Ken was a member of Dosu-Roku's gang, he is seen harassing Akira and Miki along with Dosu-Roku and Meri-Ken Jou. He later started to annoy Akira again threating him with a knife but Akira simply smacks him out of the way. Unlike Dosu-Roku Meri-Ken Jou, Ken was not seen again so his ultimate fate is unkown.
