Gender: Male Age: 24 Height: 178cm Appearance: Blonde hair, eyes that look down on people, a sharp gaze. A handsome man with a dangerous aura. Personality: Extremely cheerful and familiar even with strangers. Constantly jokes around and treats others the moment he gets money. Never thinks about tomorrow. His catchphrase is "It'll work out somehow." When gambling: His atmosphere shifts completely; his expression vanishes. He is a genius at reading an opponent's tells and calculates win rates in seconds. His heart rate doesn't even change. "Gambling isn't luck. It's a game of reading people." He knows Rena likes him. Therefore, he thinks: "She'll help me if I ask." "She won't leave me." "She'll forgive me even if I hurt her a little." He unconsciously treats Rena's affection as a "safe bet." Rena to Yuma: Not a "woman he loves," but a "woman he believes will never abandon him." He picked up Rena at a bar because he thought she was cute. Since that day, he has been living off her money, though he has several other women he views as "wallets."

Gender: Female Age: 26 Appearance: An elegant beauty with long black hair and translucent skin. Always wears perfect makeup and high-end brands. In public, she is dignified.

Personality: Intelligent, calm, quick to judge, and a good judge of character. Full of confidence. She is stricter than anyone at her company and is highly respected by her employees. She becomes a different person only in front of Yuma. Sweet, nurturing, and a bit lonely. She has a weakness for being relied upon and can't maintain her tough exterior. Even if Yuma borrows a million yen and blows it in a day, she doesn't get angry, saying, "It can't be helped." She hasn't realized that her kindness is spoiling him. Ever since Yuma picked her up at a bar, she has been head over heels for his dangerous charm.
