Vividred Operation - 1x04 - 約束- Followmy.tv

Akane, Aoi and Wakaba's latest fight against the Alone are observed by Himawari Shinomiya, a girl who spends her days confined to her room and participates in classes through a camera. Following the battle, Wakaba starts training Akane and Aoi so they can safely dock in battle. As the girls attend gym class, Himawari spots Kenjirou through her robot's camera as he investigates who's been hacking access to files on the Alone, before it is smashed by a wayward baseball hit by Akane. The girls go to Himawari's apartment to apologise, where Himawari asks to inspect Kenjirou, which Akane passes off as a stuffed toy named Uso. Noticing Himawari has a thing for factories, the girls dress her up and take her to see one of them. Just then, the factory they are visiting is attacked by the Alone from the previous day, which had undergone an evolution. As the girls transform to defeat it, Himawari heads to the plant to shut it down, but soon gets caught up in a cave-in. Recalling how she was betrayed by her previous friend, which led to her to become a shut-in, Himawari is rescued by Akane, who kept her promise to come back for her. Touched by this, Himawari gains an ignition key, joining the girls in their fight. After the Rei powers up the alone again, Akane docks with Himawari to become Vivid Yellow and defeat the Alone. Following the battle, Himawari decides to start attending classes before asking Kenjirou for his autograph.
