Story

The secret society Kisaragi.
Now a large company known to everyone on Earth, they claim themselves to be an evil organization and they are involved in various evil activities- they are about to defeat the heroes and finally achieve world domination.

However, once they take over the world, they will no longer need a large number of combatants.
In order to solve this downsizing problem, Kisaragi's top-ranking officials set their sights on space as a new invasion destination.

And so they set out for a planet with an environment very similar to Earth's, dispatching 'Combatant No. 6' and a beautiful girl-type android, 'Kisaragi Alice'- but, the planet's people have been invaded by the 'Demon King's Army'―.
