It does give some back story to Froppy(Tsuyu), just like the manga but then it delved even further into a new story line that never appeared in the manga. Pros: Still good new/fresh story, new quirks. Cons: Tsuyu isn't the most interesting of characters' to get some background in. ~SPOILERS~ Only the very beginning of the episode about her parents and siblings are from the manga. Everything else is brand new a very cool quirk(zombie virus) that "acts exactly like in the movies," to quote Deku. Worth a minimum of one watch. How can i write a longer review when this episode is only 21 min long and how longmust it be.(5)
