Amazing anime, just a whole amazing plot. At first, I would always see it on Netflix and just scroll past since it didn't seem worth it. I wanted to see what it was about though before I said negative things about it. 1. I fell IN LOVE with the intro. I absolutely just loved the intro. Till this day, I go back re-watch the intro. I re-watched the anime, A LOT. I know the plot by heart and to be honest, it was one of the animes where I actually felt something. The characters and the way they died always got me in my feelings. Especially Yuri, Ayato, and Yuzuru's. This anime, I 100% recommend. I do not regret watching it. (SPOILER) To be honest, I really wanted a season 2 where we get to see the reincarnated again, but they won't be making another one because the cours was so rushed. It was supposed to be around 26 episodes, but I got cut down to 13 episodes. Luckily for us, even though it was rushed, we got a proper ending.
Through all of that, I loved the anime and it will not waste your time!
