I'm not convinced Aramaki is a swordsman.
Maybe it's from his lover, or it was inherited as already a black blade.
I need to see on panel that he is a sword main and not DF main.
Until then, Aramaki is treeman not swordsman.
It would be damn embarrassing to have a logia + black blade and still not become the WSS.
Maybe the logia power is new and he just got it from becoming an Admiral.
Well then, it's time to challenge the criminal Mihawk, Aramaki!
