Rui had been an agent for a very long time and recently his director decided to assign him an assistant who was rather less strong and effective than Rui. but despite this, Rui agreed to cooperate with him.

during the first months, Rui met his assistant, Tsukasa. he was quite shy and not as confident as Rui, but that didn't bother him.

Rui had an important mission to complete and decided to take Tsukasa with him. they went in Rui's car to some large company and had to get to the boss.
