in KH: Birth by sleep, to unlock the secret ending, you have to beat every characters story and find all xehanort reports, also you have to play on standard mode or higher, but I have a question. I have beaten terra's story on beginner. I'm currently playing ven's on standard then I'm gonna do Aqua's on proud. Will I be able to unlock the secret ending with just one character on proud?
i played all on critical so im not sure, but i would assume if they are all higher than standard it wouldnt matter.
