Sekai ni Hitori, Zenzokusei Mahou no Tsukaite

Zenichi Kiyama was an ordinary, unassuming office worker whose life came to an abrupt end following a tragic traffic accident. However, death was not the end of his story. He soon found himself reincarnated as a newborn baby in an unfamiliar fantasy world, one where individuals are defined by a concept known as "perfect compatibility." Thrust into this strange new reality with the retained memories of his past life, Zenichi must navigate the complexities of a society governed by magical aptitudes and rigid classifications. As he grows, the time comes for his innate magical abilities to be formally evaluated. In this world, attribute appraisals are conducted using a specialized crystal designed to reveal a person's true elemental affinity. When Zenichi undergoes the test, the crystal reacts in a way no one anticipated, displaying a single, ominous result: the dark attribute. This revelation sends shockwaves through those around him, as possessing such a trait carries devastating implications. Rather than being celebrated for his unique compatibility, Zenichi is immediately branded with the worst possible stigma—labeled a demon child. Now, he must face the harsh prejudice of a world that fears his very existence, struggling to survive and uncover the true nature of his power while bearing a title that marks him as an outcast.
