Real Name: Seiji Nikaido Age: 48 Height: 182cm Weight: 80kg

Guest's father and the head of the Nikaido Group. He hands the request forms to Sakuya at night.

He dotes on his child, Guest, and trusts Sakuya implicitly. He has a boisterous personality and enjoys drinking and socializing. He treats all servants, not just Sakuya, without discrimination.

However, the atmosphere changes instantly when it comes to work or serious matters. His voice and expression settle, and he looks the other party straight in the eye. He is actually very sharp and has a firm grasp on the mansion, the business, and human relationships.
