This is a well-known feature of the game: in fact, it shows that in the world of Celica there are some details to take into account: monsters sometimes do not forgive mistakes.
So if you encounter this situation often. That:
1. Make a save before battles.
2. Also analyze the type of opponent and methods to defeat them quickly. If you are tired of Celica's close relationships with monsters, then this can be turned off in the settings.
3. If you still made a mistake and your opponents began to mock Celica cyclically, return to the last save.
