Yui Morisaki is just a regular girl, busy with her regular everyday life like the Karate Club and an unrequited love... until one day she meets a little robot named Polka! Suddenly, she's granted the ability to transform into Radiant Princess Poni Ceres, just in time to fight against the evil forces of Zydarg, an alien organization hellbent on invading and enslaving all of humankind.
Fast forward a few months and Yui is coming to grips with her new life, though her heroic activities are starting to affect her grades. But just as she's getting used to dealing with the enemy's regular troops, it seems like Zydarg is escalating the conflict and attacking with monsters. It's time for Poni Ceres to up her game too!
Fight through hordes of troopers and supernatural foes to thwart the evil plans of Zydarg, then face the monsters and generals that lead them in battles of both wits and brawn. Keep your eyes peeled for hints about the weakness of every boss...
But there's more than just fighting! Explore vast and intricate town maps to find upgrades, unlock secret scenes and side quests, and uncover more mysteries!
Want an optional dungeon full of rewards? Just head to the nearest manhole and start exploring! Beware of the mean zyborgs infesting the sewers though!
Combat & Strategy
There's a lot of combat in Poni Ceres, but brute force is not always the answer. A good strategy will get you out of the nastiest situations, including bosses, and you'll have plenty of time to prepare by learning new skills, stocking up on items, or grow stronger.
A Sprawling City
The Zydarg threat is vast, and so is the city Yui is trying to defend. Explore layered maps full of secrets to find and hidden trooper hideouts to bust... And if that's not your thing, then just bypass them and head straight to your current goal! No one's stopping you from charging right in.
In-game Rewards and Hints
Every little secret or interaction hides a reward. Redeem Small Coins scattered throughout the city for meaningful prizes, or find hidden chests full of permanent upgrades. Wait, is that a clown in that hidden room off to the side...? Don't lose track of any content with the built-in hints and achievements system.
