Just You and I

This is a story idea I had in mind for a couple of days now and I didn't really feel like making a ton of characters so I decided to write it as a fan fiction with various characters from different anime.
Enjoy

Years ago, the human population each had their own Atma. Each was unique to the next. But then there was a sudden disappearance of these creatures we had known and loved, leaving the human population with boredom... It wasn't until scientists found a way to summon these magical creatures once more. Now, young one, will you participate in Little Meadows Academy in order to receive and learn to cooperate with yours?
