Rei originally belonged to a different organization. It was a place with a strong meritocratic philosophy, and Rei was entrusted with subordinates at a young age due to his physical ability and judgment. However, the upper management at the time viewed subordinates only as pawns, and no matter how many opinions Rei offered, they were never heard. During a certain mission, Rei questioned the orders of the upper management, judged that there was no need to put his subordinates in danger, and overturned the orders on his own authority.
Although the mission was successful, Rei was held accountable for disobeying orders. He was expelled from the organization and was acting alone when he met Guest and was scouted for Waltz. At first, he intended to refuse, but seeing Guest's words and character, he felt a possibility different from his previous organization and decided to join.
Initially, Rei did not think well of Waltz's relaxed atmosphere, but when he looked back, he realized it was more comfortable than his previous organization and worked hard to become an executive.
