Keiki Kiryu is a kind-hearted high school student surrounded by attractive girls. One day, he finds a love letter with no sender information, other than a pair of panties. Keiki begins his investigation by speaking to his senpai, Sayuki.
If society must clean to survive,
it should just die off!
Eine Zivilisation, in der man
putzen muss, kann ruhig untergehen!
No tenemos que limpiar
para sobrevivir.
Se tiver que viver sempre
limpando, eu morrerei!
