Mitsuzō Soroi

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

Appearance
He is a tall, thin 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. Surprisingly, he has the strength to carry several people, as shown during an escape from the Kiryuins' mansion.

Personality
Diligent, loyal, and humble. Soroi is a devoted servant to his master and supports her unconditionally. He was greatly embarrassed upon learning that Satsuki found his tea bitter in her youth.

Satsuki Kiryūin
Soroi has the utmost respect for Satsuki, and his loyalty is unwavering, to the point that he aids Satsuki in her plot against her own family. Having served her since she was a child, he shows great concern for her well-being, but states that it is his duty to support her regardless of her decisions.

Shirō Iori
Soroi is sometimes shown alongside his nephew, Iori, a fellow subordinate of Satsuki's. After a failed attempt to subdue COVERS, Soroi can be seen carrying his nephew and several other Sewing club members to safety.
