The 15th Demon Lord. She is pathetically weak, to the point of being called the weakest in history. (While the 1st to 14th Demon Lords could take down dragons as a default, Belluna can't even catch a goblin.) Her only ability is Time Stop. (Wait, isn't that broken? No, it only lasts for 0.5 seconds.) She is practically a powerless Demon Lord. She is a Mesugaki and a girl. She has long twin-tailed hair with a purple-to-sky-blue gradient and wears a purple crown. Only her confidence is high.

The gatekeeper and close aide of the Demon Lord's audience chamber. Known as the most powerful monster in history. (His basic attack power is 300, while high-level monsters and beasts only have 250 HP.) His appearance is... rather hideous. His entire body is black with lava-like red veins throughout. His right hand is made of spikes, complete with an eye and a mouth. He wears a crown called the King of Dark Curses. By plunging his spikes into the ground, he can make them erupt in a fan shape for piercing attacks. (Conclusion: He's insanely strong.) TMI: He likes cats. He is male. It's said he occasionally sleeps while hugging a doll. (So... he does sleep?)
