すもももももも〜地上最強のヨメ〜 継承しましょ!? 恋の花ムコ争奪戦!!

Inuzuka Koushi is a smart high school student who aims to become a public prosecutor. Unfortunately for Koushi, he was born into a martial arts family whose head (i.e. his father) only knows one language: violence. When Koushi was still a baby, his father made a pact with his biggest rival to marry Koushi to his opponent-turned-friend's daughter. The union of the two blood lines is supposed to bring forth Earth's strongest martial arts clan.

Now, Koushi is in high school, oblivious to the marriage arranged for him at birth, when Kusuryuu Momoko shows up: a sugar bomb, airhead, young-looking martial arts artist and Koushi's self-proclaimed bride (the strongest on Earth, no less). Her wish for sexual intercourse meets with Koushi's square refusal as he has absolutely no desire to get it on with someone who looks like she could be his little sister, not to mention that he does not have the foggiest idea who she actually is.
