Sumomomo Momomo: Chijou Saikyou no Yome (すもももももも ～地上最強のヨメ～)

Inuzuka Koushi is a smart high school student who aims to become a public prosecutor. Unfortunately for our good guy, 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.

Skip forward: Koushi is in high school, oblivious to the marriage arranged for him at his birth. Enter Kusuryuu Momoko: sugar bomb, airhead, loli 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 doesn't 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 weren't bad enough, our protagonist also has a fight 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? More importantly, will Momoko get her way receiving a baby from Koushi?

Nagasarete Airantō (ながされて藍蘭島)

Ikuto Touhohin just had a fight with his old man, one that led him to make a rash decision to run away from home. He boards a ship, deciding to take a vacation, but the ship is suddenly hit by a huge storm - one that sends Ikuto overboard! When he regains consciousness, he realizes he is still alive… on some island. An isolated island. An isolated island with nothing but girls. Beautiful girls. Stranded on an island with only girls, no electricity, gas, radio, television… like he was back in the stone age.

Nagasarete Airanto revolves around Ikuto Tohoin, the main protagonist, who ran away from home because of a fight with his father. Due to a life-long dream of wanting to board a ship, Ikuto decides to take a vacation on a cruise ship; the ship is suddenly hit by a huge storm, throwing Ikuto overboard. He wakes up the next day to discover he is on an uncharted island populated by girls. Ikuto finds himself to be extremely popular on the island, due to the fact that no other men currently live there. As a result, nearly the entire island starts pressuring Ikuto to become their husband — all except a young girl named Suzu and her extremely old grandmother. Suzu's grandmother decides that Ikuto will live with Suzu for the time being, but Ikuto initially finds it difficult to adjust, especially with the entire island population after him night and day. Meanwhile, Suzu does her best to protect Ikuto from the masses. However, Ikuto still does not want to stay on the island, and soon after arriving, he attempts to leave by boat, but discovers the island is completely surrounded by whirlpools and tornadoes, eliminating escape by sea or air, thus impossible to leave. With no other choice, Ikuto starts to settle into life on the island.
