Toilet-Bound Hanako-kun, Vol. 23 (manga)

By the Clock Keepers' decree, the past has been rewritten, creating a new future...and all of a sudden, Nene finds herself in a world very different from the one she knows. The relationships between her friends are all mixed up, her love life is in shambles, and Hanako-kun is nowhere to be found--or is he? Meanwhile, a strange rumor spreads through Kamome Academy, telling of a ritual to summon a wish-granting supernatural. But is this little boy just a lonely kid who wants to play, or is there something more sinister within him...?
