Random thought but am I the only one who thinks it's cheap the way Kishi suddenly decides to kill off random characters at the end of the manga? I mean these deaths really don't have a great impact in the story & won't lead to future development for future arcs since the manga is on it's last legs. Seems rather pointless.
I sense the editors hands in that. This is the final act, so Kishi needs to ramp up the shock and awe as much as possible to enhance the eventual defeat of the final enemies.
