The head nun Hijiri Byakuren's favorite youkan, Dessert made of sweet bean jelly

which she'd shut in a cupboard to enjoy in secret, has disappeared.

The first one to find out was a pupil who'd turned a blind eye to it.

Not even a starving tiger would dare touch Byakuren's private property.

The villain who would do such a thing was easy to narrow down in the small temple.

They went looking, but one of them was nowhere to be found.
