Writer's Note: Hi. I'm Amaterasu of Hyrule, as you can see. This is my first fanfic, so please don't judge me too harshly. Also, I just wanted to let you know that this fanfic will not have, and will never, have swear words or adult themes, but will have violence, pain, and LOTS of confusing plot points. Just wanted to give you a heads-up.
One day, Sans was sitting at his sentry post in the forest of Snowdin. He was really tired and was just about to fall back asleep when he heard sobbing somewhere behind him. He gets up and tries to find the source of the sound. He walks into a clearing and finds a woman sitting on the ground in a ball, backed against a tree. She almost looks human, except that she has dog ears, and is wearing a kimono. "Heya. What's wrong?" Sans asks the woman. She doesn't reply, but instead retreats further into herself. "Hey, don't be sad. Whatever happened, it's over. Everything is okay now." Sans tried to comfort the woman. She muttered something inaudible. "Hey. You gonna tell me what's wrong, or are you just gonna leave me hangin'?"
"Help me. Please, help me!" She cries, louder in the second sentence.
"Um, hey. What exactly do you need me to help you with?"
"My friend was corrupted, and I can't help him because I'll be corrupted too." She tells Sans.
"Okay, then let's take you to my house. You look cold and starving, and you might want to get some meat on those bones, yeah? I'm guessing you might wanna discuss this in a better place, too?"
"Seriously?" That's how you're going to make a first impression? Wow. I can't believe what's happened to standards here."
"What? I was trying to get you to feel better. But, I guess, to each their own.
About an hour later, they were in Sans' room. They had discussed Sans' life. "So, that's the gist of it, huh? The woman stated, blank-minded and staring.
"Yep. So, how about you? First of all, I haven't asked you your name this whole time. That was a screw-up on me, wasn't it?" Sans stated, with a chuckle. The woman eventually replied, "My name is Amaterasu. But you can just call me Ammy."
"Okay, Ammy. What's up with you? Earlier, all you told me was that-"He stated questioningly, until he was interrupted by the door opening.
Papyrus walks in and says, "Sans! Have you sorted out the problem yet?" Papyrus says, "I hope so, because I have finished preparing dinner. Please, come eat."
"This spaghetti is really good, Papyrus. You've really improved at cooking." Sans says.
"What about you, Ammy?" What do you think of it?"
No response.
"Ammy?"...No response. "AMMY!?" Still, no next second, she's in the bathroom, shutting the door.
"Did she just… teleport?" Papyrus asks.
"Yes. Yes she just did." Sans answers, wide-eyed. They hear screaming coming from the bathroom and rush toward the door.
