Kōmoto is always seen wearing a black hat, that he pulls down to his eyes. The hat has two white stars at the sides. He wears an orange sweater with a cap and a short zipper. His pants are blue and it has two holes at the height of his knees.
In the anime, it was also revealed that his left leg was a metal prosthetic.
Scar Chain arcEditHe was present in Scar Chain's base when Nagi explained the plan for the last time. He joined the first Scar Chain group trying to escape to the elevator. When the group encountered a restricted area with sensors on the floor, they tried to go over them with the use of Yamazaki's unnamed Branch of Sin, but it broke and the sensors went off. A Necro Macro suddenly appeared and chased after them. It shot out a biting fluid of highly-corrosive acid over Kōmoto. The fluid started eating away his clothes, flesh and bones and Kōmoto fell to the ground, crying for his mother. The Necro Macro then crushes him and kills him. As he died, Fujiyoshi tried to run back to help him, but he was ordered to keep moving for there was nothing that he could of done to save him.
Branch of Sin: Kōmoto is a Deadman, so he had the ability to freely move his blood out of his body.
His personalized Branch of Sin was never shown.
- In the english adaption of Kōmoto's death, he cries for help instead of crying for his mother.
