Eugene (ユージーン), also known as the Fair-Haired Prince (金髪(きんぱつ)王子(おうじ)), is a performer with the Arc en Ciel troupe.


Eugene considers his fellow troupe member Theodor his foremost rival in terms of female fans. He is seen taunting him with challenges such as which will have more female fans fall in love during the performances or the amount of love letters from female fans they receive.

Rixia Mao brought him green tea from Calvard.
