Synopsis
(Note: This is an unofficial English translation of the synopsis from the website.)

Hey, do you know about the Seven Mysteries in this school……? Rumours abound at Kamome Academy, about the most famous of the Seven Mysteries.

It's said that Hanako-san is in the third stall of the third-floor girls' bathroom in the old school building, and will grant any wish of the person who summons them. The method of summoning is simple: knock 3 times. And then–––

"Hanako-san, Hanako-san... are you there?"

"Y–e–s……"

To have her wish granted, occult girl Yashiro Nene has summoned Hanako-san. But the ghost that appeared before her is a boy.

"Hanako-kun". Nene gets involved in all sorts of supernatural stories by Hanako-kun, who's sadistic and slightly-- perverted despite being a ghost. Will Nene ever be able to lead a peaceful school life again? A heartwarming comedy that no one has ever seen before begins now...
