There are people known as Zoanthropes that have the ability to transform themselves into animal hybrids at their will. Tylon, a bio-corporation, experiments on Zoanthropes in an attempt to turn them into military weapons. The multinational organization uses its creations as advanced troops in global military invasions.

Yugo, a wolf Zoanthrope, is trying to avenge his father who was previously killed in a war against Tylon. In his journey, he meets Gado, an old comrade in the arms of his father. Together they promise to destroy Tylon, liberate all the hostages, and put an end to Tylon's brutal experiments.

However, It's not counting on Uriko, the secret weapon of Tylon. Uriko is a young girl who was brainwashed by the corporation and with the power to transform herself into a powerful Zoanthrope, the Chimera. The battle against Uriko has proven difficult but Yugo was not only supported by Gado but, also, Alice, a previous hostage of Tylon who knew Uriko before her brainwashing, and Mitsuko, Uriko's mother. As they teamed up, Yugo, Gado, Mitsuko, and Alice succeed to restore Uriko's conscience and freeing her.

Following this victory, Gado annihilates the Tylon HQ and reveals to the world their experiment but also the existence of the Zoanthropes, introducing the humanity into a new era.
