TL note: 聖歌隊 (seikatai) is the word for “choir”, but if one takes each character individually, it would mean something like “Sacred Song Corps”. It is possible that the author wants to imply that meaning. “Elvennotes” itself is written in many different ways through the cards, but not with this particular word.

TL note: The particular Power Patron mentioned here is Artmage Power Patron by its title, “獄神獣” (imprisoned divine beast)

Bottom left: “The power is going berserk and overflowing”
