Noppo

のっぽ

Noppo is a character who appears to enjoy eating, as demonstrated when he consumes various items in his debut music video, How to Devour Life.
Despite his frightening appearance, Noppo is actually depicted as kind and caring; for instance, he protects Inochi from the Headless Dragon and stops him from smoking. This is also confirmed on his character sheet.
Noppo takes the form of a tall, slender, gray mass. His face consists solely of a mouth, typically displaying a toothy grin. He has large hands, with an eye on the back of each one. He can also stretch his jaw and elongate his tongue.
Noppo wears a black robe with orange lining and three orange buttons, and he goes barefoot.
Although unconfirmed, Noppo seems capable of transforming into a duffel bag, with teeth replacing the zipper. In this form, he has a larger tongue and can eat other Zingai, such as when he consumed what appears to be a Kuroko at the start of How to Devour Life.
By the end of How to Devour Life, he becomes noticeably larger. His robe becomes more form-fitting, covering his arms and hands, and his teeth grow bigger.
