It's happening again.
An uncontrollable desire to kill and drink. It had been happening for years and years now and even a Youmu like Neil wouldn't be able to handle a temptation as strong as this one. He clutched his heart while leaning down against the walls in an alleyway. Cold sweat broke out and his breathing became more and more irregular. His eyes slowly fades in from the usual cool blue into a violent and crimson red. His senses were tingling and more and more he craves for blood.
Soon, he succumbs into the blood lust. His nose twitched as he picks up a dangerously close scent of Youmu in his area. Somewhere close to him where no other scents collide with each other. Further deep into the alleyway is where the requirements are all met. He stood up and walked into the alleyway, rats scuffling around in competitions where the victor gets its lunch. Just like the rats, Neil was about to get his. However, this one is more of a one-sided battle rather than an actual fight.
His teeth sinks into the flesh of a Youmu. It did not had a shell covering the skin, yet its flexible body made up for its lack of defense. It unfortunately, fell into the hands of Neil Yamamoto, a Youmu of Madness who consumes the blood of its own kin and of the humans. Neil had soon found human blood to be more less satisfying than his own kin. Their blood somehow tickles his body and when it flows down his palms, the warm sensation just makes it better.
He soon regains his self conscious. He stares down on the bloody mess he made himself and his hands full of the blood he had feasted upon. The body lost a limb and its head, but Neil only stared down on it like its a normal occurrence. Well, of course. To him, this sudden surge of blood lust surfaces just about once every week and it always ends up with him being covered in fresh blood.
He took off his jacket and threw it on the ground. He turned it inside out and worn it again, before departing off the alleyway casually.
