Yukine is impressed with Mahiru’s ability to provide hard numbers for why JELEE deserves a spot at the New Year’s show alongside SunDolls, but stats aside, Yukine wants to know what Mahiru is doing this for. Mahiru’s answer is that when someone does something for her, she wants to reciprocate. Kano made her want to get back into art, so she’ll make Kano want to get back into singing.
And Kano does want to sing; she just feels lost without Yukine or Mahiru as people to sing for, believing she’s lost both. While that’s not really the case, the bottom line is she gets pre-show jitters, and is especially intimidated by the live audience in the park. This is where Kiui and Mei step up, steady her hands with theirs, and tell her she’s got this, because they’ve got this.
Even so, once the SunDolls leave the stage and Kano steps onto it, she’s so overwhelmed by the negative voices in her head that she can barely get a whisper out. That’s when Mero of all people, who spotted Kano earlier, tells her to look around her, where she sees that the park has well and truly become something of an aquarium. Mahiru also offers words of encouragement from her perch above the stage; their first interaction since Mahiru went to work for Yukine.
With both former enemy and friend united in their support and surrounded by the “Shibuya Aquarium” she and Mahiru dreamed of building, Kano can sing with her full voice, shining like, well, a jellyfish in the light. It’s an unqualified success, with Kiui spending most of JELEE’s revenue on a 3D JELEE girl model like the ones made for the SunDolls.
When her performance is over, Mahiru rushes to Kano, but the two end up on opposing escalators. Eventually they do embrace and apologize for hurting each other. As the credits for the show run, they’re joined by Kiui and Mei, and while Kano doesn’t see her mom right after the show, Yukine does end up acknowledging her in the credits, as Hayakawa Kano, her daughter. It’s a powerful cathartic moment that causes Kano to bawl her eyes out.
Kano and Kiui end up getting their shit together and graduating after all along with Mahiru and Mei. Kiui continues her fling with Koharu, both off and online; Mei the superfan gains a fan of her own who is far more like she was than she knew; and Yukine shows up to congratulate her daughter and note how much she’s grown. Kano and Mero even bury the hatchet and become friends, while before they were only co-workers.
The members of JELEE commemorate their graduation and the start of the next step in their lives by painting over Mahiru’s old jellyfish mural and painting a new one over it in a collaborative effort, cleverly and intimately documented with the girls’ cameraphone footage.
While before they were four jellyfish drifting in the night, unable to swim, now they’ve each chosen their own colors and thanks to one another’s support are able to shine on their own. It’s a happy, heartening, if tidy way to bring this colorful and beauitifully produced show to a close.
