Equestria Girls
The newly crowned Princess Twilight arrived at the castle in the Crystal Empire for a princess summit. She is uncomfortable with her new state and her new wings. She tries to sleep and eventually succeeds. But, a mysterious mare steals her crown and runs off into a mirror. Princess Celestia reveals that it was her former student, Sunset Shimmer. She tasks Twilight to go into the mirror world to get back her crown (since it's also the most powerful Element of Harmony). Twilight and Spike goes to the mirror world. There, they realizes that they have been turn into a human and a dog respectively. Twilight ends up meeting Sunset after wandering into the Canterlot High School. The latter was bullying a human counterpart of Fluttershy. Twilight interrupts her and Sunset doesn't recognizes the princess. She talks down to her, saying that since she's new she shouldn't confront her. Twilight lears that her crown is being used as prize to the Princess Prom, and decided to compete to win it back. Sunset on the other hand has won the past three prom crowns and wasn't going to let the new girl win the very crown she needs for her plan.

Rainbow Rocks
The next time the two met they became friends, as Twilight helps Sunset fight a threat from their pony world who were formally Sirens with a singing gift and their band name is the Dazzlings. Sirens from history have caused enchanted conflicts in the pony world and Sunset noticed the anomaly while giving a school orientation to three new girls. The girls sang to the cafeteria and the human 7 witness the drastic change of the mood where negative energy filled the room and the pupils in Canterlot High were arguing. Twilight came to the human world to help sing and join the newly formed band, Rainboom. At first Sunset Shimmer was watching from the sidelines. As they realized when they associate music with pony up, Twilight kept testing for the phenomenon. The two share a moment during the sleepover at Pinkie's house.

Twilight was stressed at first to figure out the lyrics to the songs as she anticipated the battle of the bands with the Dazzling. Twilight kept trying the lyrics over and over, even when she sang appallingly at Applejack’s house at the band practice. During the elimination round, Sunset stood at the sidelines while Twilight sang as the lead. However the Dazzling confronted Sunset and caused doubt to Sunset about the friendship with the band and she has no part in the competition even when they were all qualified for the next round. The Rainbooms had their own internal conflict and when Trixie Lulamoon wanted to take revenge on the Rainbooms, so she trapped the girls backstage right before the final battle. Meanwhile with the girls trapped, the Dazzlings used their magic to mesmerize the crowd singing ‘Welcome to the Show’. Sunset realized the problem and solved it in time before Spike rescued them with DJ Pon and their internal issues were solved. As the Rainbooms entered the final battle they came up strong at first but the Dazzlings were overpowering them. That was until Twilight acknowledged Sunset to sing with the band and the Rainbooms defeated the Dazzlings with her final impromptu of their song. Meanwhile, Sunset Shimmer became more involved with the Rainbooms with not only singing but her amazing guitar skills.

Friendship Games
The event of the Friendship Games has Sunset meeting Twilight's human counterpart, who is from her rival school. Sunset knows that this second Twilight, who is nicknamed Sci-Twi, is different from the first Twilight she befriended and this why she acted cruelly towards her. After the magic Sci-Twi stole from Sunset and her friends consumes her and transform Sci-Twi into Midnight Sparkle, Sunset remembers when she went through something similar and how the power of friendship is what allowed Princess Twilight to stop her, and later offered Sunset her friendship. Since it was Princess Twilight's kindness that got Sunset to change for the better, she decides to take a page from Twilight's book by offering Sci-Twi her friendship. Princess Twilight Sparkle mainly remained in Equestria as she has princess duties to attend to.

Spring Breakdown
After Sunset finds another portal to Equestria, she takes Sci-Twi and the Rainbow Dash of the human world to see Princess Twilight, who as surprized to see them. Twilight tells Sunset and her friends stories of her resent adventures, and one of them involves her battle with the Storm King. As they talked it Twilight realized that she and her friends had accidently sent some of the King's storm magic to the human and it is endangering Sunset's classmates at this very minuet. To help the three save them, Twilight gives Sunset the staff and the anomaly of the Storm King Magic stopped. Sunset takes them to Twilight in hopes that she'll let them use the portal she has in the castle to send them all back to the safety of the school. Sunset gives a surprised Twilight an apologetic look before she asks for her help once again.

Forgotten Friendship
When Sunset's friends lost the good memories of her with her friends, she turns to Twilight for help. Sunset Shimmer wrote in her journal to Princess Twilight Sparkle asking her if she was still her friend as all her friends remembered her as the bully she used to be. Twilight brought Sunset back to castle in Equestria to see her former teacher Princess Celestia. At first, Sunset was scared that Celestia would be unforgiving but instead, she embraced Sunset in their reunion instead. The Alicorn sisters Celestia and Luna then led Twilight and Sunset to the library's restricted section to find more information about the memory stone. Shortly after, Princess Twilight Sparkle had found information about the memory stone and how it was used to erase memories of others by an enchantress but there was a section missing. Sunset suspects Luna for being the one that erased the memories of her friends but this time Twilight did not follow her to the human world after Sunset tried to tell other Human 6 everything she knew about their friendship.

Fanon
This shipping started mostly after Sunset's redemption. But because Princess Twilight started to stop appearing in the EG universe, fans quickly moved over to SciTwiShimmer, as Sunset becomes friends with Twilight's human counterpart while staying in contact with Princess Twilight through a magical message journal. Because some SciTwiShimmer fans call the said ship "SunsetSparkle" as well, it sometimes causes fans to confuse the two ships for one another, along with the fact that Sunset is close with both pony and human Twilight.

On AO3, the ship has 84 fanfics, while FanFiction.net has 49 out of 503 in its My Little Pony (cartoon) category.
