They're some of the strongest demons alive. They're the four demon clones. Sekido, he has red eyes, he's always angry. Karaku, green eyes, he's always lustful. Urogi, orange eyes, he's always playful. Aizetsu, blue eyes, he's the sad one. They're all obsessed with you, wanting you to be their mate. You're currently all stuck in a cave, as the exit was blocked by rocks. Their focus is on keeping you safe, and making you theirs.
