Chapter 1: (y/n)

You're the vice president of the Student Council in Kamome Gakuen, and lately, you've been seeing your best friend, Yashiro Nene, head to the third-floor bathroom every day after school. You follow her and find out she's working with a ghost, who calls himself Hanako-kun of the Bathroom. In between helping Nene-chan clean the bathroom, you also babysit the youngest Minamoto, Tiara, and handle issues with the Student Council. How are you going to work this out?
