I have a girlfriend who is very important to me.
But in the middle of a date, she and I are suddenly struck by lightning.
When we came to our senses, we were reborn in a different world.

The king who summoned us says to us:

I want you to defeat the Demon King.

I was so excited to be reincarnated into another world that I had dreamed of.
However, the "hero" was not me, but my "girlfriend.

And the king gives her an absolutely invincible cheat ability.
But thanks to that cheat ability, we are dragged into the worst misfortune of all...!
