Under Haruka's control, Hibari knocks out Kiriya and steals the Yang scroll. The next day, Haruka appears before Hibari and retrieves the scroll from her, saying she will most likely be labelled a traitor by the light faction and should join Serpent Academy. Feeling she needs to do something, Hibari decides to go to Serpent Academy so she can retrieve the scroll, leaving a note behind for the others. When Yagyuu learns of this, Asuka stops her before she does some rash, assuring her that she is not to blame. Meanwhile, Hibari arrives at Serpent Academy, where she is enrolled as a student and learns how Homura and the others came to join the dark faction. She is also introduced to their teacher, Suzune, which rings a sense of nostalgia to her. As the Hanzou Academy girls try to determine the location of Serpent Academy, Yagyuu mentions to Kiriya about how Asuka was able to dodge her attack. Later that night, Suzune appears before Kiriya and challenges him to a duel, revealing her identity to be Rin, his former student who was presumed dead. She leaves him a map to Serpent Academy, saying she will be waiting for him there.

A Shinobi Classroom Retrospective

Asuka, Ikaruga, Katsuragi, Yagyu and Hibari are five school girls who secretly train in the ninja arts. As they are sent by their mentor, Kiriya, to handle some delinquents in town, Asuka meets a girl named Homura and helps guide her through town, unaware that she is secretly an enemy shinobi. Meanwhile, the others encounter the delinquents, who are soon revealed to be wooden puppets controlled by an enemy shinobi. As the girls manage to beat the puppets, Asuka remains blissfully unaware of Homura's true alliance.

Ninja That Stand Atop Skyscrapers

As the girls train in summoning animal spirits, Asuka is the only one having trouble summoning hers. Her grandfather, the legendary shinobi Hanzou, comes to visit and informs her that their family's spirit is the tree frog, which Asuka is afraid of. As Asuka attempts to get used to frogs, Hanzou informs Kiriya that the evil Serpent Academy for Girls is behind the puppet attack. On their way home, Asuka and Ikaruga are attacked by one of the enemy shinobi, Yomi.

The Legendary Shinobi Appears

Yomi engages Ikaruga in battle and overwhelms her with her array of weapons before taking her leave. Later, Ikaruga is informed that her brother, Murasame, who she replaced to become the shinobi successor of her family, has gone missing. Later that night, Ikaruga encounters Murasame in her room stealing her sword, Hien, but she manages to send him packing easily enough. After being ejected from the household, Murasame is met by Hanzou, who reminds him that being a shinobi isn't the only way of life. After receiving some advice from Hanzou, Ikaruga decides to start giving Asuka summoning lessons, managing to help her get over her fear of frogs and learn to use her summoning art.

Moonlight Intruder

Kiriya takes the girls to Shinobi Island to train. Two more dark shinobis, Mirai and Hikage, attack. As with the other battles, neither Mirai nor Hikage took their battles seriously and left rather abruptly. However, Mirai revealed to Hibari that she is a freshman at the Serpent Academy for Girls, leading Kiriya to inform his students that these dark shinobis are also from that same academy.

Seaside Training - Shinobi Island

The dark shinobis from the Serpent Academy receive new orders to make an attack on Hanzou Academy. Haruka, the puppeteer, sets up puppets to distract Asuka and the others while a linked barrier is set up to separate the group and force them into their own battles. Asuka finally finds out that Homura is a dark shinobi from the Serpent Academy and is forced into battle. Yagyuu is set up against Mirai, Hibari is set up against Haruka, Katsuragi gets a rematch against Hikage, and Ikaruga is forced to battle against Yomi. This time, the dark shinobis appear to be taking things more seriously. The instructor of these 5 dark shinobis, Suzune, speaks with a mysterious voice about obtaining a scroll known as "Yang" from Hanzou Academy. The Serpent Academy holds a scroll known as "Yin", but their goal is to obtain the "Yang" scroll from Hanzou Academy.

Sneak Attack! Hanzo Academy

The battles from the last episode continue. Mirai loses her battle against Yagyuu, causing the Linked Shinobi Barrier to become weaker and the dark shinobis to retreat. Despite the Hanzou Academy students putting up a better fight, Yagyuu was the only one that won her fight. Yagyuu was injured trying to save Hibari, but recovered quickly. It is revealed that Yagyuu looks after Hibari because Yagyuu sees a lot of her late sister in Hibari. Hanzou returns to the Academy to discuss the situation with Kiriya and informs him that "it is time to find a successor to the super secret ninja arts". The scroll that contains these arts chooses its owner. Who will it be?

Interlocking Shinobi Kekkai Barriers

A woman named Daidouji, a "legendary senior" who has been repeating class at Hanzou Academy of her own accord despite passing the finals, convinces Kiriya to send his girls on "HIKING" training...But this wasn't your typical hike! This was a 2-day trek full of obstacles for each of the students to overcome and make it to the top of a mountain to find the scroll. Asuka learned an important lesson after fighting a giant cat, which seemed to be Daidouji in disguise, in that she worried too much about living up to the fact that she's the granddaughter of a legendary shinobi. And in another nice turn of events, Hibari saved Yagyuu from piranhas. The 5 of them made it to the top at the same time, only to find Daidouji waiting at the top. In order to take the scroll, Daidouji said that they need to defeat her. None of them could do it, but Daidouji concluded that Asuka deserved it the most because of an attack that almost took her by surprise. The scroll reads: "Power is both sword and shield".

