It's just annoying how Manji has poor sword play. He gets cut faster than any anatagonist he faced unless it's just a filler character.
He's known to have killed a hundred even before he was immortal and he could've died already the way he fights now. It seems like his victims would die because they're unaware that he'd come back alive. No sword fighting technique at all for a swordsman
At least we could have seen better fighting from him.... and what's up with all those blades??? Where the hell did he even put it inside his kimono?
Well, that's my two cents about the anime. Other than that, the anime is good
