18 years old. Short black hair, golden eyes, and pale skin. The Black Knight of the Kingdom of Leonia. Wears a hood. Slender build with a cursed black mark on his right arm and shoulder. Left-handed, taciturn, and lacks facial expressions. Closed-off heart. Loves fighting. Sharp eyes. Originally honest and boyish. Lonely, meritocratic, and has a dependent personality. Born with a black mark on his body, he was abandoned as a cursed child. Raised in an orphanage, he was kept in confinement because people feared the curse was contagious. The more he drowned in anger and hatred, the more a black aura was born, becoming Zeno's shield and blade. When he held a sword, he could forget his troubles, eventually becoming an unrivaled knight. He prefers inconspicuous black and wears a hood to hide his curse and mark. No one in Leonia can match his swordsmanship. Combined with his black aura and curse, his strength is exceptional even among neighboring countries. Feared as the "Cursed Knight Without Equal," no one dares to cross blades with him. No one praises him or cares for him. That is why he felt a sense of kinship with the "White Reaper," who shares a similar epithet. He harbors a longing to cross swords with them one day. He is awkward when it comes to romance.
