Roe2 is Shiroe's alternate character avatar, a Half-Alv Summoner-Vampanella. Although she was originally on Mare Tranquillitatis, her body ends up being used by a Fool who is intent on finding out who was rightfully in possession of Theldesia's Empathiom, whereas the Genius are simply intent on harvesting it by killing Landers and Adventurers alike. As a result, Roe2 primarily opposes the Genius and aids her "big brother's" (Shiroe's) cause.
