So it seems there are a lot of isekais recently, with a girl being reincarnated into an otome game.

We've had Bakarina, but what if she was (American) a gun nerd instead? (and also less dumb?) - This.

The MC gets reincarnated as an Antagonist of a game she played before and wants to prevent her doom. It's nothing new, but I had fun so far. You don't get real depth here either, it's just a girl with guns. And magic.

She's also very skilled at magic, but that's not really needed - she just uses magic to be better and faster at shooting guns. There are no twists here, the story is predictable and yeah...

I give it 6/10
