The story takes place in a fictional mythological world. Haya (Danny Glover) is a well-known dragon hunter in the industry. He invented the warship and is known for his brave and warlike personality. However, only Haya himself knows how much fragility and regret he hides in his heart. It turns out that Haya once caused his sister to die at the hands of the white dragon because of timidity and fear. Now, he has adopted a girl named Rachel (Sofia Pernas). Rachel's father died at the hands of Haya because he escaped in the battle. Haya concealed the fact from Rachel and lied that her father was killed by the dragon. Ismael (Corey Sevier) joined Haya's team. When he and Rachel finally went deep into the white dragon's lair, they found the body of Rachel's father with Haya's spear inserted in his body.
