Lamdimia Do Aximemor, a demon who immigrated to the Human World after the Demon Empire's collapse, works at the Lawson convenience store next to the Leon Magic Shop. She possesses purple eyes, long dark hair typically in pigtails, stands 143 cm tall, weighs 37 kg, and consistently wears her workplace uniform on duty.

Exhibiting a proud demeanor, Lamdimia insists on being addressed by her full name, correcting nicknames like "Lam" or "Lam-chan." This stems from her pride in her demonic heritage and desire for personal accountability. Though adapting to human society presented initial challenges, she eventually adjusted. Professionally, she demonstrates considerable sales aptitude, employing aggressive marketing tactics without ethical reservations to drive purchases.

Her primary relationship is with coworker and manager Elsa Crucial. Lamdimia frequently embarrasses Elsa by openly discussing Elsa's romantic interest in Raul Chaser, a former hero candidate at Leon Magic Shop. She supports Elsa's feelings, expresses pride when Elsa confesses to Raul, and becomes angered by Raul's perceived obliviousness. Lamdimia readily participates in promotional events, including wearing revealing attire during Leon's sales campaigns, and recruits other women for similar activities despite human modesty norms.

Originating from the Demon World, her full name carried significant recognition there. This established reputation contributes to her insistence on its complete usage in the Human World.
