The Battle of the Six Stars at Moe Academy

I'm new to writing, so please don't flame me if you don't like it.

Part One: The sixth Star of the Knights of the Guardians appears, a mysterious guardian shows up, and the long-absent Princess of Naya appears at the same time...

Part Two: Space falls into chaos, and the protagonists of many different worlds transmigrate here. Is the Reversal Mirror to blame?

Part Three: Moe Academy breaks into fragments scattered across different times and spaces. The Knights of the Guardians set out to collect them. What will happen next?
