Aigo Kinjō works in the Planning and Sales department at Minette. Originally from Okinawa and 24 years old, he is technically a junior colleague to Kentarō Momose, though they interact as equals. Kinjō, like Momose, left his prior job due to severe power harassment under a toxic boss. Witnessing the positive dynamic between Momose and their new boss, Shirosaki, in public motivated him to join Minette. He has an average height, notably shorter than Momose, with gray hair and gray eyes. Kinjō typically wears a white suit, a light blue or white shirt, a black tie, and black shoes, styling his hair with a middle part. Kinjō displays a calm, polite, and empathetic personality despite past workplace trauma. He is outgoing, playful, and socially adept, frequently visiting local bars to meet people and actively sharing interesting content on social media. A repressed otaku, he occasionally reveals this side, like showing Shirosaki his adored male video game idol "waifu," which confused his boss. Kinjō has been flirtatious since childhood, using pickup lines indiscriminately on men, women, and even his mother. He acknowledges a tendency to become overprotective and intense in relationships, leading to short-lived romances; one ex-partner (referred to with they/them pronouns) dumped him after a week due to his "overboard" attentiveness, while an ex-girlfriend ended their relationship after three days because he texted excessively. He is openly bisexual. When asked about his "type" by a coworker, he stated looks are irrelevant, valuing inner cuteness and being open to any gender or age. Later, while scrolling through his Enstagram gallery with Momose, he casually referenced two ex-girlfriends and one ex-boyfriend, the latter causing Momose visible shock. Kinjō uses flirty language toward male colleagues, including Shirosaki, such as inviting him to a festival date with a pickup line. Kinjō demonstrates emotional supportiveness, comforting his insecure superior, Aoyama, during low moments. His past trauma occasionally resurfaces, like distress caused by a social media interaction with his abusive former boss, though colleagues rallied around him. He contemplates moving out due to noisy neighbors but shows no overt trauma-related anxiety compared to Momose. His name combines "love/affection" (愛) and "enlightenment" (悟) for "Aigo," and "gold/metal" (金) and "castle" (城) for "Kinjō."
