Hello! I would like suggestions for an anime to watch, I've watched quite a few.
Shows like One Punch Man rate highly for me, but I'm looking for Thrillers, and the sort of shows that give you the chills when a plot twist is revealed, like Steins;Gate and the first episodes of Attack on Titan, Sword Art Online and Re:Zero. I really, really like shows which these awesome twists, or even just unexpected events that the protagonist has to face.

I don't enjoy mind-game type shows like Death Note or Code Geass as much, and I really hate childish protagonists-- figuratively; I don't mind child protagonists so long as they aren't inhumanely stupid and/or they don't cry excessively (My Hero Academia). I'm also not looking for shows that just feature one thrilling bit or twist every once in a long while (School Live!), it's got to be centred around the thriller.

I'm pretty sure Madoka Magica also fits into this unexpected thriller category, but I don't think I'd be able to stand watching a magical girl show in between the the thriller/psychological bits. Any suggestions are welcome, thanks!
