In order for lko to take the next step in becoming a VTuber sensation, she must cultivate her brand, and that means she needs a theme song! When an initial attempt falls flat, there’s only one person she can turn to: Rikka. Meanwhile, at school, preparations are in full swing for the upcoming cultural festival, and all the girls (and Arisu) have a lot on their plates. Not only are each of their homeroom classes doing their own themed booth, but the broadcasting club has to put on a display, too. Everyone is so busy, will they be able to put on a good show? But perhaps the biggest hurdle lies with Nene, who’s been keeping a secret…one that could mean the end of the broadcasting club as they know it!
