While playing softball, Akane’s home run that destroys the camera of the secluded hacker Shinomiya Himawari, whom Kenjirou just happened to ID as the the culprit in the theft of confidential Alone data. Akane, Aoi and Wakaba pay her a visit to apologize, and they end up visiting the site of the Streamer plant, which distributes energy to the world from the Manifester engine. When an Alone attacks the site, the three fly off to fight it, leaving Himawari to shut the plant down. Afterwards, Kuroki Rei powers up the Alone, and Himawari gains and quickly masters the Vivid System, docking with Akane to become Vividyellow and defeat the Alone.
And then there were four. We had a red, blue, and green techno shoujo (our own term for what they are, since it’s science and tech, not magic, that they use), so for completion’s sake, we needed a yellow. She turns out to be the egghead of the bunch, being a total Isshiki Kenjirou groupie and hardcore Manifester engine nerd. He brief backstory illustrates how a former friend she trusted betrayed her and turned her into a pariah, and so she’s been skittish about trusting or even interacting with people ever since. Himawari refutes Akane’s claim she loves the Manifester engine, not knowing Akane is its inventor’s granddaughter.
When Akane leaves her behind to shut down the plant while she fights the Alone, Himawari is convinced she won’t come back, even though she promised, because people have promised her things before and let her down. But Akane doesn’t let her down, and as a result of their newly-formed friendship, Himawari becomes the yellow one. Interestingly, the episode points out how quickly she learns the ropes of the Vivid system, though Saegusa learned it just as quickly last week. Her weapon, which reflects the Alone’s weapons back on itself, are suitably badass, and stuff get blow’d up good, as it should in such a series.
