Corpse party:tortured souls is the perfect anime for you if you like gore and you don't have so much time to watch an anime (it has only 4 episodes -and it's enough-)
Story (8/10):
A simple but interesting plot that will make you want to know what's going to happen
Sound (8/10):
In terms of sound, this anime has pretty good music (both op and ed and ost)
Character (7/10):
Maybe you'll forget some of the characters a few days later when you finish the anime, but they all have their personalities and they are all special for some reason.
Enjoyment (7/10):
If you don't like gore so much, please don't try to watch this. In fact, I don't love gore or something but I can stand it, that's the reason why I can rate this point with 7/10. Without this, the whole anime was pretty enjoyable if you like the genre.
Overall (8/10):
Corpse party:tortured souls was better than I expected and it kept me interested the whole 4 episodes.
