Rhao, 13 years old, is very drastic in his judgements, introverted and stubborn. In his village he feels trapped, he can’t accept the injustices his family suffers and he’s ashamed of.
That’s why he decides to leave, following Sharion, a famous “bounty hunter” and his hero. Sharion caught many outlaws, he’s incredibly skilled at fighting and flies on Mistral, a wonderful hammer shark with huge wings. Sharion is someone who prefers acting to speaking, he fights injustice and he is free. Rhao’s aim is finding this legendary man, knowing him and becoming like him!
Sharion is chasing Krisia, a mysterious witch accused of performing occult rites, sacrifices of children, murders and kidnappings. Krisia is an elusive and dangerous witch, that’s why Sharion is chasing her.

However, he doesn’t want any kid around, and roughly rejects Rhao. So the kid decides he will find Krisia before Sharion could do it! This way, he will prove him that he is not a little brat and that he’s deserving of his attention. But Rhao’s self-confidence vanishes as soon as he is badly beaten and hurt by some bandits.
Picked up and sheltered by a mysterious and charming young woman, Rhao founds himself alone again, but the angel who saved him was called Krisia: how can she be the evil witch he’s looking for? And why does Sharion chase her?
