Most people shouldn't forget what happened but, if you have amnesia or something, it might be worth watching. As it is a recap, it recaps the significant portions of the story from episode 1-7, however, it often takes too long in certain scenes and glosses over other ones that are equally important. It does a decent job of summarizing what is going on, but a few important scenes or explanations are missing so you HAVE TO go watch the actual anime.
Thanks for reading!
PS. Shuka is poor.
