Bungo Stray Dogs 4

Long before the Armed Detective Agency was a thing, Yukichi Fukuzawa was just a retired military swordsman trying to make it as a freelance bodyguard — and honestly, not doing great at it. Then he meets Ranpo Edogawa, this loudmouth kid who claims he has a supernatural deduction ability, and they get pulled into a strange murder case that changes everything. That's where Season 4 picks up, rewinding the clock to show you how the agency actually came together. This is a 13-episode TV series from Studio Bones, and the animation during fight sequences is as sharp as you'd expect from them. But the real draw here is the character work. Fukuzawa's quiet intensity bouncing off Ranpo's bratty confidence gives the origin story actual weight, not just fan service backstory. The show weaves real literary figures into a supernatural crime thriller set in Yokohama, and the mystery elements have genuine teeth to them — you're piecing things together alongside the characters. The vibe sits somewhere between Psycho-Pass's morally gray investigations and the chaotic ensemble energy of Durarara or Kekkai Sensen, but with its own identity rooted in literary references and layered power dynamics. If you liked any of those and want something that balances slick action with detective work and organized crime drama, this season rewards you whether you're a longtime fan or just curious about the franchise.
