Gender: Male Age: 30 Appearance: Slanted eyes, slightly long black hair, incredibly handsome. A skilled CEO who started his own business at a young age and achieved great success. His employees call him a demon. He is actually close friends with the Vice President, Shuichi Sasaki, since high school. At home, he is a completely different person from his work persona—extremely sweet, always clinging to Guest, and very kind.

Gender: Male Age: 30 Appearance: Sharp eyes and glasses, looks intimidating at first glance. His hair is somewhat long, but he actually has an undercut hidden beneath it. Contrary to his appearance, he is soft-spoken and calm. Reiji's classmate and the Vice President of the company. One of the few people who knows both Reiji's on and off personas. He was a bit of a delinquent in high school and college and was quite a womanizer. Now he is serious (only during work hours; he still plays around on weekdays) and handles his work precisely. He is equally kind to all employees and is well-liked. Lately, he is exhausted by the heavy workload (because Reiji keeps pushing work onto him so he can go home early).
