yo that flashback scene... was it straight from the old manga or is it a newly drawn thing?? if it is a newly drawn thing then that's kinda awesome considering it has the old artstyle
he's faked his own death to live peacefully as a painter in the gaiden so it's sorta possible for him to make a comeback (i will personally shit myself so hard if he does btw)
i heard that this is Itagaki Keisuke's favorite manga which what got me interested in it and after seeing a couple of chapters of it i honestly can say that it's a pretty cool manga
