I really love this anime. The characters and character designs are unique and memorable. But my personal favorite part of this show is how it displays mental health. Like most shows I've seen mental problems seem to just "go away" as the show progresses, but that's not how it works. In BSD, they have several characters that have mental problems, and guess what? That follows them through the whole series! Additionally, the story past season 1 is so compelling and very engaging! If you enjoy dark, mystery or adventure anime, then you should give Bungou Stray Dogs a watch!
(Plus you should check out the 1 star section. There are two people that clearly have a screw loose. It's hilarious.)
