Desirée "Dessie" DeLite, a motorcycle enthusiast and unapologetic shopaholic, balances her high-maintenance lifestyle with a marriage shaped by secrets and heroism. Her bond with Ron DeLite ignited when he rescued her from a workplace robbery as a KB Security guard, their whirlwind romance culminating in marriage. Struggling to fund her indulgences, Ron turned to stealing corporate secrets, losing his job and adopting the "Mask☆DeMasque" persona to sustain their life covertly. Unaware of Ron’s double life, Dessie adorned their home with thief memorabilia, mistaking it for fandom rather than evidence, her lingering trauma from the robbery fueling a staunch disdain for criminals that silenced Ron’s confessions. When Ron admitted his crimes, Dessie dismissed his claims as delusions, clinging to the belief he still worked legitimately at KB Security. During his trial for stealing the Sacred Urn, she uncovered the artifact in Luke Atmey’s office, presenting it as evidence. Initially deemed forged, Phoenix Wright’s fingerprints proved its authenticity, exonerating Ron and implicating Atmey. Later accused of murdering Kane Bullard, Ron faced trial again, while Dessie’s alibi—a speeding ticket—secured her innocence. Post-acquittal, their visit to Zodiac Hall to admire Paul Halique’s sculptures hinted at Ron’s unresolved intrigue with heists. Thrill-seeking defines Dessie: she races motorcycles recklessly, needles Phoenix Wright with the nickname "Nicky Boy," and dances between adoration for Ron’s grand gestures and denial of his criminality. Their relationship thrives on shared fascination with antiquities and his desperate attempts to satisfy her spending, masking her inner conflict between love and ethics. Paradoxically, the couple later founded an organization rehabilitating thieves through reformed heist plans, blending advocacy for honesty with clandestine scheming. Linguistic nuances underscore her character: "Desirée" (French for "desired") mirrors Ron’s relentless devotion, while "DeLite" ("delight") reflects his pursuit of her happiness. Her Japanese surname "Amasugi" alludes to naivety, echoing her willful ignorance, and the French localization "Désirée Duplaisir" intertwines "pleasure" with her insatiable desires.
