KH3D Facing the final boss again (minor spoilers)

[mfampait 49]

I've already completed the game on standard mode and now I've done all of the stuff that you need to do in order to get the secret ending, I tried just answering the questions and collecting the secret message in theater mode but it didn't work so I figured that I have to beat the final boss again, but every time that I try to go past memories skyscraper riku drops for no reason

Never mind, in immortal words of Beat "I gots this yo"
