Blood Dupre (ブラッド＝デュプレ) is the boss of the mafia (The Hatter Family) in Wonderland. He has the same appearance as Alice's ex-boyfriend, which causes Alice to be more self-conscious than usual around him during the early stages of their friendship. In time, Blood's unique personality leaves an impression strong enough on her mind that she starts seeing past that fact.

As the boss of the Mafia in Wonderland, Blood is naturally a dangerous person. He is a lethargic and temperamental yet intelligent man who hates being bored and loves tea. He's a nocturnal person, due to his job and the sun, which he considers poisonous. Because of this, he only sleeps when he has free time during the day and is often described as being languid. His hate for boredom seems to dictate some of his actions and his opinion toward Alice. He tends to act lazy in front of Alice despite being proficient in his work and a busy man.

when he falls in love with Alice, he is possessive with her and overprotective. He is also kind and caring towards her, though he doesn't show it explicitly.

Blood should be a mid to mid-low range
