Alison Brie and Gillian Jacobs as Annie and Britta.
Britta and Annie, although friends, are initially not as close to each other as they are with other members of the study group. The relationship between the two women fluctuated over the years resulting in some differing extremes. Most of the time they had an almost sisterly friendship where they support and are protective of each other. However, there were a few occasions that feelings of jealousy between the pair arose which have lent a more adversarial nature to their interactions. These conflicts occurred mostly due to their seemingly similar taste in men, particularly Vaughn and Jeff. Recently they have since moved past all these issues and formed a more solid friendship. Annie has even been instrumental in helping Britta in her budding relationship with Troy. Britta is portrayed by Gillian Jacobs and Annie is portrayed by Alison Brie. They both first appeared in the Season One episode "Pilot".
In their first year at Greednale, Britta Perry and Annie Edison learned about a Spanish study group and decided to attend. It was discovered that the study group was just a ruse set up by their classmate Jeff Winger to woo Britta. He hadn't anticipated Annie and several other classmates would show up as well. After a failed attempt to continue the group without Jeff, they found him depressed on the steps of the library. Annie took pity on him and convinced Britta to allow Jeff to rejoin the group. Annie and another study group member Shirley were impressed with Britta's social activism and asked her advice on how to stage a political protest on campus. When Annie has trouble getting her crush Troy Barnes to notice her, Britta comforts her in the Woman's restroom. After Winter break, the study group deals with a student named Buddy who wants to join them. He tells them about daydream he had where Britta and Annie wore cheerleader outfits and fought in bubble bath. When Annie takes an interest in Vaughn Miller, she asks Britta for her permission since Vaughn had dated her briefly. Although she claimed not to have a problem with them dating Britta conspired with Jeff to break Vaughn and Annie up. Ultimately Britta realized Annie and Vaughn really liked each other and gave them her blessing. Annie herself experiences some jealousy after witnessing Troy and Britta perform a sensual dance on stage at a recital the study group attended. When a Paintball Assassin contest is held on campus Britta, Annie and Shirley team up to take down the competition.

In their second year at school together, Britta and Annie are forced to deal with their actions at the Tranny Dance. Annie learns Britta slept with Jeff during paintball the previous school year while Britta learns Annie kissed Jeff outside the Tranny Dance. They attempt to put aside their differences by working on a fund raising campaign together. However, the issues between them erupted and they had an embarrassing physical altercation on the campus quad. Along with Shirley and Abed they take a women's studies course and run afoul of a "Mean Girl" clique led by a student named Meghan. When Annie's pen goes missing in the study room, Britta accused Annie herself of taking it. Later, Britta became friends with a classmate named Page whom she thinks is gay but Annie learns otherwise. Annie withheld that information due to Britta obnoxiously touting her friendship with Page as a sign of her own progressiveness. Their friendship was strained again when Abed figured out Jeff and Britta had been secretly hooking up throughout the year.
I need to stay with you this weekend. Not just stay with you, I need to be on lockdown. You were a pill head, so think of Blade as Adderall. And handcuff me to the radiator like a mother-flipping carny-banging werewolf!
At the start of the study group's third year at school, Britta and Annie helped Troy console Abed when his favorite TV show was put on hiatus. Britta declared Psychology as her major much to the amusement of Annie and the rest of the group. Britta and Annie showed up together at a housewarming party Troy and Abed were thriving at their new apartment. On Halloween, Jeff and Britta encouraged the study group to tell horror stories in order to determine which one of them could be psychologically unbalanced.

Later, Britta and the rest of the study group helped Annie pack up her apartment after she accepted Abed's offer to move in with him and Troy.

In the morning, Britta would exit Troy's bedroom through his window, climb out to the fire escape and make her way to Annie's bedroom. Once inside she would finish getting dressed and Annie would have her a curling iron ready to go. The daily routine ended after Abed revealed he already knew Troy and Britta were hooking up. Annie and Britta accompany Troy, Abed and Jeff to an Inspector Spacetime convention. Britta turned to Annie for support when Abed declared her opinion on "Inspector Spacetime" to be invalid. Annie refused to back Britta up unwilling to upset Abed and walked off. Britta and Annie dress up in traditional Oktoberfest barmaids as part of an elaborate ruse to trick the same German exchange students from their previous year. Months later, both Annie and Shirley reminded Troy and Britta about the upcoming anniversary of their first date. Afterwards Annie asked Britta how the date went unaware that Troy and her broke up.
After the study group graduated, Annie and Britta returned to Greendale when Abed told them Jeff had come back and was forming a "Save Greendale Committee". The rest of the group re-enrolled when Abed accepted a teaching position at school. Britta hoped to obtain a degree in Psychology while Annie decided to pursue a degree in Forensics.

In Britta and Annie's sixth year at school, an overlooked task by the Save Greendale Committee resulted in a disastrous outcome. Britta and Annie initially disliked the consultant Frankie Dart that Dean Pelton hired to run the committee. Eventually they accepted her and inventor Elroy Patashnik into the group. Britta was homeless at the time and accepted an offer from Annie and Abed to move into their apartment. She was infuriated that her parents George and Deb Perry orchestrated the arrangement. Britta ultimately made peace with the arrangement but tested Annie's apartment rules when she threw a large party at her new home. When a hacker threatened to expose sensitive school information, Britta convinced the committee to not give into his demands. Britta and Annie regretted this after the hacker released their personal emails to the public. Britta and Annie have an awkward lunch with Frankie before attending the wedding of Garrett and Stacy with the rest of the committee. Britta and Annie's arrival with the group creates a spectacle at the event. Their attempts to improve their behaviour at the reception results in a worse situation unfolding. At the end of the semester she and the committee imagine what next year might be like. While Britta stays behind at Greendale, Annie leaves for the summer to accept a F.B.I. internship.
