Chainsaw Man: The Strange Devil in Reze's Cafe

[Chainsaw Man + Single Heroine: Reze + No System + Devil Protagonist]

The boy's real name is He Ling. When he was young, he was caught in an indiscriminate disaster. At death's door, he repeatedly knocked on its gates, only to be utterly rejected by the Grim Reaper. Death unilaterally refused to accept his soul. His wounds healed at a grotesquely rapid pace, while the pain endured forever, leaving him no escape. The endless torment of being unable to live or die gave rise to the power of the Tragic Comedy Devil, which took root within him. This power splits according to his state of mind into two completely opposing forms, physical embodiments of the kindness in his heart and his instinct for destruction. Though he is very handsome, no one dares approach him. Without his consent, anyone who comes close is overwhelmed by their own negative emotions.

With death's door closed to all things in the world, he wandered alone for years, with nowhere to call home, until he met Reze, who was working at a coffee shop on a street corner in the city.
