Plot[]
Kurumi Killer[]
Ai and her friends make their debut when they see Tohka looking sad and lonely over Shido not being around. To cheer her up, they offer Tohka the aquarium tickets that she would later use on her date with Shido. During Shido's date with Kurumi, Ai and her friends try to chase them down, but they are distracted by Yoshino.
Yamai Tempest[]
After Ellen takes a picture of Tohka, Origami, and Shido, Ai and her friends appear next to Ellen and compliment her camera skills. Then, after the airplane takes flight, they still follow Ellen while she is spying on the <Princess>. Later on, Ai and her friends enter the public bath, where they spot Tohka. While they approach her, Tohka acts in a bizarre fashion in order to cover Shido, who is hiding behind her. However, the trio's continual advancement towards Tohka's location causes the latter to accidentally push Shido off the cliff and into the sea.
Later that night, the trio end up sharing the same room with Kaguya and Tohka. They collectively start fawning over Kaguya's cute appearance and offer her some Pokey. After everyone is present, they engage in a pillow fight, which Ellen accidentally gets caught in the crossfire.
The next day, they call for Ellen to take a picture of them, while they were at the beach. As Ellen tries to refuse, Ai and her friends eventually manage to persuade her to join in on the fun. They end up burying Ellen with sand right alongside Hiroto Tonomachi, which causes the former to freak out. Later that night, Ellen trips and is caught in one of the holes they dug while speed digging, preventing the AST Wizard from further pursuing Shido and Tohka.
Miku Lily[]
At the gymnasium of Raizen High School, Ai gives a passionate speech about how they have overcome their previous failure to win the Tengu festival and will surely seize victory this year. After seeing how Shido is able to attract the attention of Tohka, Origami, and the Yamai Sisters, she and her friends push forward Shido's nomination of being the executive member for the Tengu festival.
After Shido is forced to crossdress as Shiori, Ai gets mad at Shido for forcing his duties as the executive member onto Shiori. Later, in the room, they discuss the loss of potential band members because of Ai's selfishness. Seeing Shido, Origami, and Tohka in the hallway, she orders her friends to capture them. Ultimately, the missing band member slots are replaced by Tohka and Origami. They also introduce the instruments that they will be playing, with Ai using a bass. After hearing that the drums are already taken, Tohka starts being upset, so Ai cheers her up by stating that she will give her the most sacred instrument: the tambourine
The trio also participates in the maid cafe, which attracts plenty of customers. However, before the audition started, Miku had already brainwashed them so that they would not participate in Shido's group.
Miku Truth[]
After the conflict at the music stage, Ai and her friends end up becoming maids for Miku, who asks them for information about Shido's whereabouts. Right afterwards, they barge in on Miku fawning over the new Spirits she has acquired and tell the idol that Shido has come to them instead. Later on, Miku asks Ai and her friends about Shido's relationship to Tohka. At first, they answer by telling Miku to not worry about Shido, since he is a frivolous person. However, Miku soon tells them that she hates girls who lie. As a result, they tell Miku the truth and say that they really don't know much about the two, but they do seem to be close.
Natsumi Search[]
When Natsumi is disguised as Shido, Ai and her friends believe Shido is groping Tohka. The group angrily confronts Shido for being indecent. However, Natsumi, still disguised as Shido, instead began to flirt with Ai and even asks if he should kiss her. Shocked at the action, Mai and Mii are too startled to give an immediate response. Ai, however, says that she still has feelings for Kashiwada. Natsumi then gets closer to Ai's ear and blows into it softly, which causes her to collapse.
Later on, when the real Shido came to class, the trio is ready to take revenge on for everything Natsumi framed him for, including making Tohka cry. The trio grabs Tohka away and scold Shido for his actions. When Origami recounts what Shido did (and desiring Shido to do the same thing to her), the trio blushes as a confused Shido escapes from the classroom.
Much later on, Shido (under Reine's instructions) tries to arrange a date with Ai; but instead, Mai and Mii arrive as well. The two then tell Shido that he already has Tohka and how Ai is in love with Kashiwada. The trio then begin to discuss and gossip more on Shido's relations with so many girls, with Shido only able to try to deny their accusations. In the end, the trio are captured by Natsumi, but they are set free after Shido wins Natsumi's game of spot the imposter.
Natsumi Change[]
After being freed by Natsumi, Ai and her friends notice Tonomachi discussing with Shido about their disappearance and they briefly believed that they were chosen Sentai Rangers and wanted to "destroy the obscene monster" Shido. When Tonomachi remarks how Shido touched his thigh before, the trio believe that Shido was also gay and try to get their fujoshi classmate to "update" on his status.
Before anything could more could proceed, homeroom begins with "children" coming to visit Shido. Ai and her friends notice them and believe Origami's lies which worsen the situation. This causes an uproar that is made even worse when Natsumi undresses Tohka. The trio begin to call Shido a lolicon. Natsumi then uses her powers to make it seem Shido stripped them along with Tamae, forcing Shido to escape.
Itsuka Disaster[]
When Shido is losing control of his powers, he accidentally runs into the trio again. Due to him being semi-conscious, Shido makes the decision to flirt with them to make the trio fall in love with him. As a result, their impression towards Shido has worsened due to these actions.
Nia Creation[]
When Shido is eased to his condition, Reine tells him to inform Ai, Mai, and Mii that he was just joking with them when he was flirting. Later on, Tohka invites them to Shido's Doujinshi booth in order to help out with sales. The trio purchase the doujinshi, but they still do so while regarding Shido as a dangerous playboy.
Mukuro Planet[]
At the start of the new semester, the trio is gossiping to each other. During homeroom, they see Tamae depressed over finally reaching 30 years of age and still not finding a husband. Ai tries to calm her down, but Tamae replies that she would want to make a deal with the devil for a meteor to destroy the world.
Coincidentally, due to Mukuro's actions, meteors did indeed fall onto the school grounds, causing the class to see their teacher as someone who actually made a deal with the devil.
Mukuro Family[]
When Mukuro sealed everyone's memories of him, Shido comes to class and asks Ai, Mai and Mii if they remembered him. However, the trio believes that Shido was trying to woo them.
Kurumi Refrain[]
During Valentine's Day, Ai, Mai and Mii cure the jealous fury of their male classmates by distributing obligatory chocolates.
Kurumi Ragnarok[]
On the morning of February 20th, Ai, Mai and Mii pass by Tonomachi on the way to school, who isn't dressed appropriately for the occasion. They inform Tonomachi of the rumor that Shido added another girl to his "zoo". Just as they finish talking, a Spacequake alarm sounds, forcing them to take shelter.
Mio Game Over[]
Moments after Mio is awakened, Shido is teleported away, finding himself inside the Spacequake shelter that Ai, Mai, Mii, Tonomachi and Tamae took refuge in. Noticing the absence of Tohka and Origami from their class, the trio agree to let Shido go. They restrain Tamae to prevent her from stopping Shido.
Mio True End[]
In the new timeline, Ai, Mai, Mii, Tonomachi and their teacher Tamae are cornered in their Raizen High School classroom by Bandersnatch units deployed by Isaac Westcott. Fortunately, Tohka arrives in time to save them.
