well Aoko, she's kinda the reason the multiverse is going to be destroyed, short version is super guilt for previous events. Zelretch treats everything like a TV show to avoid attachment and Gilgamesh and Kirei, well the former respects Satoshi's conviction and the latter is pissed off that he lost their battle of wills.
the rest don't know the truth except Fab who isn't present at the end.
his existence as a hero was yes, not his existence period.
@YOLF
it was his fate to die yes. More importantly it was his choice to accept that fate for the people he loves. Ultimately their hope for his return can only be fulfilled if the readers think he deserves their love and allow the wish to come to pass. I've been serious about this from the start. He comes back only if you guys thing he deserves to come back.
Love, hope, sacrifice, kindness charity and generosity are the themes of the work. Humanity is awesome sir.
