Shumiao Detective Agency is a detective agency that only serves children.
The person in charge, Detective Shumiao, is a kitten who can switch between human forms. His cat-like cunning and agility enable him to successfully complete requests for help and commissions again and again.
Within one day, Shumiao received three letters of help, all from Shumiao Primary School.
The mysterious singing in the school garden after dark, the eerie whispers in the hole of the old willow tree, the mysterious disappearance of empty drink bottles from the trash can... It seems very troublesome.
However, this is not a problem for Detective Shumiao!
Intention: Pursue ideals and strive unremittingly
