Please help me ~ I need a manga with a Painfully dandere heroine.
Some one like Nagato Yuki chan would be perfect.
Kimi Ni Todoke, Hiyokoi, Nagato yuki-chan ect . . . .
Some other anon requested it be identified the other day.
Socially-uninhibited girl has a job cleaning toilets, does inappropriate things to her new colleagues.
It's a pun, because "henn-jou" is short for "weird girl", and a "bennjou" is a toilet.
