[Crossover] The 2D World Conquest Plan

Su Su said,

She and the person she loves are separated by a dimensional wall.

The wall is thin, but she can never break through it.

On her fifteenth birthday, the wish she made was:

"Two-dimensional world, please take me in!

I'm begging you..."

The two-dimensional world is where my heart belongs.

The premise might be a little far-fetched, so don't mind that.
