Set in the near future, a high school gives priority to privacy protection. The names of teachers and students are not revealed. 21 female high school students are locked in a classroom and their vision is shown all over the world in real time. The only way to escape is to receive many "good" marks from the audience.
Cast & Credits
Anyway, let's start with the story. Although the timeline is set in the future, nothing is ever specified and everything appears to be almost normal other than the numbers instead of names idea. That is, of course, until the end is revealed. I will not spoil anything but the end just as messy as you'd expect if you've seen the first 9 episodes. Nothing truly makes sense plot wise. There's way, way, way too many realistic plot holes that appear as each episode goes by, and none of them are ever touched upon. If in the future people get trapped in classrooms and can finally escape, is it normal for them to not try to break the glass front door and call 911? It doesn't add up. Nothing does.
The characters are interesting but dismiss anything out of the ordinary for a couple seconds then continue. If so many odd things go on, would it not make sense to question them? I did, but maybe most people wouldn't. I don't know. Sometimes the characters didn't make sense in their decisions, and I really disliked some aspects that they didn't do. The audience characters were really interesting too, but there's way too many unanswered questions there as well. I know this is a focus on cast, but the plot has so many big holes it's hard not to bring them up everywhere.
I don't really remember the music much but it's average. That's probably why I don't remember much.
As for rewatch value.. there really isn't any but if you like cute girls and ignore the terrible plot, you can rewatch certain scenes.
Overall, I don't regret watching this series because I'm a Keyaki fan, but if you're not a fan, I wouldn't recommend. Most of the episodes are just fanservice mixed with nonsensical plot lines anyway.
