Mitsuzō Soroi

Mitsuzō Soroi (揃三蔵) is the personal butler of Satsuki Kiryūin.

Appearance
He is a tall, slim man with dark eyes and neat grey hair, though his hairline is receding in his old age. Given his profession as Satsuki's butler, Soroi is seen dressed in a tuxedo at all times.

Personality
Soroi is diligent, loyal, and humble.

Relationships
Soroi has the utmost respect for Satsuki, and his loyalty is to her rather than her family. Having served her since she was a child, he shows concern for her well-being, but states that it is his duty to support her regardless of her decisions. Soroi is embarrassed when Satsuki reveals that she found his tea bitter when she was younger, but did not have the heart to tell him.
