Reincarnated as a cynic : Happiness is a Lie

Happiness is a fragile lie. Suffering is the only truth.

Fifteen-year-old Hyoko Hitabi despised his past life. He hated the shallow smiles of a hypocritical world and died with zero regrets. But fate played a twisted joke on him, and he woke up reincarnated into a brutal underworld—a literal hell governed by fearsome Demon Lords. 

To anyone else, this place is a living nightmare. To Hyoko, it is the perfect reality. 

But Hyoko isn't alone in this abyss. Sealed deep within his soul is Veldo, an ancient, legendary demon who seeks peace for humanity. Two completely opposite minds tethered to a single human vessel. One hates happiness; the other wants harmony. 

Equipped with unyielding dark magic and backed by a hidden human resistance, Hyoko sets his eyes on the absolute peak. He has no desire to become a savior, and he doesn't care about conquering kingdoms. His only objective is to butcher the supreme Demon Lords, reclaim his spot as number one, and prove that strength is the only absolute rule.

Step into the darkness. The path of the ultimate anti-hero begins now.
