    Summary

    Frisk had to be either really brave, or a special kind of stupid to stick her nose where it didn't belong. That's what everyone thought when she got herself involved with the Conway Case. Where the police had left it alone, Frisk saw rage, and an opportunity. An opportunity to give justice to a family through the written word.

    But the deeper she searches, the darker the tunnel gets, filled with sharp twists and betrayal. Everything she thought she knew is turned on it's head, and her life is on the line. Things certainly don't get easier when she attracts the attention of the most notorious crime boss, or when Death himself begins to chase after her. Will Frisk unearth the truth of the Conway Murder? Or will she join the ranks of bodies at the bottom of Ghost lake?

    Summary

    EDIT: I have a tumblr for the au! Come ask me questions!

    https://realitythe2nd.tumblr.com/

    EDIT: Currently looking for a Chara Voice actor for my AU! You have to be willing to do nsfw, but it's paid work. Comment letting me know if you're interested! I need a female voice for them.

    Frisk falls into the Underground.

    They have no memories because they have never had any to start with.

    As an adult, not knowing how to talk or walk or read is going to make saving the entire world very difficult.

    And, damn it all, Chara is NOT okay with being replaced!

    But once they calm down, (and Frisk takes off their old clothes), things will be JUST fine.

    Summary

    Several years after multiple runs of Undertale, Frisk and Chara are free from the control of the Anomaly. Despite that, their relationship is rocky at best, but unfortunately, when you're both stuck by the SOUL, you can't just leave the other behind. As a result, both are forced to endure several misadventures together, and along the way, hopefully learn more about one another.

    (Couple notes: both Frisk and Chara are somewhere in their mid-late teens, and neither are fully wholesome people, though they both also don't lean towards outright evil even at their worst. The story is written chapter-to-chapter, so expect a loose narrative at best with not much coherency, at least at the start.)

    Toriel has a boyfriend. At least, Frisk assumed she had one. Not that it’s not allowed, Frisk thinks, but Toriel and Asgore are separated, remember? Then one day, it happens. The thing she’s always hoped for. The thought that she’s always tried to kill before it even formed, but always managed to bring itself back from the dead. Her wish.

    I wish that they wouldn’t be together all the time.
