I'm on volume 22 on the LN, and I can't search for my answers in the internet.
If geese was an apostle of hitogami all along (since the teleportation incident), how come during the asura/ariel arc, hitogami still had 3 apostles: Darius, luke, reida. Won't that make 4 apostles?
I remember reading that a few volumes before that they kept only finding 2 apostles, but never the 3rd/last, so I'm just confused on this part of the plot.
Or did hitogami discard geese for a while, and took him back later on in the story?
