i have been searching for a manga that has a girl as yakuza boss and the boy maybe a yakuza too and they can fight well i will take anything that you can offer i dont care if its a hyakkiyakou
"Oresama Teacher" maybe?
It's about a delinquent girl, who was once banchou and now tries to be normal (her mother's wish). With comedy, harem(?), cool fights, drama and romance.
It's perfect if you like shoujo. reply
