Looking for recommendation

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!
