Ryusuke, known as Ryux in the band Moi dix Mois, is an outgoing, shy and energetic man in his early 40s, but he looks quite young and attractive. While performing live for Moi dix Mois, he is the second guitarist and the second vocalist. His hairstyle is eccentric, with both messy pigtails and braids at the same time. His hair in the band is usually blond, but in reality he has black hair. His makeup is heavier around the eyes, seen with black eye pencil even outside of performances.
