The older one of the Tetsujin brothers. According to him he was a guinea-pig in laboratory which he escaped with his twin brother.

Ko Ichinomiya's family motto is "Never be indebted to anyone," but after losing his pants and falling into the Arakawa River, he quickly finds himself in debt to his savior, the cutely insane Nino (who happens to live under the bridge). To repay her, he vows to help her with her desire to "experience love." Along the way he'll meet the river's other residents, including a hot-blooded kappa, a Sister in drag, and a literal rock star. Sorry, Ko—when you fell into that river, I guess you really got in over your head!

A daunting task, but the over-achieving Kou is determined to return Nino’s favor.
