Don't misunderstand me, i don't really like that story, and not gonna "shill" for it.
Story is full of plotholes much larger than that, and blatantly speaking plot presentation is boring as f.
So what i want to say, suiboku's action make much more sense than this entire manga.
"Murdering psychopath"... well, it's not exactly wrong, but keyword here is "in the past". He changed, the same way that our MC changed. After so many years in solitude with only swordpath and nothing else, made them lethargic and indifferent. He reached enlightement and can't even be called a human anymore. His emotion is paralized, his only goal is reaching new height of the sword. Why should he deny simple question?
I just wanted to say, that i kinda dropped that manga long time ago, because it's just plain boring, even though i rather enjoyed initial plot idea, such a shame. Well, i'm still here, but not to extent that i'm waiting for new chapter, right now i'm indifferent to this as much as suiboku
If anything, the only thing that i wanted to see is their reaction to his age... In which autor also wasn't able to meet my expectation. Everything was plain as the name of the manga suggest...
Just find it quite strange when people say that suiboku's action was "last straw". After all those horrible chapters before, suiboku's action can't even be considered strange and rather fitting to his character.
