Eri was 3 years old when the gem of creativity and intelligence was planted inside her. Her mother seemed happy but her mother was not given a gem so she was jealous. "You should have been cursed! Like me!" Her mother shouted in the car. Eri was confused. Most of her life with her true mother was horrible. One day her father gave her to another family when his wife told him she was going to kill Eri for her gems.

Eri was 7 when her adoptive father went to the geode war. She was frightened and her older brother was the only thing keeping her safe when there mother was gone. They were hungry and tired. And the war countiuned for 2 years. Her brother was 16 and was sent out to Battle. Eri was confused she thought you had to be 18 to fight in a battlefield! Her brother died from a shot to the head 3 weeks after her 10th birthday. And she helped the gems (The side she was on) win the war with her quick thinking and creative weapons.

Eri was 14 when her adoptive mother died from a terrible virus (The lightning virus) and her father was having trouble keeping the family alive. Eri was frightened when a richer family came to raise her. 4 months later her father committed suicide. Eri was heartbroken and her older sister made it worse with all of the picking on her and bullying. Eri was frightened and confused. Until Mia (Her best friend) helped her out of that situation and Eri got to live with her for 2 years and found her real father and got to live with him!

Eri was 17 when she heard of the humans against monster war 24000 miles away! She wanted to help but that would've been impossible. She instead sent food and clean water to the monsters weekly. When she heard they lost they also through all the gem people in a mountain (Mount Royal) to.

Eri was 20 when the geodes got the gems out of mount royal. In return we gave them some of our reasuch. Eri's reasurch was really important. She found out the secrets to portals and how criminal minds work and how they plan. She continued her reasurch (So did everyone else) and figured out how the gems get there power!

Eri was 22 when a accident ruined the gems. Eri was used in a experiment and she was turned into a 7 year old! The scientists did not know how to turn her back so they kept her in the lab. One day 3 weeks after the experiment failed she was kiddnaped by Killer!sans. He thought he would get some knowledge out of her but to his disappointment Eri had forgotten everything (She thought she was a orphan) before she was turned. Killer had no use for her but Swap!sans insisted on keeping her (He thought she was a monster cause of her gems) and Ink!sans and Dream!sans couldn't do anything to get him to put her back in the lab. Eri has no clue what was going on so she just rolled with it.

Eri is now 8 again. Nothing has happened. She has been living through it all. She remembers everything sad that ever happened to her. She found out her music is the strongest when she plays music (Mainly her flute). She is now known as the only human like creature to live in the sans house (In this universe). Eri has almost died. But she is always bubbly and happy (Mainly cause she lives with Swap). Eri has lived. Died. and was reborn. Eri had nothing to do with being a sans! She doesn't even have a sibling but she still is called a sans by swap.

(Authers note) Hi! Thanks for reading this story! Eri is my OC I made a long way back when I was just starting to become a fan in the undertale world. She started out as Erin but then I changed her to Eri. This is a make believe story and isn't my last version of her! I hope everyone can enjoy drawing, writing, and creating OC's and other stuff! Bunny out!

I do not own Killer!sans, Ink!sans, Swap!sans, or Dream!sans. They all belong to there respective creators. Even if I don't know those creators names!
