My Sister Was Killed and I Stopped Being a Human Being.

[Crazy world, crazy people, dark currents, extremely perverted revenge, no longer a human being] My sister, who had disappeared for three days, was already lying in the morgue of the hospital when she was found. The pain and panic before her death were still on her face. That day, the murderer who killed his sister arrogantly broke into his home, broke his limbs, and burned him and his home together with a fire. That day, and in the fire, he was reborn again. "Congratulations on gaining the power of instant death. You can kill everything you see." … "If I can't avenge myself as a human being, then I won't be a human being anymore." "A tooth for a tooth, an eye for an eye, whoever killed my sister must pay the price." From that day on, the most evil demon appeared in the world.
