Ys vs. Sora no Kiseki - Alternative Saga

[mister seta 123]

Oops, I've encountered with a problem. On Adol's campaign, when you start with the third battle, (it doesn't matter which one do you choose first, the third will trigger the problem) I think they talk about Support Characters and the Stamina.
The background for that tutorial is a white screen, and when the battle starts, that white screen remains there.

However, if you exit and return to map, that tutorial isn't explained again, and the fight is shown. I'll let some pictures and a log, if there's something strange.
