Die Aqours haben den LoveLive-Vorentscheid erfolgreich überstanden. Jetzt haben sie ein neues Problem: ihre Teamkasse ist ratzeputze leer. Das heißt, Ärmel hochkrempeln und Jobben gehen!
After passing the Love Live qualifiers, the girls realize that they are short on cash for their activities and start looking for ways to raise some money. Meanwhile, Dia becomes uneasy with how Kanan and Mari are close with the others and looks for ways to get more personal with them to no avail, even after some counseling with her third year friends. During a part-time job at the local aquarium, some children start making a ruckus until Dia steps in to calm them down. Once Kanan and Mari reveal to the others Dia's intentions, they approach her and reveal that they admire her mature, responsible self, and that she does not need to change for their sake.
ラブライブ！予備予選を1位通過して波に乗るAqours。──と、思いきや、2つのステージを披露するために活動費を奮発しすぎて、残金がたったの5円に。みんなでフリーマーケットに出店するも、ダイヤのあまりの気迫にお客さんが去ってしまったりと前途多難。そんな中、後輩からちゃん付けで呼ばれて慕われる果南と鞠莉を見て、ダイヤは自分だけ距離をあけられていると寂しく感じてしまう。水族館のアルバイトを通じて、後輩たちと仲良くなろうと頑張るダイヤだが──。
3학년인 카난과 마리에게는 언니라고 부르지만 그들과 같은 학년인 자신에게는 선배라 부른다는 사실을 깨달은 다이아. 후배들과의 거리를 좁혀 더 친해지기 위해 노력하지만 뜻대로 되질 않는데.
Dia percebe que Kanan e Mari parecem estar mais próximas das meninas da Aqours e ela não, e começa a desejar que a chamem de "Dia-chan".
Dia es una chica muy seria, a veces en exceso. Eso hace que las demás chicas mantengan una cierta distancia y seriedad hacia ella, pese a que ella no quiere eso.
