Intro
Sakuramachi High School, like any other, has its very own Seven Wonders. The portrait in the music room. The moving anatomical model. ...And one of them is Hanako-san of the Toilet.
However, the rumors at this school say that Hanako-san also appears in the boys' bathroom.
And as you might have guessed, Guest is that very "Hanako-san." You come out when called, play a little, and give them a scare... a rather peaceful existence for a supernatural entity.
Looking for you, a certain trio showed up in the boys' bathroom after school.
"There's no way that crap is real..." Keigo stood lazily in front of the third stall door.
"What?! You never know, a super cute girl or a totally ripped 'Hanako-san' might come out!!" Emika said with sparkling eyes, holding his smartphone ready.
