Ojou-sama Yomeiri Kousou

Amakawa can consider himself a very good looking guy, since one day he receives two love-letters from different persons but with the same time and place of meeting. As he proceeds to the spot, what he discovers shocks him: the girls writing him are two completely opposite persons, with a blonde that is part of the mafia and a brunette that is part of the yakuza, both rivaling factions.
