The casts of all five main Persona games get into a giant Rumble. Each team fights the other League style, with the one taking the majority wins as the victor.
1) Characters without Persona's and their standard melee equipment. No projectiles weapons like guns or arrows.
2) Characters with their best Personas. (In the case of variable persona's this is the strongest persona that thematically fits the character storywise, ie, the P3 Protagonist gets the "Messiah" Persona.)
