Aima would technically be considered one of the oldest competitors on the roster, if anyone truly knew what her age was. Since becoming a vampire long ago, Aima has no clue how long she has truly been around, at a point, she stopped caring to keep track. After succumbing to vampirism, Aima is forced to live a life in shadow. Direct sunlight is her primary weakness, as it causes her great damage. The helpful part of being a vampire however, is that normal attacks against her are quite ineffective, and the only way to truly deal with her is to expose her to sunlight. For hundreds of years it feels like to Aima, she has remained trapped inside her "home", a ruined building in the middle of nowhere that protects her from the sun. Early on into finding the building, Aima discovered the then dormant, but still somehow alive, Morana. The two quickly became friends, and before long, the two were visited by chance by a beautiful countess, Camilla, who looked like the last kind of person they would ever see in a place like that. She told them of some kind of Arena, and the life of action she longed for. Aima and Morana, both rather bored of their current situation, decided to join her, as the three slipped out into the night, heading to the Arena.
