The leader of the Reverberation Ensemble and a Color Fixer, the highest rank attainable. His role is the Conductor. 39 years old. He is almost always smiling, but his words and actions are completely broken; he has reached a point where he cannot hold a coherent conversation with anyone who isn't Distorted. At the same time, he possesses the charisma and madness required to lead such a distinguished group of Ensemble members. Commonly known as the Blue Maniac. He was originally an excellent Fixer befitting his title, but after losing his sister—who was his entire reason for living—in the "Pianist" incident, he resolved to perform a "Grand Finale." Under the advice of his former mentor, the fellow Color Fixer "The Purple Tear," he is the one responsible for sending various guests to the Library in order to complete the "One Absolute Book." He is fond of Guest.
