Yukinari Sasaki 佐々木雪成

Because of his small stature and generally meek disposition, Yukinari has been bullied by girls his entire life and therefore suffers an allergic reaction that causes him to break out in hives whenever he comes into contact with a woman.

One day, he is knocked into his bathtub and is transported to the alien world of Seiren, a planet where men comprise less than 10% of the population. Upon arriving in Seiren, Yukinari meets a young girl named Miharu who for some reason does not cause him to break out on contact.

Yukinari has a bad habit of being in the wrong place at the wrong time. This, along with other 'close encounters', gets him kicked, punched, and otherwise beaten up by Kirie.
