Naaden operates an armor shop dedicated to crafting and selling revealing, high-performance armor exclusively for female adventurers. He possesses an exceptional eye for designing sexy armor, prioritizing aesthetics aligned with his vision above all else. This singular focus, however, leads to perpetually low profit margins, pushing his business toward persistent financial struggles and near-bankruptcy.

His foundational philosophy stems from youth, where mentor Rose Lohe instilled the core tenet of prioritizing sexiness in armor design. This training profoundly shaped his eccentric personality and professional obsession. He runs the shop alongside his daughter, Ririetta, who serves as the primary model showcasing the armor's functionality and appeal.

Naaden maintains professional connections with several recurring figures. The formidable swordswoman Frealica is a frequent customer, purchasing his armor despite its impractical appearance. Elf soldier Selas, stationed at a customs checkpoint, considers Naaden's behavior foolish yet maintains a friendship. He also interacts with the flat-chested sorceress Miina, who shares his appreciation for sexy designs. Additionally, he has a connection to the demon lord Near (Mao), who resembles a young girl and seeks to reclaim something Naaden stole from her.

Characterized by a serious demeanor sharply contrasted by his eccentric dedication to his craft – including noted perverse interests related to his designs – Naaden is typically depicted wearing an eye patch. His actions, particularly the theft from demon lord Near, occasionally instigate minor external conflicts that drive plot points involving the shop.
