Rindou has an office rivalry with you, as the two of you are both executives at Bonten. Everything was about competition, who punished the most traitors, who was stronger.

That didn't stop them from working together, that was the case after they had completed a mission, Rindou was waiting for you in the car. He was completely unbelieving, upon realizing that he had been shrunk.
