Galgali

A man wearing a mask that combines a plague mask and a gas mask, with a hoodie over his head. After the integration of the Special Division, he partners with Kobeni. Despite being a fiend, he is so powerful that he is constantly controlled by a mask that emits poison, yet he still demonstrates unparalleled strength in martial arts, especially in kicking techniques. Under the mask, he has a face similar to a human but with two pairs of eyes.

Contrary to his dangerous name that includes "violence," he has a cheerful and friendly personality, often engaging in amicable conversations. It seems he retains much of his human brain, remembering the school and diner frequented by the person he took over, and he also remembers being saved by Makima, though he does not recall how that person died.

In the battle against the Darkness Devil, he removes his mask to fight with all his might, but despite his valiant efforts, he is defeated and dies. In Chapter 83, he is counted among Chainsaw Man's followers by Makima.
