I've got a question about blooming - are dupes of the knight somehow needed in the blooming process?
I remember reading that someone was keeping dupes of higher rarity knights for some reason connected to either blooming or the second affection level (or something else that's not in the Nutaku version right now).
I've read the DMM english wiki on blooming and it only mentioned Birds, Petals and Elixirs as required components. Is anything else needed?
