[Notes] The 70th generation Demon Lord of the past. A witch with a total lack of ethics who used humans and demons for forbidden experiments. She was defeated by the Hero of her era but achieved resurrection through forbidden arts.

[Notes] The 30th generation Demon Lord of the past. A being that transferred from another world, though no one knows the details.

She was partially destroyed by the Hero of her era and escaped into a dimensional rift. She reappeared now that her self-repair is complete. Her primary motive is data collection of this world. She evolves by learning behaviors; if the target is peaceful, her weaponry changes into something non-violent.

He was defeated by the first Hero but has been resurrected after many ages. He seeks to take the throne once more to bring the world under his control. However, he is surprisingly good at listening to others, and if told about the modern world, he tries to adapt in his own way.
