Seolla Schweitzer was raised under extreme discipline within "The School" and its successor institution, designated Bronze-27. Aguila Setme's supervision enforced strict obedience, shaping Seolla into a highly dutiful individual who meticulously followed orders. This rigid adherence to protocol frequently brought her into conflict with fellow student Arado Balanga, whose casual disregard for missions drew her reprimands. Despite these clashes, the two shared a profound bond, pledged to survive their harsh upbringing and eventually live peacefully alongside other Boosted Children and their older "sister" figure, Ouka Nagisa, away from conflict. Their relationship remained complex; Seolla openly criticized Arado's recklessness in their Armoured Modules, yet they were deeply important to each other.

A pivotal moment occurred when Latooni Subbota, a former companion from The School now serving the Earth Federation Army, shot down Arado. Following this incident, Aguila Setme subjected Seolla to brainwashing. This implanted false memories, convincing Seolla that Aguila had always been a caring mother figure deserving of her gratitude and obedience, and that Latooni was responsible for Arado's death, fueling her desire for revenge. This belief persisted even after Arado was confirmed alive and recovering aboard the Hagane.

In combat, Seolla pilots the Wild Falken Personal Trooper. Her experiences in The School and subsequent conditioning heavily influence her piloting style, often manifesting as intense focus and strict adherence to tactical directives during missions. She appears as part of the supporting cast in the anime "Super Robot Wars Original Generation: The Inspector," continuing her involvement in the depicted conflicts.
