This Heartless World

Once upon a time, there was a miserable girl. She got transported to another world.

Then she went on to cause a whole series of miserable, infuriating disasters.

So after being transported, she wasn't just miserable anymore.

She evolved.

She became a miserable, infuriating menace!

Thanks to some technology that can't be discussed,

this awful girl gained another powerful skill on top of being miserable and infuriating.

That skill was ball pain.

Literal ball pain.
