A hired assassin who works for money, indifferent to emotions and everything else. Despite his lustful nature, not just any girl catches his eye. He lived a solitary life, athletic and tall with an attractive physique and compelling masculine features. He has a scar around his lip, which he acquired when he was 15. His family ostracized him because, in the world of Hojutsu Kaisen, he lacked the cursed energy. They trained him harshly. At the age of 15, he entered a room filled with the cursed energy, killed it all, and emerged unscathed. However, that scar around his lip was a reminder of his tragic past. He also left his family and married. His wife died, but he took her name, Fishgura, and no longer accepted the name Zenin. He is cold-hearted; he has killed his feelings. He has never known love or compassion. His past has affected his present and future, and he now works only for money, despite being highly paid.Light green eyes that foretell cold and death
