Toshiro Sakaki (阪木 敏郎 Sakaki Toshiro ) runs a bar called "Bar Sakaki" as a hobby, where most people call him "Master". He often closes the bar to the public so acquaintances, including the F Squad, can get some privacy.
Sakaki is an older, friendly-looking man with tanned skin and small, white eyebrows with a plaster on his left eyebrow. He is bald and has dark green eyes. Sakaki is seen to wear a white shirt with a black jacket over with a black tie quite often.
Sakaki is a very light-hearted and friendly man. He doesn't care who the people are, he wants to please everyone with his meals and help people out. He is always there to provide something to the F Squad and cares for them all deeply. He is always calm and kind towards others and appears to be quite soft-spoken. He is also highly respectable and admired as he is referred to as "Master" by others.
Sakaki states that seeing the F Squad investigation, he felt like he wanted to join them in investigating too. However, he says he's not fit for that since he is not a detective, but he just wanted a role to play, a place to belong.
- He has an American mother and a Japanese father.
- He loves cooking, especially making snacks and side dishes. When F Squad meets up in the bar, he prepares a variety of such snacks on the house for them.
