Whistle of Chaos

At the end of the Earth's destruction in 2368, researchers who managed to create a spaceship and artificial intelligence called Defender, set out on a journey to find a new habitable planet. Then managed to find a planet that has a very large photon power, namely Planet Veda. In order to create peace, the Defenders and Veda formed a space fleet, namely Whistle.

To protect Whistle from the attacks of dark creatures named Vedarios and Dolls, Veda creates special artificial intelligence called Returners namely Sachi and Navile. Their mission is to protect the Defender, Whistle, as well as the power of the Vedas. Together with the other Defenders, they began to explore space to find other planets.

However, repeated attacks from a group of dark creatures called Dolls and Zero's organization put the Whistle Fleet at risk. Can Naville and Sachi protect them all?
