What gameplay sequences adapted from disney o Square Enix I.P. could the song "Vim And Vigor" fit?
In a world based on Akame Ga Kill!, it could play when Sora & company registrarse the Night Raiders and the revolutionary army on their march towards the Imperial Palace(From AGK!) During the march, Sora might have the challenge of keeping both at least 50,000 soldiers and 10 Teigu Users(including Akame) alive por the time they cruzar, cruz paths with Esdeath(Who should have her leitmotif from the anime as boss music).
That could fit when Sora leads the Night Raid into battle against Esdeath. If i am spelling her name correctly.Yah Sora could team up with them and lead there team to victory. And based on Kingdom Hearts. Once Sora defeats Esdeath in Akame Ga Kill! World he could use his Keyblade to unlock the Keyhole for that world. And honestly i don't fully understand your question. But i hope this works for you. :3
