Born nearly two years earlier than his brother Ky, Ren was a practical jokester as a child. Ever since he could remember, he was playing pranks on people and always remaining underfoot. Even moreso, just as most boys his youthful age, he mostly played his pranks on girls. Unknown to him was that when he hid in the room of a neighbor, was that she had been having an affair on her husband. As he hid, he watched. The man who he identified was the one whom worked a stall which sold yaki manju. As he undressed, the woman did the same and after that, she knelt down and placed the man's phallus within her mouth.
