The origin of AidaIro’s masterpiece! Toilet-bound Hanako-kun was originally published as a self-contained short series, and you can read those three chapters here along with AidaIro’s debut work, “My Dear Living Dead.” If you want to see Nene try to curse her ex to death, Kou fall off a roof (more than once), or Hanako-kun butt heads with a new group of School Mysteries, come and see where it all began!

After going to rescue Aoi, Hanako-kun and Nene are thrown from No. 6’s boundary and suddenly find themselves in a strange village, where they meet a girl named Sumire who seems to have a history with No. 6. Witnessing Sumire’s “wedding day” up close might just give Nene a hint on how to resolve the school’s impending crisis and save Aoi—but she’ll have to survive it first! Meanwhile, on the very banks of the Far Shore, Aoi and Akane finally put into words exactly what they mean to each other...

Shijima-san is willing to help Nene and her friends escape from the painting, but they don’t have much time to reach the distant exit before they’re trapped inside for good. To make matters worse, Hanako-kun is pulling out all the stops to keep them from leaving. And when Nene puts everything she has into trying to convince him to let them go, she’s shocked by the genuine emotion that wells up from him in response...

Nene and Akane are rescued from the clutches of a horde of supernaturals by School Mystery No. 6... who then immediately kidnaps Aoi?! With so many School Mystery seats unfilled and the long, dark night of Urabon here at last, this ancient supernatural knows that Aoi may be the only one who can save the school from disaster—but at what cost?

At long last, Hanako-kun reveals his plan to save Nene from her inevitable, swiftly approaching death. But even knowing his intentions, Nene is determined to return to reality—and to do that, she’ll need the help of School Mystery No. 4, Mei Shijima. Can Nene help this spirit overcome her regret and self-loathing and find her way home?!

Nene’s best friend Aoi has been trapped on the Far Shore— but to Hanako-kun, who has been worrying for ages over how to save Nene from her rapidly approaching death, this turn of events is exactly what he needs. Nene and Akane have no intention of letting Aoi be sacrificed, but when every supernatural in the school starts to disappear, they realize it may already be too late. Is it time to say goodbye to the paranormal inhabitants of Kamome Academy once and for all?!

After being ripped apart by the severance between this world and the next, Nene and Hanako-kun are finally reunited. That being said, it’s not exactly a happy reunion. With their emotions running high over the seemingly intractable problem of her nearly depleted lifespan, they’re all too quick to give in to anger. Meanwhile, as the Minamoto brothers have a spat of their own, No. 6 shows up out of nowhere―and he’s out for blood…

Nene has managed to escape the final resting place of all the kannagi sacrificed in this town, reuniting with Kou and the boy they now know to be a younger version of Tsukasa. As the beginning of the Yugi family tragedy is finally unveiled, Kou sees a chance to put everything to rights—if they can all escape the Red House. But this cursed mansion has already made the consequences of trying to free Tsukasa from its clutches very clear...
