I was much more impressed by this anime than I expected it to be it was something I picked up on Crunchyroll and didnt expect much out of. Granted I had been spoilered for the basic premise so knew what I was getting into on that front but regardless thought it would be handled sloppily and immaturely like some others I could mention. Im glad I was wrong. Its really hard to say without spoiling but Im going to try on the off chance that youve read this without actually reading the synopsis on here first. The characters were developed well some more than others. The flashbacks in this case were very well done they were brought in at exactly at the right time and even though the characters didnt exactly grow through the backstory it certainly gave them far more depth. I will say I really didnt like Yuki the MC but I could understand her. It really didnt feel like she was a high school student though. The other 3 main characters gained more depth simply as more of the surroundings were explored and you could get a better glimpse of what they were dealing with on a daily basis. It made me appreciate and empathize with them more and I felt it was actually handled quite realistically not that Ive ever experienced anything remotely like what happened in this anime but it was consistent with other decent literature Ive read on the subject. Sound was good and art was good. No complaints on either of those two. Normally Im not one for the cutsey art style but I can understand why it was needed here. All in all a pretty good attempt at its genre. Why didnt I rate it higher? Because I didnt think it was THAT good. It didnt feel like a masterpiece or anything. The series was enjoyable but it did get repetitive about halfway through. There wasnt much to the show apart from the premise though in its defence I dont think there was meant to be. And whilst I liked the characters and thought their stories were done well the show didnt make me that emotionally invested in them. Yes I could appreciate them and empathize with them to an extent but nothing similar to what I felt in Shinsekai Yori or Zankyou no Terror. Still let me reiterate it did impress me for what it was and Id recommend you give it a go. XD
