I thought this had a nice retro feel to it.

Cayna's delight at being reborn has a much better taste to it than the majority of power-fantasy isekai. She's not trapped, she's freed, but that has made her feel a little guilty about it and uncomfortable. It's the opposite of the bitter edgelords, the revenge driven, the "Imma gonna make the best out of a bad situation by having such a 'cheat' ability," rehashed stuff we see 5 times a season.

She knows she's OP, a little cringe about the legends she's accidentally made by being in the game too much and playing it too long, but she had a good reason for being so hardcore into the game.

Like 1990s isekai and fantasy series. A little more pure-hearted, with a sense that being isekai'd isn't a reward or to make up for being hit by Truck-kun, or the "OMG, I'm trapped in my favorite game!"

It's an accident, just like the power outage that somehow sent her here.
