    Summary

    So when I finished this amazing anime called Magical Girl Spec-Ops Asuka

    I had a thought that was boiling in my mind of how that could work.
    Which in Undertale the scene of Undyne saying that anime is real question came to mind.
    I was like well eeehhh heck why not lol

    So I was thinking to make Alphys and Undyne theory true in this Fanfic of this character got sucked into
    Their world when a the multi dimensional being magical girl caused a rip portal when she was battling.

    Yea ill roll with that XD

    Summary

    Frisk and the main group are confused as to why the game doesn't seem to be working as usual; there are no more save points and time seems to be flowing in an entirely new direction. But what's stranger, the citizens of the Underground are befuddled by the introduction of new monsters; from the surface at that!

    But how did that come to be, and more importantly, how can these new violence-hardened criminals be of use to a dying timeline that's destined for desertion?

    As the title suggest. There's not any rules to be honest, just no smut. If you are triggered by anything at all, check the warnings. They will be put in the notes before each chapter.

    Summary

    Takes place concurrently with Flowey the Flower, Agent of Chaos. However you can read this one first, it will still make sense.

    Frisk's parents work at the SCP Foundation. His father is probably dead and his mother is more interested in the SCP object she studies than in her own son. When a large containment breach takes place, Frisk takes advantage of the chaos to make a break for it. He probably should have stayed away from that anomalous mountain though...
