    Summary

    When did life start going downhill?

    Error couldn’t answer. He didn’t see his path as something to climb, which meant that there couldn’t be a slope going downhill. He saw life as black and straight, running across the blank emptiness of the Void. No rising, no falling. Just a sequence of events that leaves new scars on bones. Endless battles on the way to the outcome — routine. Madness — the truth of life.
    Not to mention this pregnancy — unwanted, hateful and painful.

    Summary

    When you had woken up in the middle of the night to pitch black, you had suspected that Grillby was having insomnia again and had gotten up to get booze. You never expected him to be in the middle of a “private meeting” between dangerous past rivals.

    When they find out there’s more at stake than they first realised, they don’t hesitate to take what’s not theirs and suddenly, you’re seeing pitch black all over again.

    However, the person who can help you has been beaten, tortured and brainwashed into believing you’re the cause of it all.

    Summary

    You're new to Ebott--the town of monsters and magic, as presented by their tourism board. Life is difficult enough switching schools as an incoming sophomore, but maintaining friendships with people straight out of a fantasy book? That might be a challenge, but it's one you're trying your best to take on.
    In which the reader is NOT the focus of the story, but a new member in a web of politics, drama, and high school shenanigans involving the Undertale kids.

    In a world were monsters are forced into slavery and are controlled by collars around their neck, you never thought you'd be a part of the twisted reality. Your sick and owning a monster was the only way to keep you alive just that little bit longer. You hate the idea, Your Dad hates the idea, but it is the reality you know have to live with. It does help a bit to know that the monster your stuck with hates the human race and has no qualms about you dying. You do wish he'd stop spoiling your TV shows but it's not like your going to order him not to.
