Gaiya is the usual fantasy world with monsters, demihumans and gods related to different mythologies and folktales. There are eight different magics each with their respectable avatar. The mere existence of the avatars has waged a war between the East and West with the sole purpose of acquiring the powers of all the avatars. As the final avatar from the Eastern Forces is slain in battle, his powers are passed on to any person suitable to be the avatar of water. This story follows Rasuku Bach, the new avatar of water. As Rasuku is a person from Earth, he has no idea about the origins or the purpose of his powers.
