I just finished Chapter 3. Holy shit that came out of nowhere, it's bad enough that the fight happens right after Tenna, but starting with no heals and no save points in-between is extreme.

It's late already so I'm replaying it tomorrow, I assume I need to beat both stages with S-Rank in order to fight the superboss, and there was a secret puzzle I couldn't do anything in, so I'll look into it further.
