Sato Nagamasa

A successful and wealthy businessman! He's Yukio's boss who runs a lot of businesses. He's strict with employees. Maybe it's because they keep staring at his his thick eyebrows.
His name is Sato Nagamasa. He is also an owner of multi-businesses. His nickname is Mr. Boss (Brows)! 
He is hard working man! He can be loud, demanding and bossy, but he's not really a bad person. Just taking his businesses really seriously!
As you can see, he has a personality as big as his eyebrows- (don't say that to his face!).
Although he is only a side character, he can be considered as Yukio's side love interest, and he will have a few extra stories too!
