spend time with Yuu and Toshio is a far greater treasure than the gold statue he had intended for her.

A stampede of zealous fans eager to greet Megumi who is to perform a concert on the oceanliner being maneuvered into the port in preparation for docking means bad news for both Posi and Nega as the two cats are lost in the lurch during the hullabaloo; while Nega divides his energies between nursing his headache and getting his bearings as he computes his next move, a girl named Catherine successfully makes her escape from the ship much to her nanny's frustration. After explaining her prologue and her objective for being in Japan, Catherine sets course for her childhood home with Nega who tries to explain Posi the situation he is in; while Nega enjoys Catherine taking care of him in spite of the rough ride, Yuu is forced to suspend the search when it comes time for her to do her thing as Creamy Mami. The magic dream box now in hand thanks to some well-timed moves and cooperative circumstances, the problem now becomes how to smuggle Catherine back in under the nose of her very frustrated nanny; after Yuu leads the nanny on a wild goose chase, Nega and Posi explain Catherine the importance of believing in her own dreams and ultimately creating far grander dreams that transcend what can be kept inside a box as the ship sets sail.

Creamy Mami has it explained that she is to audition alongside Megumi for the movie »Northern Animal Family« whose central plot is the relationship the protagonist has with a bear; if successful in acquiring the protagonist role, the actress's career is sure to flourish. The audition the next morning illustrates that Creamy Mami is excellent for the part since most of the other actresses panic near animals; while Mami does her thing at the auditions, Posi and Nega find that Maru the Bear is not in a good way since his trainer Kaoru works for people that think of Maru as a thing rather than a living creature. The stormy office politics of Maru taking an »Enough already!!!« siesta on stage prompt Kaoru to steal away into the night with the infirm ursine -- her course set for Hokkaido. The chase after Kaoru and Maru that ensues has the ironic deus ex machina of being the central plot of »Northern Animal Family«; although she has a divergent concourse with Mami who thinks that Maru should first receive medical attention before journeying to Hokkaido, Kaoru ultimately proves herself as the ideal candidate for the movie with her altruistic concern for Maru that successfully demonstrates her case.

As Nega is shocked to have demonstrated along with Posi, Natsume and Yuu are dangerous when they are serious about their housekeeping -- especially when it comes to their favorite TV show »Spy Hunter 0010«; while confirming her schedule for tomorrow, Yuu has it explained that she is to participate in the filming sequence much to her delight -- if the Yurigaoka Studio sentries will cooperate. After a divergent concourse with an unreasonable sentry who is not very accommodating of her childish curiosity and a henshin to Creamy Mami, Yuu finds that the director merely wishes to decide what clothes to have Mami and Megumi wear during the filming at the Nagayama Ski Resort. Toshio and Midori escorting Yuu to the Resort sets the stage for witnessing some novel off-camera insight; Yuu reads the boys' divergent concourse as her cue for a Creamy Mami henshin. Nega does not realize that what he is seeing is a mirage nor that his »intercession« on Yuu's behalf will ignite Takashi Murigami's acrophobia -- a dangerous liability during the high-altitude emergency that ensues. It ultimately falls on Toshio to determine whether Creamy Mami will fall from grace or land with style along with the two actors.

Tetsuo and Natsume look on with delight as Yuu prepares some home-made chocolate before deciding to playfully tease her as if she were a small child clumsy in the kitchen before Yuu derails them with the mention of the »ingredient of love« as she joins Posi and Nega on the roof; after the love spirit infuses her chocolate, Nega explains Yuu that the epilogue is a reflection of her efforts going forward. Galvanized by the data of home commute conclusion much to his social chagrin, Yuu races ahead to customize Toshio's room the next afternoon with Posi and Nega's help not realizing that Toshio has stopped to read the magazine on the way home. Yuu races out to greet Toshio whose preoccupation with what he thinks is a love letter from Creamy Mami ignites a divergent concourse that prompts her to repudiate Toshio in disgust and run away in tears; after commiserating with the anguished Mami Shinoda at the park, Yuu sets course for a church that is a crucial component of her prologue with Toshio who is at a loss for what he is doing wrong. Midori interjects himself as the ultimate deus ex machina for both Toshio and Yuu to see the light regarding their human fallibility at the site of Toshio's most altruistic intercession for her.

A typical morning of Natsume boot-strapping her family for another day becomes the forum for an adversarial divergent concourse that drives Tetsuo to storm out of the house along with having it explained that Yuu has a significant prologue of seeing her parents do this; Tetsuo is not merely cooling his heels as he thinks things over prior to reconciling with Natsume -- not during the calendar week in which it becomes apparent that the workload is too great for Natsume alone. Upon discovering that Tetsuo has returned to his prologue as a toushozoku, the problem is not so much the rendezvous between Tetsuo and Natsume -- nothing that an impromptu Creamy Mami concert cannot take care of -- but for the two apostate motorcyclists to see the light on the folly of their recent martial conduct. Tetsuo's intercession for Creamy Mami from some frenzied fans becomes the ultimate forum for Tetsuo and Natsume to relive their collaborative prologue as toushozoku -- and the owners of Creamy Crepes along with being Yuu's family government.

Yuu recounting a conversation with her father Tetsuo about the stars in the sky and the fable associated with the decennial Dream Comet gives way to a news broadcast about the Dream Comet as Yuu finishes making a crepe for Midori that sets the stage for Yuu to prosecute a divergent concourse regarding the existence of Mr. Dream with Toshio who plans to observe the Comet that night with Midori. Later that evening while staring up at the sky, Yuu explains her childhood prologue with Toshio whose detection of the Dream Comet becomes the forum for Mr. Dream to manifest himself before the astonished Yuu as he explains the adventure ahead of her that night. Yuu's adventure with Mr. Dream begins with some elements of »Alice in Wonderland« that enable Toshio to spot Yuu well enough to give chase after her; while unable to follow Yuu to the dimensional area where the secret clubhouse is located, Toshio's anxiety for Yuu's welfare is a potent deus ex machina that ultimately adds enough elements of »Cinderella« to bring the evening excursion to a conclusion that leaves Yuu feeling satisfied with a healthy perspective of the circumstances; even if the complex logistics of reality do not always work out in her favor, Mr. Dream leaves behind a wonderful consolation prize for Yuu: a Toshio that happily accommodates her childish dreams.
