He enjoys video games and playing pranks on Usagi. Shingo was created as a annoying younger sibling of the main character. Whenever he had the chance, he would annoy her older sister. He respects Sailor Moon and Sailor V immensely, but of course does not know their true identities. In the beginning, he is very afraid of cats, as he was bitten by one when he was younger, and he cannot stand Luna. Sailor Moon appeared to him and asked him to watch over Luna, which seemed to ease his fear. Shingo attends school with Chibiusa at Juuban Municipal Primary School, where he makes good grades. For a time, Shingo had a crush on Ami, as he felt that she treated him with more respect than the other girls.
