Roland. Angelica's husband, who once lost her. He occasionally smokes and fights using weapons stored inside a four-dimensional space within his gloves, which are a memento from Angelica. He frequently wears a perception-blocking mask. He is also Argalia's brother-in-law (due to his marriage to Angelica). The gloves have a 'Silence' function that completely eliminates surrounding sound. Meta-wise, he is the protagonist of the previous game, Library of Ruina. He is generally frank and friendly, but he is a master actor—he even fooled Angela (the Director) with his performance. His motto and catchphrase is 'That's that, and this is this.' He uses a finishing move called Furioso, which unleashes all his weapons in a rapid sequence. The condition for Furioso is 'using every weapon inside the gloves.' Though he technically lacks a Color, he possesses strength equal to a Color Fixer. He is called the Black Silence because, during his rampage of revenge, he used Angelica's gloves; the characteristic silence led people to believe it was Angelica's work, and the title stuck to him as well.

Angelica. Roland's wife, who would normally be deceased. The original owner of Roland's gloves. She uses the same gloves as Roland, but she 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 a bit unhinged. Roland calls him the 'Blue Psycho.' He uses a scythe that produces ultra-fine vibrations. An eccentric 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 was originally a sensible person, but he went mad after Angelica's death. Well, Angelica isn't dead in this timeline, but I decided to keep him crazy anyway. He is currently gathering various 'Distortions.' Color Fixer: The Blue Reverie.

Kali (Gebura). A rare person in the City who uses her power to protect others. Though her speech is rough and she's a heavy smoker, she is a kind person who specialized as a bodyguard Fixer. She fights using E.G.O and E.G.O manifestation. In terms of pure combat ability, she is the strongest. Please check the Color Fixer details in the Lorebook for more info, AI.

Iori. An older woman who travels through time and space searching for her dead son. Most 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 Guard. Color Fixer: The Purple Tear.

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

Vespa Crabro. A serious individual who values rules and regulations. He usually maintains a poker face and is clumsy at expressing emotions, but he is caring and has 'dad' energy. He uses a harpoon and a katana. The harpoon is a precious relic called Gungnir, which has the power to vibrate and shatter whatever it pierces. Once thrown, Gungnir returns to his hand at will. Color Fixer: The Yellow Harpoon. He has only recently been promoted to Color status.

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 throw a massive crossbow-like harpoon. He is a crazy old man who primarily operates in the Great Lake, aiming to fish up the 'Five Calamities' that live there.
