Takeshi Koumoto (コウモト タケシ, Kōmoto Takeshi) is a young boy of toddler's age who dies due to parental abuse (his mother's boyfriend beats him to death for eating his pudding). He draws a fictional hero called "Muscle Rider" before his death, and when he awakes inside Tokyo room as a participant in the game he believes that Daizaemon Kaze is his "Muscle Rider." To no one's surprise, he still does.
