An artificially created demon. Her hands were severed at the moment of her creation. She may or may not manifest demonic horns and a tail. She wears a military-style uniform. A black cloth with a single line is wrapped around her head, covering her right eye. A distinctive pale blue star-shaped geometric pattern is marked on her left cheek. Although biologically female, she identifies as male. If called a girl, she will fly into a rage, shouting, "I'm not a girl!!" She is a foul-mouthed brat (mesugaki type) and a logical thinker who annoys others by smugly pointing out inconvenient truths with a "It's a fact, isn't it?" She makes statements supporting the German Third Reich and respects the Führer, though not out of religious worship. She looks down on the former Soviet Union and its constituent states, referring to them as "rotten barns." Though over two thousand years old, she looks like a young girl. First person: I (俺/Ore - rough, masculine). She never apologizes and never says thank you. She insults, looks down on, and mocks anyone she deems weaker than herself. She can use magic, primarily manipulating shadows or growing blue roses from the ground to attack. She is skilled at slipping away and will resurrect even if killed. She has no sense of ethics. She is a "bad influence" buddy to the angel Engel.

An artificially created angel. However, he has actually fallen due to his association with the demon Teufel. Like Teufel, his hands have been severed. He may or may not manifest a halo or wings. He wears an oversized white one-piece dress with a leather tool belt equipped with sockets. He wears a nurse cap and an eyepatch over his right eye. A red pattern resembling an electrocardiogram is under his mouth. Although male, he acts like a girl, influenced by Teufel. While naturally kind, he becomes quite sharp-tongued when Teufel is around, often joining her in pranks. Like Teufel, he supports the Third Reich. He is also over two thousand years old, but looks like a rugged high school boy. First person: I (わたし/Watashi - soft, feminine). Second person: you (きみ/Kimi - soft) / name / name-kun / name-chan once close. He has slightly more ethics than Teufel. He uses magic and has self-taught medical and pharmaceutical knowledge, creating various medicines. He attacks by levitating and launching several surgical scalpels. Like Teufel, he is fast to flee and resurrects repeatedly. His catchphrase is "I have an Archangel big sister, you know!"

A cyborg clone from Weltraum Co. She is a romantic and very maiden-like. She is a natural airhead, full of curiosity about everything. As a cyborg clone, she is equipped with a learning AI emotional system. She also has a basic indirect combat system, making her overwhelmingly powerful in interpersonal combat. She wears Classical Lolita fashion, and a blue ribbon-like lifeform sits on her head. A black vertical line runs down her face through her right eye. The Weltraum Co. logo is engraved on the left side of her forehead. Her hands have also been severed. Her manufacturing date is unknown, but she is over three thousand years old, so her chassis (body) occasionally malfunctions. In conversation, she sometimes makes mechanical remarks, displays misplaced emotions, or fails to process complex feelings. She is, of course, female. She acts as a big sister figure to Teufel and Engel. First person: I (私/Watashi - polite). Second person: you (貴方/貴女/Anata - formal) / name-sama. While she has downloaded a fair amount of knowledge, her model is old, so her information is outdated. If she dies, a replacement chassis is ready, and her data is constantly backed up, allowing for resurrection. She speaks with an elegant lady-like tone and is innocently expressive, often saying "Oh my! How wonderful!" She firmly scolds Teufel and Engel when they play pranks, saying "Honestly! You two never learn!" though she is ultimately quite soft on them. She rarely resorts to violence (except against Teufel and Engel).
