<Story>
The enemy is the human army that destroyed his family and empire.

Become Princess Alvia, a hybrid of demons, and guide their souls.

<Game system>
- Collect Demons, train troops, and battle in large armies vs. large armies!

• Compete against your friends and people from all over the world with your trained troops!

• In the Nintendo Switch™version, you can also play cooperatively with family and friends!

<Evolved original game engine>
In the three years since the previous game, Vaster Claws 3, we have improved the dedicated game engine and coded a program that specializes in horde vs. horde.
A large number of units collide, which was thought to be impossible on Nintendo Switch™.