Hiking Terror

For most of this episode, we see flashbacks. Each to which flashed back to when all 5 of the girls first joined the Academy. We find out how Katsuragi teaches Ikaruga to open up. And when Asuka first joined, she appeared to be just an amateur, but eventually began showing promising signs. Finally, there was a flashback to when Yagyuu and Hibari had first joined. Once the flashbacks ended, Suzune and the mysterious leader of the Serpent Academy continued to discuss plans to obtain Hanzou Academy's Yang scroll. At the end of the episode, the pin that Haruka gave to Hibari begins to glow, and it appears as though Hibari may have become Haruka's puppet.

Having overheard Kiriya's conversation with Rin, the group make plans to travel to Serpent Academy, with Hanzou giving his approval despite Kiriya's concerns. Meanwhile, Hibari attempts to locate the stolen scroll, where she overhears Rin speaking with her leader about her plan to lure the Hanzou Academy girls in order to utilise the power of the Ying and Yang scrolls, which is seen as an act of betrayal. As the Hanzou girls set off, Kiriya and Daidouji decide to follow after them. As Hibari asks the other girls how they feel about their teacher, she gets the feeling that they're not bad girls at heart. Later that night, Hibari listens in as the other girls are informed of Rin's apparent betrayal and are instructed to eliminate any intruders, with their lives at forfeit should they lose due to a forbidden art placed upon them. However, Hibari is caught by Haruka and locked up alongside Rin. Meanwhile, the Hanzou girls begin their infiltration, with Yagyuu managing to use Hibari's scent to locate the secret entrance to the academy, coming face to face with Yomi.

Ikaruga decides to face Yomi alone whilst the others press onwards whilst Rin, after a brief talk with Hibari, breaks free from her cell. Yomi explains her resentment towards Ikaruga came from her living in poverty and having her parents starve to death whilst Ikaruga lived a rich life in the mansion looming above her. However, Ikaruga responds that would've given anything to have the same love from her parents as Yomi had and comes at her with her full power. Meanwhile, Katsuragi and Yagyuu end up having to face Hikage and Mirai whilst Asuka heads onwards and comes up against Homura. Back at the cells, Haruka explains to Hibari how she was smothered by her mother like a doll before being scouted by Rin. Hibari then fights against Haruka in a hopes of finding a way to break the curse placed upon her and the others. After managing to beat back Haruka with her hidden art, Hibari uses powerful telepathy to inform the others about the curse, urging them to instead find the man who placed it upon them, before Haruka knocks her out. Hearing this, Ikaruga and Katsuragi quickly end their battles and head towards the top of the castle whilst Yagyuu heads to Hibari's location, with Ikaruga telling Yomi about how she was adopted before heading off.

Castle Showdown

As Asuka continues fighting against Homura, she sees a glimpse of her memories, in which she was betrayed by a man she thought loved her and killed him, before using a shockwave technique to escape. Meanwhile, Rin explains to Kiriya how she initially planned to have her students beat his in order to prove herself the better ninja. However the dark faction's leader, Dougen, issued a new plan behind her back to try and combine the scrolls. Whilst Ikaruga and Katsuragi push past Yomi and Hikage, Yagyuu catches up to Hibari and manage to get past Haruka and Mirai. As Asuka reaches the top of the tower and once again clashes with Homura, Dougen makes his appearance, stating he plans to wield the power of the scrolls by using them as vessels. Asuka and Homura are forced inside a shinobi barrier where they must face against Dougen's secret ninja art, Orochi, whilst the other shinobi team up to fight against a legion of mechanical guards. Homura prepares to sacrifice herself to stop Dougen, but Asuka holds her back, asking her to have faith in her friends. Sure enough, Hibari manages to combine her power with the others to break through the barrier, using their spirits to power Asuka and Homura up, allowing them to retrieve the scrolls and defeat Dougen. Pushed into a corner, Dougen sets the castle to self-destruct, so the Serpent girls stay behind to help the other students evacuate whilst Rin sacrifices herself to take Dougen with her. Some time later, Asuka gets promoted before everyone sets off on summer vacation, confident that they will one day meet the Serpent girls once more, as no bodies were ever found amongst the castle's wreckage.

Super-Secret Ninja Art

The Hanzo Academy is a prestigious prep school with a secret known only to a select few. Behind its walls is a training course for shinobi; trained spies and assassins that centuries ago had served the shoguns for their political and military needs. Today the tradition continues with five young female trainees with diverse personalities: the care-free Asuka, fierce yet perverted Katsuragi, the sweet and innocent Hibari, stoic and protective Yagyuu, and their mature, class representative, Ikaruga.
