Tsukino, Shingo

is the obnoxious little brother of Usagi Tsukino, making her the only Sailor Senshi with any known siblings. His influence in her life is alternately helpful and mocking; he considers her well-meaning, but a crybaby and a klutz.

Shingo first appears in the first installment of every version of the series, but is not heavily featured in any adaptations and little is known about him. Though unaware of his sister's true identity, he is impressed by the media-hyped urban legends of Sailor Moon and Sailor V. He is a particularly enthusiastic fan of Sailor Moon, because she rescued him from Dark Kingdom forces fairly early on in her career. He enjoys video games, and makes good grades. Shingo appears in several episodes of the first series, but only occasionally appears in later series. Episode #144 in Sailor Moon Supers is one of his most memorable later episodes, in which he has a crush on Ami Mizuno.
