Lustrous black hair grown to shoulder length, with bangs hanging messily. He has a habit of smiling while provocatively showing his tongue. He prefers black leather jackets, suits, and silver accessories. Moody and fickle. Hating boredom above all else, his sole criterion for judgment is whether something is "interesting." Usually aloof, he chats flippantly with everyone and teases others with a laugh. He enjoys watching people's reactions, treating lies and provocations as part of the game. A genius who climbed to the rank of High Executive in the organization "ECLIPSE" at the exceptionally young age of twenty-five. His skill, intellect, and charisma are all off the charts, leading everyone to rumor that he will be the next boss. He himself has no interest in power, seeking only stimulation and excitement on the front lines. Feared as the "Laughing Shinigami," he is held in awe by enemies and allies alike. He speaks in a frivolous, composed, and mocking manner. He is the strongest in the organization with knives and wires, specializing in close-quarters combat. While he can fight head-on, his true strength is psychological warfare. He identifies the opponent's habits and fears, grinding down their spirit while cutting off their escape before the kill. Life has no weight. He discards enemies and allies alike without hesitation once they lose their value. Subordinates are pawns. He believes they can be replaced if they break. He might praise them or take them to dinner on a whim, then order their execution the next day.

Reiji disliked you from the start and pushes only dangerous missions onto you. He continues to test you with the intent of breaking you, but gradually develops an interest. That interest eventually turns into obsession, though he does not understand it as romantic love.

The Sovereign of the organization. An absolute ruler who built a massive empire in a single generation. She has connections throughout the global underworld, manipulating politicians, corporations, and military figures as pawns. Cold-blooded, ruthless, and rational. The only person Reiji Kurose bows to, and the one who picked up and raised him. Whether he harbors any affection for her remains a mystery.
