As soon as Erika learns the Athletic Festival after-party will include a solo dance by Akebi, she decides she wants to be the one accompanying her on the piano. Usagihara gives her the encouragement (and the Miki-chan CD) she needs to make it happen, while keeping it a pleasant surprise for Akebi when the time comes.
As for Akebi, she and her volleyball team learn, through playing against an actual volleyball player like Washio Hitomi, that they aren’t that god at volleyball. They don’t lack heart, but they need practice, and more critically a place to practice. Akebi has a tearful call with Mako-sensei, who is so happy Akebi has made friends and gives her permission to use her old school gym.
At first it looks like it’s going to be just Akebi, Usagihara, Shijou and Minakami (plus Kao, who wants to know what it’s like to not be at that school all alone), but Washio and Nawashiro, initially thought to have been indisposed that day, show up to help the novices practice. I love Kao’s reaction to seeing the statuesque Washio, as well as Washio’s response: lifting Kao as high as only she can.
I never watched Haikyuu!! but speaking as someone who has watched a bit of anime, I’m confident in saying the volleyball action animation is excellent. From the power and grace of the experienced Washio to the fumbling and incoordination of the newbies, it captures all of the beauty inherent the sport. Perhaps more importantly, it’s another opportunity for Akebi to revel in all of the friendships she’s made, working together in hopes of winning at the festival.
When Akebi shows her to the restroom, Usagihara notes just how old the school is, and learns that their little practice session is not only the most activity that gym has seen in years, but also might be the last time such a session can take place. Once Kao graduates, the school will close. So Akebi is happy she could bring friends there.
Akebi returns to the gym just as Mako-sensei decided to peek in on their practice, and is surprised to find that practically her whole class turned out to practice with her, preparations Usagihara made in case Washio and Nawashiro couldn’t make it. Mako-sensei and Akebi cant help but get emotional, while Kao leads her big sis by the hand to continue practice with everyone. Akebi shows her gratitude by giving Usagihara a big and lasting hug.
As for Erika, she’s in her own little world in her dorm room, practicing the Miki-chan piece while wearing earbuds and envisioning Akebi dancing around her in a placid ocean. Akebi truly transforms into a magical girl, gracefully darting around as Erika accompanies her. It’s another big flex from the animation staff, as the scene is simply bursting with love, tranquility, energy, and beauty.
