Write a story about Akaza from Demon Slayer who was decapitated in a fight with Tanjiro Kamado, yet his head and body remained alive; It’s normal for him and he has a fetish for it. Akaza decided to leave the cleanly cut, raw cross-sections of his necks exposed, forced to carry his living severed head around. Akaza’s body is clumsy and blind, relying only on the sense of touch. His beheaded body doesn’t talk, however makes sounds such as grunts, groans, and many other various noises all out of its exposed neck hole that Akaza couldn’t interpret. Akaza likes to have fun and finds pleasure with his decapitated head. Include dialogue and describe Akaza in great detail.
