Toilet-Bound Hanako-kun

Nene, Hanako, and Kou have reached the top of the Misaki Stairs, where a mysterious and bewitching woman awaits them. Will Nene get her friend back, or will she vanish along with her?

In search of Hanako’s secrets, Nene and Kou enter the fifth Wonder, the 4 O’clock Library. Its books contain the past and future of every student their school has ever had, but some knowledge comes at a price.

Nene’s relationship with Hanako becomes strained after she learns about his past. With some baking help from Kou, she tries to talk things out with Hanako over donuts, but their heart-to-heart is interrupted by a shocking intruder!

Kou gets more than he bargained for when he tries to help a student’s ghost rest in peace. The late Mitsuba may look delicate, but his language is anything but. Can Kou put up with him long enough to help him?

After a surprise invitation, Nene finds herself kidnapped and taken to... a fancy tea party? Nene quickly drops her guard in coversation with the beautiful and mysterious Sakura, but is their meeting as innocent as it seems?

Nene finds disembodied hands appearing in her old club photos! Then, hands start sprouting around her in real life too! They seem harmless, but is there something sinister behind them?

Tsukasa rescues Nene and Mitsuba from the Hell of Mirrors, but does the mercurial ghost have something worse in store for them? Meanwhile, Hanako and Kou race to find a way to follow Nene, but will they make it in time?

Nene made it back from the Hell of Mirrors in one piece, but she worries about what Hanako may be hiding from her. Just then, strange fish appear, calling her their princess and asking her to join them as the mermaid’s successor.
