In Episode 157, it is revealed that they were called by Takuto Tatsunagi, who had sealed away their memories so that they would assist him in protecting Cray and Earth. However, if Takuto were to disappear, their current memories would vanish. In Season 1, Kourin was the only one that actively participated in cardfights; she used a Royal Paladin deck centered around Fang of Light, Garmore. In Season 2, all three of them used Angel Feather decks.
