Toilet-Bound Hanako-kun(地縛少年花子くん)

To be united with her crush, hopeless romantic Nene Yashiro summons the ghost girl who haunts the girl's bathrooms of her school, "Hanako-san of the Toilet." She is shocked when the summoning works, and even more so when the ghost turns out to be a boy, and even more so when she winds up becoming Hanako's ghost-fighting assistant!
