Tokyo Ghoul, maybe Parasyte. Guilty Crown is overrated but still fits the description. There’s also ones I haven’t watched like Code Geass. IMO, Psycho Pass is phenomenal. Darker Than Black also fits your description.
Yeah, it is. I’m just going off of the anime, not the manga from AoT or the light novel from SAO, so I might be missing HUGE aspects to their swordsmanship, but I do know that they both have secret “techniques”:
Kirito - Dual Wielding
Levi - Backhanded Strikes
It’s an amazing show. He starts to change and the last episodes are where it gets hella interesting. Also, I think you’ll like the ending
And Kirito is actually very good with the sword, but Yato’s knowledge and Levi’s maneuverability I think outclasses him
Personally I picked Levi because he can also use Vertical Maneuvering Equipment at the same time, but picking Yato is understandable
Rakudai Kishi no Cavalry...
Terror in Resonance... ...
Forgot their names but the two protagonists from Scum’s Wish
Tokyo Ghoul’s first season is alright but it’s Second is where it gets interesting. The third uncovers lots of mystery but the action is kinda poop.
Either way you can’t just NOT watch Tokyo Ghoul. It’s released impacted anime as a whole and I think that despite it not being the best that you should at least experience it
Attack on Titan’s very first opening. Jesus man, if you can’t even tell which of the OPs in Attack on Titan is better, you’re a lost cause.
I gave you the anime, now don’t be lazy and explore the OPs to see which one YOU PERSONALLY like best. The fan favorite is the first one, but that might not be yours. Don’t be a weirdo about it.
