Mahiru and Yukine discuss a JELEE and Sundolls collaboration. Mahiru explains JELEE is trending online and that their performance would attract huge crowds. Yukine points out such publicity stunts can backfire and affect Sundolls' credibility. Yukine asks Mahiru what she really wants to accomplish with the collaboration. Kiui receives Yukine's proposal to collaborate for the event. Kano agrees to the proposal. The day of the event arrives and everyone prepares for their performance. Kano is concerned about the performance as she still does not have a reason to sing. Mei and Kiui reassure her that she will do well. The event starts, and Kano freezes, confusing the viewers. Mero tells Kano to look ahead at the art Mahiru illustrated. Seeing her goal of creating an aquarium in Shibuya come to life, Kano starts singing. The performance is a resounding success, realizing Kano's vision for JELEE. After the performance, Mahiru and Kano reunite and embrace. The two spend some time talking about their experiences before the event. Kano explains that she finally found a reason to sing. Kano wants to help people move forward and find joy in their lives. The event credits play, and Kano is moved that her mother used her real name instead of her stage name. Some time passes, and Mahiru takes an exam to enroll in art school. Mahiru, Mei, and Kano graduate high school while Kiui continues streaming. The members of JELEE meet up in front of Mahiru's jellyfish mural. They decide to repaint the mural. While painting, they agree to continue their music group and vow to stay together. (Source: Wikipedia)
