The guys decide to all get together and tell Kae how they honestly feel about her along with Mutsumi. Kae decides to go on a date with all of them individually to decide who's feelings she will accept.

A new anime, Katchu Ranbu, or Kachu Rabu for short, has started, and it's hugely popular. Bot Kae and Nishina are elated about the show, until they find out that they each ship Lord x Akane and Akane x Lord respectively and get into a huge fight. Their friendship appears to be heading to a halt, so Igarashi, Nanashima, Shinomiya and Mutsumi try to help the pair out. Unfortunately, it looks like their reverse ship war is just heating up.

After the group's pilgrimage is over, Nanashima begins to notice there's been a change in Kae's relationship with others in the group. Nanashima realizes his only advantage is that he looks like Shion, and with Shion out of the picture, he's lagging behind the rest. While dancing a dance from Puri Puri Moon with his little sister, Nanashima decides he needs to be more proactive. Meanwhile, Kae has decided to take up a part-time job at Usami Land to raise funds for upcoming Kachu Rabu events.

Everyone goes together on a one night trip in order to attend the death anniversary of Hyakki Sametora, the samurai the lord in Kachu Rabu is modelled after. Both Kae and Nishina are enraptured by the real armor and helmet Akane is modelled after, and a portrait of Sametora. After, Kae and the gang decide to go to a small island in a lake where Sametora's head is rumored to be buried. But what will happen next?

For the school cultural festival, Kae's class decides to host a cosplay café. Kae is fired up about designing the costumes not only for her classmates Igarashi and Nanashima, but also for Shinomiya, who's playing the role of a princess for his class which is putting on a play. But as excited as she gets about the costumes, she also has to help the history club set up its exhibition. With everyone's help, she manages to finish everything in time for the festival. And what follows is a date with the four hot guys...

After having lost weight, Kae does extremely well in PE class. Seeing that, some girls from the soccer club ask Kae to help play in a practice match. Kae has full confidence in her soccer knowledge, but she actually only knows soccer from soccer anime and has never actually played herself. And so, Igarashi from the soccer club, as well as Nanashima, Shinomiya and Mutsumi try to help her out.

With Christmas around the corner, Nanashima suggests everyone have a party. However, Kae says she can't possibly make it because she's going to Comiket. In the end, everyone decides to go to Comiket together, then have a Christmas party afterwards. The boys are bewildered at their first visit to Comiket, and feel as though everyone is looking at them askance. Meanwhile, Kae is busy bustling about the entire venue, until she runs into some trouble at the cosplay plaza. And then, a handsome cosplayer saves her.

The six go to Nishina's holiday house by the ocean to swim. Everyone has fun bodyboarding, eating at a beach hut, and playing beach volleyball. But while doing so, Shinomiya realizes just how unreliable he is and loses confidence in himself. What exactly can he accomplish? After another failed attempt to be useful at the evening barbecue, Shinomiya runs off on his own.

Mutsumi tells his brother Kazuma, "Serinuma-san is my girlfriend." However, Kazuma keeps on pursuing Kae, now with even more gusto. Igarashi, Nanashima, Shinomiya and Nishina all try to band together to get in Kazuma's way.

The anime Mirage Saga is hosting a Valentine's event, and Kae decides to make a chocolate for Shun for the event. As Kae fusses over what chocolate to make in order to perfectly capture Shion's beauty, Nishina suggests Kae try making a 3-D chocolate sculpture. Kae agrees, and throws herself into making one, but is unable to improve in her ability to sculpt the chocolate at all. Nishina can't bear to see Kae saddened by her situation, so suggests Kae use the chocolate she made instead. What will Kae decide to do?

Mutsumi finds a hidden treasure map in the History Club room and invites everyone to go treasure hunting. Igarashi, Nanashima, Shinomiya and Nishina are less than thrilled about the idea, but after finding out Kae would be going alone with Mutsumi, they decide to go too. The four of them are confused by Mutsumi, because he treats Kae now the same way he always had. And so, they decide to ask him how he really feels.

Kae Serinuma is what you might call "fujoshi". When she sees two boys talking, she starts to rave in crazy thoughts! One day, the favorite character of her anime dies, and the shock is enough to lose weight. With this, four school boys decide to call her out, but she does not seem to care - she'd find much better to see them all making out!
