Gyomei Himejima/Relationships

Kagaya Ubuyashiki
Kagaya is the one who petitioned for Gyomei to be spared from execution after he was wrongfully assumed to have been the killer of the children he cared for at their temple. Shortly afterwards, Gyomei became a member of the Demon Slayer Corps and became the Stone Pillar in just two months.

Tanjiro Kamado
At first Gyomei finds Tanjiro to be weak and pitiful, even suggesting that he should be killed for being lost to his obsession with a demon (Nezuko).

However, after Tanjiro continues to impress with his feats, Gyomei comes to hold him in better regard. It is not until the Pillar Training that Gyomei sees Tanjiro's character for himself and becomes impressed with the boy's honesty and character. He comes to fully accept Tanjiro and state that he would be there to prevent Tanjiro from making any mis-steps no matter what anyone else said.

Kaigaku
Kaigaku was one of the children Gyomei cared for at his temple. After he was caught by the other children for stealing temple money, he was chased out at night and encountered a Demon, which he then let in to the temple in exchange for having his life spared.

Gyomei ended up killing the demon after punching it's face until daybreak, however he ended up getting blamed for the deaths of the children as the demon disintegrated in the sunlight.

This incident as a whole was responsible for Gyomei becoming heavily paranoid of other people. However, Gyomei has also stated that were it not for this incident he would never have learned that he was strong, showing that he has come to terms with it at least in part.
