Sekai ni Hitori, Zenzokusei Mahou no Tsukaite

Zenichi Kiyama, an ordinary salaryman, found himself reborn as an infant in a strange new realm following a tragic car crash. This world, known for its “perfect compatibility” system, promised great potential for its inhabitants. Yet when his magical aptitude was tested using the sacred crystal, the shocking revelation came—his alignment belonged to the forbidden dark attribute. Branded as a cursed child with demonic blood, Zenichi now faces a life of persecution and fear. The very system meant to guide souls had marked him as an outcast. His journey begins in shadows, where survival means embracing powers others shun. Society whispers about the ominous boy, unaware of the destiny unfolding before them. Will this dark magic become his downfall or his greatest weapon? The path ahead twists with danger and uncertainty, challenging everything he once believed about right and wrong. In this land of light and purity, the tainted child must carve his own fate.
