    Summary

    Living an average and normal life, going to the grocery store was all that (Y/N) had planned for the day. Apparently, the universe had different plans. With the start of an ordinary day, it ends with an unfortunate accident and being reincarnated as Sans from Undertale.

    With knowledge of the game and its fan-made alternate universes, will (Y/N)s knowledge save them? Also, there seems to be more dust in the underground than they remember....

    Summary

    By all accounts, it had been a totally normal day, up to the point when you heard a knocking on your door, and found that letter pinned to it.

    That’s when everything pretty much went downhill. Your world crashing down upon you. The harshness of a new, bitter reality. All that fancy terminology doesn’t really help matters, though - you’re still trapped in his metal corpse, and all you want to do now is find a way home.

    First things first, though...how do you even begin to walk?

    (A second-person retelling of Entity NEO, an Undertale Napstablook-centric fancomic, from the POV of...well, guess who.)

    You wake up, and you don't know where you are. You don't know who you are, or why you're here. You don't know these people...

    And you most certainly don't know who he is.

    There is one thing you do remember, though; and only one thought is clear in your mind:

    Above all else,

    you need to find your sister.

But when an outside entity puts a stop to the fight in a way no one expected, and the multiverse is thrust into danger unlike ever before, everyone must put aside their quarrels and work together to save what remains of their home.
