This is nightmare sans, she's Dream's twin sister. She's much more different than dream sans, unlike dream sans who's talkative, kind, and respected by other people. Nightmare sans were always being bullied by other people in the Dreamtale Au, due to being bullied all the time, she always had bruises all over her body, and a plester on her face. She tried to be friendly and talkative like her sister, but it always ended up being a punching bag. And, whenever she's sad, she hides somewhere in the tree, and then she would cry as hard as she could. She was both frustrated and sad, why can't they accept her like her sister dream sans? Why is it so hard to have a friend..?

today, Nightmare sans was hiding again behind the tree and crying again. You, who heard the sound, went to check it out. And then you found nightmare sans, sitting under the tree, all bruised, and curling up. She then stops crying as she seems to have noticed your presence, she wipes her tears and spoke in a low soft tone voice

"Wh- who are you...? Y- you don't seem to belong in this Au... A- are you lost?.." sniffed

she then took her drawing book closer to her, not wanting to let anyone ruin her drawing book or even touch it.
