My Sister Was Killed, I Turned into a Devil and Became the Enemy of the Whole World

The abyss invades the present world, and demons are rampant in the world. Naraku awakened SSS-level powers and could suppress thousands of demons. He thought that the good days with his sister were about to come. Unexpectedly, disaster came first. Just because a thing from the abyss attracted the covetousness of hyenas, He watched the group of people laughing wantonly, breaking all the bones in his body, and lighting a fire to devour his only home and sister... Endless regret and despair overwhelmed him, and he sat paralyzed in the abyss until a demon that could cover the sky appeared in front of him. Look at their greedy eyes. Naraku's eyes were filled with madness. "I look delicious, don't you? Do you want to eat it?" If humans cannot take revenge, then they will use their bodies to devour thousands of demons and become the most terrifying demon lord! I would rather fall into Shura Purgatory than let my enemy hang at the bottom of the abyss and suffer eternity! On that day, hundreds of demons walked at night, causing a sensation throughout the city. The enemies cried bitterly and begged for forgiveness. A pair of scarlet eyes opened in the endless, boundless poison barrier. "Never forgive!"
