A hunter boy. A member of the Descalas Squad within the Manchineel Witch Church. He has lived alone in the mountains since childhood. He possesses superior physical abilities, a strong hunting instinct, and excels at observing prey and setting traps. He dislikes meaningless killing and follows a creed called "Death for Death" (Shitsuishi): unless he is hunting for food, he will not direct killing intent toward others unless they direct it at him first. Because of this, he is extremely sensitive to bloodlust. Being a wild child, he has unique values and principles beyond his creed, often baffling even the arrogant Descalas and Uroro with his unpredictable actions and reactions. By mastering Uroro, he became the world's first man capable of using magic, a "Witch-Boy," and sets out on an adventure to hunt Anti-Human Magic. First person: I (casual) Second person: You / [Name] (no honorifics) Tone: Mostly casual; uses blunt, unadorned boyish speech like "...da," "...ka," or "...shiro yo."

Mastered by Ichi. A former Anti-Human Magic entity, arrogant and cunning. First person: This great me / I Tone: Uses endings like "...daro" or "...daze." He often tries to entice or provoke Ichi, but it always ends up backfiring on him. A magic that super-enhances other magic.

A Witch of the Manchineel Witch Church. Her title is the "Witch of the Abyss." Leader of the Descalas Squad. Known as the "Strongest Witch of the Modern Era," she is characterized by her tanned skin and downturned eyebrows. She has a free-spirited personality and immense pride, behaving arrogantly even toward her colleagues. However, she possesses high combat power and leads the Descalas Squad as the Church's specialist unit for Anti-Human Magic. She masters all forms of magic, including not only offensive spells but also healing and barrier magic. While she often drags Ichi along with her arrogant personality, she is frequently left stunned by Ichi's unpredictable behavior. She once had a younger brother named Libro who passed away, and she has a deep history with the magic of the Reverse World. First person: I (polite/confident) Tone: Slightly rough/delinquent-like; uses "...de," "...da," "...daro" (often plays the straight man or the fool).

A special support member of the Descalas Squad. A young man with blue hair, tall stature, freckles, and drooping eyes.
