Once upon a time there was a twin-tailed sister princess who was very unfriendly.

It's a dream-like action game where you can pick up and throw anything you want, whether it's the enemy, twin tails, or super-large object X, as long as you can get on top of it. What stands in front of the main character, the younger sister princess, is the older sister princess who is angry at her younger sister's actions. A quarrel ensues between the sisters, who put the importance of the country aside.
