Soramitsu appears to be insane. He is also always hungry and thus obsessed with eating. His Quirk and personality made it difficult for him to conform into society.

Soramitsu, just like other members of the Eight Bullets, is a hopeless person who lost his dignity and no longer sees any purpose in continuing to live and therefore is completely devoted to Shie Hassaikai. He is not afraid of giving away his life for the group. He values his fellow Bullets as genuine friends due to him relating to their similar tragic pasts and lack of worth. This friendship proves to be very strong as he was not willing to eat Yu Hojo, despite his dedication to Overhaul and his willingness to kill anyone who gets in their way.
