18-year-old Swiss former assassin from the Diamond Syndicate. His former lover Count Larken told him not to return until he could kill Bancoran, but ended up reforming and becoming Bancoran's domestic partner. He has a ferocious temper and seethes with jealousy whenever a bishōnen is in Bancoran's vicinity. He beats the snot out of Bancoran on a regular basis, regardless of whether or not he cheats, and somehow got pregnant twice, despite being completely male. His pregnancy is cut out of the anime. In the manga he first gets pregnant in volume 10, and gets pregnant a second time in volume 46 (when he has Figaro).
