Plot wise it's likely Aura will be stuck with all of the curses she accumulates until you beat the game. It's possible that Aura could run into a person with a unique ability to suppress the curses or something. The quest where Aura receives a minor curse while rescuing a merchant goes into more detail about the semi-permanent curses in case you're curious.
It seems like the game is more hardcore if I choose slut scenes in the game but it's boring without these scenes.
It's like avoiding some main content in the game.
I find "Lona RPG" to be an easier game than "S.K. Aura"
because I won Lona just by grinding and spending endless time on it,
but I got stuck for the third time in Aura and want to start the game again and try to avoid any slut events.
I keep lowering the difficulty level each time, and now I've reached the humiliating Explorer mode
because I hate critical game over timers in games. :'(
There's no way to reduce Corruption Points indefinitely.
There's no time for neverending grind as I like in Dark Souls and Lona RPG hardcore type games on Normal difficulty.
But still I like Aura the game concept and rich level design of the game.
PS "Aura" the game has really top of Level Design of all H-games, I think. It's so fun to explore new locations.
