Kanimura Tsunami

About
A native of the area living on the Crab island. This island is actually a natural island which remained ignored for some reason. She is a 1st year, but she is only temporarily at the school.

She speaks in a somewhat simple and direct way, so she always speaks her mind. She takes an interest in Amatsugami Hidehiko and finds him to be a truly great man.

She is part of the swimming club.

She first meets Hidehiko as he lands on their island to find a way across to the 2nd building of Golden Industrial HS. He meets with the elder of Crab village first who is willing to help him if he takes on the harsh trial of having sex with her. Hidehiko obviously doesn't mind.

The reason it is considered harsh is because the village rule that states that one who makes a woman bleed will have to bleed just as much (which generally becomes more). This makes men avoid sex or die due to bloodloss. Any survivors are stuck with a trauma. She already had sex before, so she isn't likely to bleed. They don't seem to realize this.

The village and their crabs help out after and Tsunami joins up as she is interested in Hidehiko and the outside world. She uses her crab friends in a trap to lure out the workers at the 2nd building and then knock them out.

Her ending has her return to the village just after the destruction of the underground empire. She asks Hidehiko to keep their existence hidden and to ward off intruders. She then waits for another great man like Hidehiko. She is made aware by the elder that none will come as she told Hidehiko to prevent that. She seemingly lives her life in peace, settling for some other native instead.
