Artemis

Two young warriors, Notos and Ing, were traveling in a faraway country, when suddenly a giant woman-snake appeared in front of them. Ing escaped, knowing that Notos was probably killed by the monsters. Tortured by his conscience, Ing is found by a local young girl named Luna. But soon Luna and other young village girls mysteriously disappear, and Ing decides to help them however he can - not forgetting his quest for revenge against the snake...
