You’re getting ZERO points with this, my point however still stands tall
Issho is blind, he carry’s a sword to mainly navigate his attacks n such, we haven’t seen him display pure swordsmanship, he also uses that sword to sense his directions like a walking cane
but like I said already, he’s not a pure swordsman, he’s only just a swordsman hence why he’d rather summon in a meteor to crush you rather than sword duel to the bitter end.
