Slayer of the Five Leaf Clover

Born without magic in a world where magic is everything, a young boy named Asta is bullied and mocked for that very reason. In order to compensate for his inability to use magic, he started training his body at the age of 4. 2 years later, while training under the Demon Skull, Asta met an old man wearing a tengu mask. The man told him about the existence of demons and the Demon Slayer Corps, and asked if he would like to join. Asta accepted his offer, and began his journey to become a demon slayer.
