peko was once complaining that she cant turn stones to bread for food without her powers. Lierre could do that for her & even bring someone back to heaven. yet she does not help pekora out at all.
Judging by the fact that there are so many traitors among angels, and by how Pino thinks about her, it seems Lierre really doesn't manage her subordinates well lmao. She even made fun of Pekora a few chapters ago.
