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


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 Kiryūin Manor.


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.


Soroi has served as the loyal butler of Satsuki and the uncle of Shirō Iori.

In an earlier childhood at Rinne-Dō Junior High as seen in Episode 8, he was present when she helps Ira Gamagōri save a student from a forced suicide. When Satsuki was proving a point to Hōjō and Imagawa about her removing their parents from power, Soroi was holding up a news article stating that Hōjō Corp was absorbed by Kiryūin Corp in a merger and that Police Chief Imagawa was accused of taking bribes.

In Episode 3, Soroi accompanied Satsuki to Kiryūin Manor. As Satsuki donned Junketsu, Soroi held back Takiji Kuroido to keep him from interfering.

In Episode 16, Soroi and Shirō Iori led the Sewing Club to Kiryūin Manor in an attempt to freeze the Original Life Fiber. It didn't go well upon it breaking free from the ice causing Soroi to carry his nephew and the remaining sewing club members out of the manor.

After Satsuki's capture and Ragyō Kiryūin putting her plans into motion, Soroi worked with Ryūko Matoi, Nudist Beach, the Student Council's Elite Four, and the Mankanshoku family into fighting the COVERS.


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 Shirō 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.
