The forgotten Fire Clan lived an ordinary life in the mountains. When the young Fire Clan boy returned from an outing, he found that he was the only one left in the village. Everyone was bitten to death by unknown things, but his sister's body could not be found. In a panic, he accidentally discovered the magic sword that had been passed down by the family for generations. Because he was afraid of the power of the magic sword, he refused to exchange his body for power and buried the magic sword deep in the ground. It turns out that the magic sword always appears next to him. After discovering that his blood can defeat the mutated ghosts, and the magic sword always devours the people around him, he has no choice but to take the magic sword and start his own road to find his sister for revenge.
