That was a very nice silent comic.. Although, I do not know if the panels with the two side's companions slowly disappearing is actually depicting time lapse and death of age of those people.
Since on the 2nd part, Udonge disappears, but Keine doesn't seem to age at all. Maybe they just got bored of all the fighting and thought it was a waste of time.
Sorry if my comment made you feel worse about this comic... It's a really heartwarming story still.
Mokou's facial expression still gives me the impression of a old Japanese political comic on the newspapers though..;
Its a very sad comic and I have more respect for Kaguya from it. But knowing Keine I doubt she would just leave Mokou to fight alone and the ending proves it. As for the political comic thing I agree with you on that. It is a somber comic depressing but I don't know I dont feel as bad maybe because of the ending.
