Toaru Kagaku no Railgun T
Rainbow is a good anime
Toaru Kagaku no Railgun T
Tokyo Ghoul
Cowboy Bebop
Afro Samurai
Fire Force
Really depends on what you like, I have some darker shows I could recommend
You should watch Tokyo Ghoul if you haven't yet.
Tower of God and jujutsu no kaisen are two good anime to watch
You can't go wrong with Berserk, and the guy who made it died so you won't get nasty spinoffs messing up the works
Rainbow is a pretty interesting one. I liked it
