You want 18+ for violence? Look up Inuyashiki. Doesn’t get mentioned enough. NOT to be confused with Inuyasha!
If you want risqué content… anime is not great for this due to censorship. If you wanna go hard, look up Redo of Healer. If you want something a bit more meaningful, look up Elfen Lied and TRY not to think of the context it unwittingly gives to SPYxFAMILY (specifically what it says about pink haired girls with horns and superpowers… more specifically the implication that Anya may be a diclonius).
