Hyougintou is a character created by Tsuda Nanafushi for his Rozen Maiden-based series “Suigintou's Personal Life” (水銀灯の私生活). Hyougintou is a dead ringer for Suigintou and a close friend of hers, but where Suigintou is a TV drama actress (in Tsuda's series) Hyougintou is an AV idol. She has yellow, orange or brown eyes, compared to Suigintou's red or pink.
