A witch boy is neither human nor divine, neither male nor female.
The blacksmith is the person who forges the magical sword that can double the power of the wizard boy. He and the wizard boy have a brotherhood that transcends blood.
He is a rare witch boy who only exists in two thousand years. He is an ordinary college student with the closest blood relationship to the forger of the Excalibur.
He has a cold nature and doesn't like to get close to others. He is gentle and tolerant, and occasionally a little off-kilter.
Such two people come together because of fate. Is it friendship that is entangled between them? Or love? Or something else?
