Personality
Elaine is shown to be a kind, caring and forgiving girl, who cares deeply for Ban and is willing to forgive King for abandoning her and the kingdom, but is slightly disappointed and unhappy that he did so. Due to several humans repeatedly trying to steal the water of the Fountain of Youth with malicious feelings, Elaine came to distrust humans, but soon came to trust Ban when she read his heart, and even started to have feelings for him. Like her brother, King, Elaine becomes bashful and embarrassed easily when it involves Ban in embarrassing situation.
Due to Ban's encouragement in trying out ale, Elaine became angry or high drunk as seen in the OVA.
History
Seven hundred years before the beginning of the series, Elaine's brother, the Fairy King Harlequin abandoned the kingdom[1] to go out and save his best friend, Helbram and other Fairies, forcing Elaine to become the Fountain of Youth's Guardian Saint, live hundreds of years of solitude, and preventing her from leaving the Fairy King's Forest.[2] As time passed, Elaine came to distrust humans as an aging king who dreamt of ruling forever sent an army to invade her country; a merchant who dreamt of endless riches and attempted to steal the Fountain of Youth from her; and finally a savage tribe attempted to burn the Fairy King's Forest down with her but all of those attempts were thwarted by herself.
