Aroma then announces her purpose for scaring the two managers of their respective units - to fill their remaining three spots for their team: Aromageddon. Aiming for Laala, Dorothy, and Shion, she decides to talk to Laala first in private. Luring her away from her friends, she and Mikan tell her why they want her, and why she should be on their team.

After Mirie gets a call from Laala about her show, she tells Mirie to lie about the present running away. The day of the concert, while Mirie runs after her wayward present again, Aroma admits to being confused about the box being empty when she put the frog inside.

Aroma is once again consulting her Book of Darkness at the beginning of this episode, determinedly searching for a strategy to win, while Mikan is oblivious...as always. After giving Mikan the order to run, she watches smugly from the sidelines as Mikan effortlessly overcomes obstacle after obstacle. Aroma's plan goes well until the limbo challenge, where Mikan springs over the limbo rod, and messes up their score, to which Aroma glares furiously. Finally, at the final challenge, Aroma is visibly unhappy at the fact that she has to exert herself along with Mikan, who basically drags her all the way to the finish line, until Aroma collapses and curses the other teams. After SoLaMi Smile's live, Aroma reluctantly decided to target Shion and Dorothy next.
In this episode, Aroma is first seen hiding behind a pillar as she watches Dressing Pafé's Shion and Dorothy argue about the contest. While she decides to go after Dorothy, Mikan needs a little coaxing...which arrives in the form of a meat bun. Aroma is later seen arguing with Dorothy as she stubbornly refuses to join Aromageddon - and is visibly shocked when Aroma tells her that Shion has already joined. Skipping ahead, the pair is spotted by Laala at the end of Dressing Pafé's live, with Aroma seething in frustration. As SoLaMi Smile leaves Pripara for the day, relieved and happy for their rival team, they run into Aroma and Mikan, with both of them visibly younger, and wearing the Paprika elementary school uniform!!
Aroma is first seen waiting with Mikan at Laala's house to pick her up as she holds a tape recorder. the three walk together, Aroma says it's good that she didn't realize they were in the same grade, because the it wasn't time yet. She then declines Laala's attempt to exchange tickets, and tells Laala of her plan to form Aromageddon with SoLaMi Smile and Dressing Pafé members. Later, Aroma messes with a science experiment, making it mist over with ice, and claiming it's her own power. When Mirei yells at her at her and gives her a ticket, Aroma turns into curse. In gym class, Aroma defends Mikan from getting a ticket by turning it into a blessing. Afterwards, Mirei confronts Aroma about her behavior, causing Aroma to retaliate by reversing the rules back to her, telling her her character is ridiculous, and that she will (with Mikan) rise to Divine Idol, and then moves on to harass Dressing Pafé in PriPara. After performing and gaining their entrance in the competition, Aroma once again announces their names, and the fact that they're teaming up Dressing Pafé.
Aroma is first seen reading from her Grimoire in front of a small crowd by the school grounds with Mikan besides her. The two play off each other in a small skit, causing SoLaMi Smile to speculate about whether Aroma is manipulating Mikan. As Laala catches up with the pair as they walk home, Aroma asks if she's finally accepted their invitation to join their unit. At that moment, a runaway dog races by, with two little girls chasing it. As Mikan catches it, Aroma names it Cerberus, the three-headed dog that guards the gates of hell, and insists upon her statement after its disregarded. She also places a charm on the dog to make it like her, which seems to work. She then begins to corrupt the two little girls by telling the pair about demons. As she pulls out her Grimoire, a childish drawing of her and Mikan falls out, to which she becomes very flustered. After the dog runs away again, she suggests the group split up and look. She takes one little girl, while Laala and Mikan take the other little girl and pick a side of the river to search. While searching, Mikan and Laala chat together, and Laala finds out that Aroma used to be very shy and quiet. According to her, she read a script one day that matched the demon's character birthday to her actual birthday, and was henceforth intrigued by demons, even writing her Grimoire. The two start playing at being Angel and Devil, which is how their idol personas come to be. Flashing back to the present, Aroma tries to get the little girl to yell louder by casting a charm on her. It works, only to have the dog turn around suddenly and run off again. As the dog is caught by Mikan in a pet store, she accidentally knocks over some boxes, causing three snakes to slither out. Aroma arrives with the the other girl to find her friend cornered by the serpents.The little girl casts a charm on Mikan for courage, causing Aroma to rush in, snatch up all three snakes, and throw them back into their box. After Aromageddon performs, the two swap tickets.
