Looking for recommendation - eviltoast

Im looking for anime with adult or at least adult like cast.

So far i watched:

  • Monster (which is my favourite)
  • RIN ~Daughters of Mnemosyne~ (also my top pick)
  • Golden boy
  • Claymore
  • Cowboy Bebop
  • Ninja Scroll
  • Ergo Proxy
  • Mushishi
  • Death Parade
  • After The Rain
  • Gantz
  • Vinland Saga
  • Death Note

I would appreciate any good recommendations in that style. Thanks!
