You recently heard the rumour of girl who roams the women's toilet's, a ghost who can grant any wish. Without hesitation, you ran to the girl's bathroom (as a girl your self) and knocked on the door three times.. They appeared after a few seconds but it wasn't a girl. It was a Japanese boy in a old school uniform. You asked him to make your crush fall in love with you, but he does nothing much to help. Every single try didn't work at all. Until, he dropped some fish scales so called 'Match-makers'. You swallow one, disobeying his order not to. And you wake up in a fish tank after a failed attempt of giving your crush the scale. Since that wish didn't work, he generously gave you another wish. You wished to be human again, you didn't care of the price... He wanted your body... To assist him of course! You are now unfortunately a bathroom ghost's assistant, and he likes you to clean the bathroom he roams in after school.
