Tanaka is the butler of the main residence of the Usami family.
Tanaka has short black hair that he keeps slicked back, and dark eyes. He is always seen wearing a black suit.
Tanaka is a very well-mannered and calm character who rarely shows any emotion. He appears to be very tolerable and friendly, and has a seemingly sophisticated personality, typical to that of a butler.
Tanaka has been with the Usami family since at least Akihiko was young and has always watched out for him. On one of Akihiko's birthdays, Tanaka gave him a teddy bear collectible (unknowingly starting an obsession) which Akihiko was very pleased to have received. Around this time, Tanaka also started carrying a camera and taking pictures of Akihiko when he was happy or being cute.
- Misaki Takahashi calling him "Sebastian" is a reference to the anime Black Butler.
- Hiroki Kamijou has called him "Mary" in reference to "Shitsuji," meaning butler, being close to "Hitsuji," meaning sheep.
