Step One of the Magia Record finale: dig poor Tamaki Iroha out of the yawning chasm of despair into which she was cast by losing both Ui and Kuroe. First, Iroha shoots a Kyuubey or three in the face, not wanting to hear his platitudes about extending the universe. Harder to silence is her own doppel, who says she couldn’t save Ui or Kuroe because she didn’t ever truly know or understand them.
Iroha is no doubt in a bad way, but thanks to the timely arrival of Yachiyo and the rest of Mikazuki Villa, she’s able to share her pain and failures with them, just as they shared joy and happiness in brighter days. They connect with both hope and despair, sharing everything about each other. This maximum understanding means Iroha is able to conjure a giant crossbow airship that conveys the quintet to Embryo Eye.
Mikazuki and a huge army of magical girls manages to restrain Embryo Eye, while Iroha is able to fly through any and all obstacles to end up with her two remaining little sisters in her arms. Nemu and Touka insist she fall back, stay safe and let them keep her alive for a long, long time. But Iroha assures them more time won’t make her happy if it means they must sully their hands, or disappear. She wants to share as much time as they have left together.
While she’s finally able to get Nemu and Touka to stand down, the victory lasts only a few moments when we’re reminded that the wild card Alina Gray is still on the board, and crazier than ever. Of all the hundreds of magical girls deployed in this battle, it only takes one to muck everything up, and that’s Alina, who above all must be entertained and engrossed by art and excitement, even if it means sacrificing herself to merge her doppel with both Embryo and Walpurgisnacht.
Alina’s destructive actions threaten everyone, magical girl or not, and Iroha can’t hold Nemu and Touka back from doing what they can to stop her. In this case, that is summoning their own doppels, going into overdrive, then catching up with the Alina-Embryo Eye and destroying it before it can merge with Walpurgisnacht—sacrificing themselves in the process.
The resulting explosion turns everything white, and Yachiyo wakes up on a train in space, wondering if she’s dead. She’s soon joined by former villa sisters Mel and Kanae, and then by Momoko and Mifuyu. They tell Yachiyo they’re not ghosts, but fragments of their magic that live on within her. Thus is Yachiyo’s magical ability finally confirmed not as the power to survive by sacrificing friends, but the power to carry on their hopes.
After meeting with Ui and saying goodbye one last time (though Ui also says a part of her will remain with Iroha, specifically every time she experiences happiness), Iroha ends up in one last discussion with her doppel. But since she no longer fears her doppel, and has come to understand her, Iroha is able to remain in control, and even draw upon her doppel’s power, combined with Ui’s collective power, to connect each and every magical girl on the battlefield with glowing pink threads.
They’re not threads that collect despair, but seek understanding and sisterhood. One big happy magical girl family, all of whom know each other, and all of whom have a part of themselves in their others. She and Yachiyo connect and conjure a mammoth half-spear, half-crossbow bolt. Declaring that no matter how sad or regretful she gets, she’s going to keep living, Iroha fires the bolt, finishing the Alina-Eye off and dispursing Walpurgisnacht.
The clous part, the blue sky and gleaming sun bathes Iroha and Yachiyo in its warm light. The rest of Mikazuki Villa joins them, and they revel in their hard-fought victory. After the credits we see new occupants arriving at Mikazuki Villa in some undetermined but not necessarily distant future, with framed pictures of former tenants, including Yachiyo and her original group, as well as Iroha and her little sisters.
But they’re just photos of girls. As the girls in those photos narrate that nobody knows nor will know the struggles they faced, the sacrifices they made, the tears they shed and the blood they spilled. They won’t know they failed, were deceived, were stolen from, or that they fought each other, made up with each other, comforted each other.
The damage caused to the city is explained by a combination of earthquakes, typhoons, and terrorist attacks. What actually happened will never be recorded, and to the rest of humanity, magical girls and their record never existed.
It’s a expectedly sobering and haunting way to close the curtain on this bizarre world. But it doesn’t matter to Iroha if she was remembered, only that she got to be a magical girl, save people, and live and share in the lives of those she loved.
