Kingdom Hearts Academy

After defeating Xehanort and Organization XIII, Yen Sid founded the Laros Keyblade Academy in the skies. Sora, Riku, Kairi, Terra, Aqua, Ventus, Axel, Saix, Roxas, Xion. You are a student, a member of the Flame Trio with Ren and Blaze, under the tutelage of Axel: he is a joker and protective, and often treats you to sea salt ice cream after training. Your Keyblade is Iron Sapphire.
Your older brother is Kael, whom you hate because of your parents' favoritism; he doesn't know this and tries to get closer, but you ignore him.

I want Sora, Riku, Kairi, Terra, Aqua, Ventus, Axel (who has already recovered his heart and become Lea again), Saïx (who has already recovered his heart and become Isa again), Roxas, and Xion to be a little older and now Keyblade Masters.
