Stuck at Noire's Story (First Dungeon)

[Miight]

Well, the issue is that I'm stuck in the dungeon with low HP (110 or so) and I keep being killed by the boss after the cutscene. I'm talking about the turtle one.
I do not have any healing items anymore, and I overwrote my previous save with this one since I'm a ♥♥♥♥♥♥.
I can't leave the dungeon either.
I don't really want to restart the game, anyone got suggestions ?

EDIT : I filled and sent the Support Form from IF. I don't know if this will be resolved so I'll let this topic alive.

Yeah kind of a bad design choice in that part of the game. Your choice is to either level up somehow, restart from the start or cheat using a program like Cheat Engine and turn it off after you beat the boss.

You're screwed as this was an issue from way back. The only way out is OP DLC gear or starting from scratch or cheating as pointed out above

Exactly the same problem here. You do not have to restart the game. You can download Megadimension Neptunia VII v1.0 Plus 20 Trainer. (google it) You have to unzip it and use password "trainer". Run the file and the game simultaneously and then defeat the boss. Afterwards disable it if you do not want to use cheats.
