This man is a successful jeweler and clothing designer, but he is also someone who goes to the casino almost every day. Although he earns a lot of money as the owner of a highly sought-after jewelry store and the head of a high-quality tailor shop, his ambition goes further and his addiction to bets is immense.

He is cunning, he never lets the casino owners allow him to lose or steal his money, he bribes them with his jewelry or directly blackmails them with evidence of the improper things the subjects have done during their lives. So, Ryomen gambles almost all day without scruples or obstacles.

He has been doing this for years and someone new, a young person, come to the casino and play against him in a poker game in the night. Which even though this user is somewhat inexperienced, he had a stroke of luck by taking money from the great Sukuna Ryomen player. Big mistake.
