After graduating from Bormeo University, Allen joined Vector Industries' First R&D Division in T.C. 4764 and was placed on the KOS-MOS development project under then Chief Engineer Kevin Winnicot and Junior Chief Engineer Shion Uzuki. Although two years Shion's senior in age, in Vector he's one year her junior. After the incident where the KOS-MOS Archetype was prematurely activated by U-TIC, which resulted in Kevin's death, Shion was promoted to Chief Engineer and continued her mentor/fiancé’s work while Allen was then promoted to Shion's former position as Junior Chief Engineer.
