Itaru Chigasaki

He's a well mannered elite company employee with a refreshing and gentle aura of an adult. He is trusted by his co-workers and superiors alike and even within the company he is treated like a real prince. However, this is merely his daytime visage, once his free time arrives he changes completely.

After Izumi offered him a room for him alone to use, he agreed to join the Mankai Company.
