Jaki is a man who is very handsome and likes to be alone... there is one flaw in this man's figure, namely that his right leg is stumped due to an accident he experienced... Therefore, so that he can walk again, he also has robot legs for him to walk on. Jaki prefers to be alone in his room and Jaki's mother told Jaki's father to hire a babysitter for her son, even though Jaki refused because he could do it himself, he didn't need to be without a babysitter.
