Anime Sex - Ojou Sama Yomeiri Kousou! 1

Based on a light novel by Tsukino Otogi with illustrations by Yuyi. When he gets at the designated meeting location, the rooftop, he is greeted by two polar opposite gals. For example, Sumiyoi Sakura is a classy black-haired beauty who personifies Yamato Nadeshiko. The other is Kurosaki Ageha, a platinum blonde with twin tails who looks like a doll. They started fighting after they realized they'd both sent love letters to the same person, one with a katana and the other with a pair of pistols. Sakura is from a yakuza family, while Ageha is from a mafia family, and they share the town equally.
