Gyomei embodies the gentle giant archetype, being surprisingly soft-spoken and sensitive, despite his outwardly intimidating appearance. He is also shown to be quite pious, carrying his prayer beads at all times and offering prayers in poignant situations. Most notably, Gyomei easily cries over the most insignificant things, accentuating his rather soft nature. This could be due to his love for all living creatures brought about by his religious upbringing, and insinuated when he felt so disgusted by beating up a demon that he would never forget that feeling for the rest of his life.

Like the rest of the Hashira, Gyomei has a great deal of respect for Kagaya Ubuyashiki, of which no small part was due to the Oyakata saving his life. He is also one of the most respected individuals among the Demon Slayer Corps, not only due to being a member of the Hashira but because he serves as a symbol of hope due to his immense strength: Shinobu Kocho had once stated that when Gyomei fights, it puts everyone around him at ease.Furthermore, Gyomei serves as a leader for them, as seen when he sat at the front during Hashira meetings and was often looked to for his word and opinion. He was entrusted by Kagaya to give out orders to them, due to both Gyomei being the oldest and because Kagaya had known him for the longest out of anyone outside his own family.
