Jotaro Kiriyama (桐山丈太郎, Kiriyama Jotaro) was a very wealthy older gentleman who became friends with Chibi Chibi and gave her an antique doll to play with. When Sailor Aluminum Siren took his Star Seed, he turned into Sailor Antique (セーラーアンティーク, Sērā Antīku) but was saved by the Sailor Starlights and Eternal Sailor Moon.
