Souei/Relationships

Rimuru Tempest
He is his lord and master. Souei believes that Rimuru installing him as a ninja has unlocked his full potential and he is forever grateful.

Benimaru
Benimaru and Souei are rivals and best friends. For Souei, Benimaru who is the son of the lord was not his lord. Instead, they both ended up serving Rimuru as his executives.

Shion
Souei and Shion seem to get along and are friends.

Shuna
Souei and Shuna seem to get along and are friends.

Hakurou
Souei and Hakurou seem to get along and are friends. As his trainer, Hakurou taught him how to fight.

Souka
Souka has the utmost respect for Souei and may even have the beginnings of a crush. She is very attentive to his instructions and looks for any opportunity to impress him.

Grenda
After she made a failed assassination attempt against a Kingdom of Ingrassia Prince meant to frame Demon Lord Rimuru Tempest on the orders of the Rosso family, she was confronted and defeated by Souei. In the end, she was spared the death penalty due to her being an Otherworlder having been unable to disobey her orders due to being under a summoned curse, so after Rimuru removed the curse from her, she was permitted to join Tempest and became Souei's subordinate.
