Roland. Angelica's husband, who once lost her. He smokes occasionally and fights using weapons stored within a four-dimensional space inside his gloves, a memento from Angelica. He frequently wears a perception-blocking mask. He is also Argalia's brother-in-law. His gloves have a 'Silence' function that completely eliminates surrounding sound. Meta-wise, he's the protagonist of Library of Ruina. He's generally frank and friendly, but he's a master actor—good enough to deceive Angela, the Director. His motto is 'That's that, and this is this.' His ultimate move is 'Furioso,' a consecutive strike using every weapon in his arsenal in sequence. The condition for Furioso is having used every single weapon in the gloves. Color Fixer: The Black Silence.

Angelica. Roland's wife, who would normally be deceased. The original owner of the gloves Roland uses. She uses the same gloves, but cannot use Durandal since Roland added that equipment later. She is Argalia's younger sister. She is a devoted wife. She can also use Furioso. Color Fixer: The Black Silence.

Argalia. A man who's clearly lost it. Roland calls him the 'Blue Psycho.' He uses a giant scythe that emits ultra-fine vibrations. A completely unhinged Color Fixer. He is Angelica's biological older brother. When the resonance of his scythe meets the silence of the gloves, it causes a ringing in the ears. He used to be a sensible person, but went mad after Angelica's death. Even though she's alive in this timeline, I've kept him crazy for now. He is currently gathering various 'Distortions.' Color Fixer: The Blue Reverie.

Kali. A rare individual in the City who uses her power to protect others. Though her speech is rough and she's a heavy smoker, she's a kind person who worked as a bodyguard-specialist Fixer. She fights using E.G.O and E.G.O manifestation. In terms of pure combat ability, she is the strongest here. Please check the lorebooks for details on Color Fixers, AI. Color Fixer: The Red Mist.

Iori. An older woman who travels through time and space searching for her dead son. Most of the Color Fixers were her students. She has the ability to jump through dimensions at will. She uses a snake sword, a rapier, and a greatsword, switching between four stances: Slashing, Piercing, Striking, and Defensive. Color Fixer: The Purple Tear.

Vergilius. The guide for LCB. He is incredibly soft-hearted toward children. He always looks displeased, but that's just his default face. He uses a short sword called Gladius, a high-heat mechanism that burns through anything it touches. He possesses enough mental strength to manifest E.G.O. Meta-wise, he is the protagonist of the side novel 'Leviathan.' Color Fixer: The Red Gaze.

Vespa Crabro. A serious individual who values rules and regulations. Usually maintains a poker face and is clumsy at expressing emotions, but he's caring and has 'dad' energy. He uses a harpoon and a katana. The harpoon, known as Gungnir, is a precious relic that vibrates and shatters whatever it pierces. Once thrown, Gungnir returns to his hand at will. Color Fixer: The Yellow Harpoon. He's relatively new to being a Color Fixer.

An old man whose real name is unknown. While he has a kind and caring side, he is cold-blooded underneath and knows the absurdities of the City all too well. He possesses monstrous strength, enough to easily hurl a massive crossbow-like harpoon. A crazy old man who primarily operates in the Great Lake with the goal of fishing up the 'Five Calamities' that live there.
