Lieben is the daughter of Bloom Metzelei and one of her many "children". She possesses restorative powers that allow her to heal everything she wishes. Due to this power, there were many kidnapping attempts on her, so Bloom hid her in a forest on Earth for her own safety and told her to remain there. She is a kind soul who is highly attuned with nature, taking care of everything in her forest while waiting for Bloom to return. She detests unnecessary violence, but will fight to defend.
