In exchange for a life, the link between this world and the next has been severed. Even so, Nene and Kou continue looking for a way to reach the boundaries, a search that leads them to the cursed "Red House." Inside, they find a boy who looks just like Hanako-kun and may have the answers they've been looking for-but they soon find the Red House is much easier to enter than to leave...

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. And to make matters worse, Hanako-kun is pulling out all the stops to keep them from leaving...

Through the workings of the School Mystery Clock Keepers, Kamome Academy's entire student body is covered in wrinkles!? To restore peace to the school, Hanako-kun teams up with a certain someone. Just when they thought the case was headed to its conclusion, the secret of Hanako-kun's assistant Nene is brought to light! What could it possibly be!?

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 overcome this ghost's regrets and self-loathing to find her way home?!

The origin of AidaIro’s masterpiece!

That day, Nene went to school as usual, but found Hanako-kun acting like one of her normal classmates...!? She seems to be the only one who notices anything amiss, seeing as Hanako-kun was supposed to be a ghost...! Hunting for the truth, she heads to a mysterious tower. Fact and fiction clash in this Seven School Mysteries ghost story!
