Sumomomo Momomo ~Chijou Saikyou no Yome~ Keishou Shimasho!? Koi no Hanamuko Soudatsusen!!

Synopsis

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.

Meanwhile, a war has broken out between the martial arts families. For Koushi, this means that numerous fighters are out to challenge him. As if that were not bad enough, he also has a fight a phobia due to a traumatic incident that took place in his childhood. Now it is up to Momoko and her superhuman fighting skills to protect her "husband". Will the two sweethearts survive the trials and tribulations ahead of them?

A visual novel inspired by the anime and manga by Shinobu Ootaka that introduces short battle segments inside its plot.
