- Description from novelbuddy

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

In a world where black holes, magical talents, and formidable hunters form the fabric of everyday life, Ethan Cross—a freshly graduated student with an uncertain future—once believed he would lead an ordinary existence like everyone else. However, everything changed when he awakened a seemingly feeble and inexplicable ability known as “Coexistence with Darkness.” No one took his talent seriously—until a catastrophic dimensional rupture unleashed terrifying creatures known as the “Demons of Corruption” upon him.On the brink of death, the pendant he had inherited from his father suddenly activated, summoning three dragon girls—beings of unimaginable power, yet with complex and rebellious personalities. Cursed in the past and trapped within that pendant, these three dragons have now become inexplicably bonded to Ethan. The twist, however, is that they neither recognize him as their master nor believe he is worthy of such a union.Now, Ethan must unravel the mystery of the darkness within him, learn to control his burgeoning powers, and find a way to tame these proud dragonesses—forces that could either aid him in his quest to conquer the underworld or lead to his ultimate downfall.A power that no one had believed in has become the key to mastering the shadows. Can Ethan harness it without being consumed by the darkness?
