After getting her gift, she realizes that she's overdue for the concert and gets there quickly. She returns to Alphys' lab untouched, albeit her left eye. Undyne isn't too happy over his appearance, but is knocked out by Sans before she can make a move. Gaster welcomes her and tells her that they have a gift for her.

As the move along, Undyne tags a post station, and by opening it, she actually enters the Void. Alphys comes in and tells her to tag along to her lab to get her gift. In Undyne and Papyrus' house, Undyne is practicing for the concert tonight, and Papyrus remind her that she's been practicing all night. Sans wants to stop her, but Gaster reminds him that he can't exit the void and that someone has to enter the void itself. In the Void, Sans and Gaster talk about the genocide run, and how the feeling of it has returned. Scarf Mouse then warns the group that a construction worker disappeared in the CORE, and that no one knew where they went. Nacarat Jester tells all of them that none of the humans remembers that they exist at all, and leaves Brown Bears unknowingly tells him that his girlfriend left him. Another incident as told by Ice Bear tells that a girl in Hotland also left, and has acted weird before that. Ice Cube tells all of them that no one understands why these people are disappearing out of nowhere. Rabbit doesn't know if this was the first disappearance in Waterfall, but Brown Bear tells him of another incident: a child selling umbrellas also vanished. The Librarian tells Brown Bear that a monster from Waterfall disappeared all the sudden. Monsters all over Snowdin all talk about how some monsters are mysteriously disappearing for some reason.

As it turns out, Undyne took the place of Papyrus' brother Sans, because of an incident where Sans absorbed all of the human souls, used it on the human, and quickly vanished into the void. The AU revolves around Undyne, as she figures out strange things are happening around her. Othertale is an AU created by super youmna on YouTube. You can help Undertale AU Wiki by expanding it.
