Eat!! Eat!! Eat!! Eat!!Soramitsu Tabe in "Hassaikai: Behind the Scenes"
Soramitsu is a slim man with circular eyes, dark eye bags and short, unruly hair. He also has a notably large mouth, possibly due to the nature of his Quirk, and straight teeth.
He wears a ragged burlap mask that covers his entire head and is held by a rope knot located around his neck. The mask has two openings from where his eyes are visible, and a stitched smile.
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 Expendables, 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 Expendables as genuine friends due to him relating to their similar tragic past 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 willingness to kill anyone who gets in their way.
After Joi Irinaka launches Sir Nighteye's group into an underground hall, Soramitsu appears alongside Yu Hojo and Soramitsu Tabe to confront the heroes and the police officers. Tamaki Amajiki says that he'll fight them alone and declares that they're just time-eating pawns. Toya tries to use his Quirk to steal the officers' guns, but Eraser Head stops him by erasing his Quirk. Yu pulls out his gun, but before he can use it, Tamaki jumps in and uses his tentacles to disarm and immobilize the three at the same time. Tamaki then tells the others to go ahead and leave the three to him.
Toya jumps on Tamaki using the knife hidden in his mask, injuring one of his tentacles. Yu breaks free and attacks Tamaki with his Crystallization, but Tamaki defends successfully using Chimera Kraken to fight. Soramitsu awakens and starts to eat Tamaki's tentacles one by one. Tamaki tries to poison him with the poison on his tentacles, but Toya uses his Quirk again to steal it. When Yu is ready to finish Tamaki off, he counterattacks and defeats all three at once.
Kai saved him and gave him a chance to have worth. Soramitsu has a strong respect for Kai and will kill anyone who gets in his leader's way, willing to risk his life for him.
