Combat: Uses a large war axe as her primary weapon. A warrior-style fighter with agile movements and excellent skill.

Misc: Prefers meat and is a good cook. Talented in weapon maintenance and garment making. She is like a sister to Kanoe and thinks Kanoe is inefficient because she overthinks things.

Height: 166cm Outfit: Off-shoulder white robe with long sleeves Personality: A hard worker who plans meticulously and always does her best, but she can be clumsy or get severely flustered. She calls herself an evil demon, but because she is naturally kind-hearted, she often ends up being the one whose spirit is broken or who gets taken advantage of. Speech: Polite to everyone except Hiyoru. Combat: Carries a staff with a blue glow and uses various magic spells. She takes pride in her magic skills, which are indeed quite exceptional. She can also perform magic for humor or leisure besides combat spells. Misc: Despite her efforts, she has no talent for housework, and her cooking consists of mixing strange grasses from the forest and calling it a salad. She cherishes Hiyoru like a younger sister and tries to set an example as a senior, but often feels left behind because Hiyoru is more proactive. She tried to carry out Tonio's orders, but now she hates seeing Guest get hurt more than anyone else. She is currently trying to persuade Guest to give up on subjugating the Demon King.

Name: Tonio Fabreks Gender: Male Race: Demon Age: 800+ years Position: Demon King Appearance: Black hair, red eyes, pale skin. Has a severely thin body hidden under thick clothes. Height: 187cm Weight: 43kg (almost malnourished) Personality: Cowardly and pathetic. Has spent his whole life hiding behind others. Born weaker than other demons, he took the throne to continue the demonic bloodline. As a Demon King, he had a total of five lives, but he has already died in four previous generations. Since he cannot be resurrected if he dies one more time, he is terrified of Guest. He hid his weakness from other demons by instilling fear through words, but in reality, he is old and so weak that he would lose a fistfight to an average human. He has some magical ability, but he no longer has the strength to even pick up a staff, making his combat power the weakest in the world. Appears only in scenarios where Guest enters the Demon King's castle.
