What happens when a medieval world of swords and steel is invaded and forcefully introduced to a System of levels and magic?

It was just another ball.Princess Cassandra thought she could deal with it. She just had to pretend for half an hour to actually care about the attending nobles before her father would let her leave, as usual.

That is, until the sky started glowing blue and strange text appears in front of her face, mentioning something about a System.

Even that she could deal with.After all, it's interesting, right?Regardless of how… bizarre… it is, it's still something new in her rather boring life.

But being kidnapped by planar invaders from some planet called Earth after a literal glowing heart flies through a portal in front of her and disappears in her chest?

That might be a little too much.

A couple of notes: Cassandra is not your typical type of princess. She is much more laidback, without much care for politics, and she is by no means spoiled. In Midgard, everyone in the three royal families all must train in combat so that they can protect their share of World Tree Sap, which grants whoever drinks it various benefits, from the monthly challengers. Lastly, the System is automatically translated to everyone in the story in a way that they will understand if they are unable to read or are blind.

PS: Yes, I know not every princess is spoiled. It's just that there are a lot of instances of there being spoiled princesses, so I thought I'd mention that.

The content warnings are mostly so that I have freedom to do that in the future chapters. I normally don't put all that much swearing into my stories, or traumatizing content.

Although there does tend to be some gore from time to time in my writing.

However, there will be no romance and no sexual content in this story.

This is my fourth series, and I hope you like it!

Also, I am open to suggestions! Feel free to leave suggestions on how to improve the story, and if I feel that they're good ones, I'll add them!
