She was the sister of Ries Argent and responsible for bringing Kevin Graham into the Aster House orphanage in the midwestern city of Emerose. Until her death in S.1198, Rufina stayed by the side of her best friend and the Dominion she supported, Ein Selnate.
Rufina was a patient and gentle person, who settled disputes through peace rather than force. Her unparalleled ability to choose the best decision out of a myriad of possibilities earned her the alias of "Thousand Arms". Rufina wielded both a templar sword and a bowgun, with a track record of never having lost a single battle. At one point on time she engaged in a battle with Loewe, who reckoned he had rarely been challenged at that level. Rufina herself described the outcome of the fight as a tie. Her prowess is also recognized by the fact that Ein Selnate never had to resort to her Stigma's power because she had Rufina by her side.
Five years prior to the start of the series, Rufina was seemingly killed in the line of duty during a raid by a jaeger corps on Aster House. In reality, she sacrificed herself in order to save Ries and ease Kevin, whose Stigma awoke during the raid and was unable to distinguish Rufina and Ries from the jaegers.
- Among the unused files in The 3rd is a flashback where Rufina confronts Georg Weissmann as he leaves the church.
- During the final chapter in Ao no Kiseki on the elevator to The Road of Farthest, the shot in which Rufina burns in the flames during the opening to The 3rd is among the memories flashing by in the background.
