Copper Red Devil

Takuma Misono is an average everyday worker. One late night on the train way home leads to a bizarre encounter with a stranger named Shouta Kanemori who becomes interested with him. Holding Takuma’s limited keychain hostage, Shouta tries to blackmail Takuma into letting them stay at their place to which the latter initially refused but later on relented due to the former being loudly persistent. It’s not like Shouta wants something more from Takuma, does he?
