Undertale: Nightmare

It's been 4 years since Frisk destroyed the barrier and monsters & humans have been living in harmony upon the surface... sort of.
As Frisk lives her normal day-to-day life, an unexpected calamity threatens to end everything. Helpless, even with her DETERMINATION, is still unable to stop this all by herself.
She'll need to call the help of an old friend to help fight.
But will it be enough?

P.S. --- Frans is hinted at in this, so if you don't like, don't think about it to much.
It's not entirely obvious (except the prologue) and doesn't really go anywhere, so you could just think that they're REALLY good friends.
But I'm still gonna be hinting at it. (⁠◠⁠‿⁠◕⁠) #Shipper
