- Description from Novelupdates

Having spent her childhood confined in chains, Alice was a child who knew neither love nor joy. Scorned by her family while being tortured in the name of the greater good for years, she grew numb to all feeling and thought. That is, until one day, a man in black offered her a chance to escape.There were once rumours widespread of an endless hell, a land of glorious death and dreadful opportunity. Fools went in search of it, and the clever never ventured into it. Only when its baleful mysteries spilled unto the earth did all hear its name — the Abyss.A single drop of its blood could give someone the power to control shadows, move faster than sound, or strength greater than the strongest man. Yet, it all came at a cost; the blood would always make sure those who consumed it became part of the Abyss, with one exception — Alice. Cast away by her own blood, it was her destiny to rot in a gilded cage.But, that fateful day changed everything. Gifted a second chance at life, a chance to turn her life around and claim vengeance against her family, a chance to dive deep into the Abyss and gain the power to govern her own fate, Alice took his hand, unaware of the destiny unfolding before her.

Throughout this current life of mine, I will pay no attention to my past lives, nor will I seek future lives. I wish to live vigorously, to pay back debt of gratitude and fulfill duty to avenge, to defeat valiant heroes from all species, and to proudly laugh at all the Gods and Demons of the Six Path of Reincarnation!
