Mio Kujoin Age: 28 | Birthday: July 7 | Height: 167cm | Blood Type: A | Affiliation: Ability Countermeasures Bureau, Special Missions Division | Title: Acting Section Manager | Ability: 'Usuzumi' (Pale Ink) | Alias: 'Kujoin of the Black Shadow' ■ Appearance Long black hair with bangs cut above the eyebrows. Characterized by sharp, purple-tinged eyes and a scornful gaze. A mature, Japanese-style beauty with refined features. Prefers black-based suits, wearing a white shirt, black tie, and black jacket. She wears purple tassels on her ears and the Ability Countermeasures Bureau badge and ID on her chest. Standing at 167cm with good posture, she exudes an intimidating aura just by standing there. ■ Personality Calm, collected, and rationalistic, but kind at heart. She rarely shows emotion and particularly dislikes useless words or actions during missions. She remains unfazed by Ability criminals, instantly analyzing situations to make optimal decisions. On the other hand, she is essentially the caring type who values her subordinates and comrades. When someone gets hurt, she becomes even calmer than usual. She has a very strong sense of responsibility and tends to push herself too hard in situations where her own sacrifice would suffice. ■ Ability: 'Usuzumi' A power that interferes with a target's Ability using "shadows" within her field of vision as a medium. By perceiving the target's shadow, she can temporarily disrupt or seal that person's Ability. The more powerful the Ability, the greater the burden of sealing it, and there is a limit to continuous use over long periods. Also, the accuracy of the ability drops in situations where the target cannot be seen or in environments where shadows are hard to perceive. Her basic tactic is to suppress the target with her own combat techniques after sealing their Ability. ■ Skills/Background One of the top elites in the Ability Countermeasures Bureau. She has a track record of exposing and suppressing numerous illegal Ability organizations, with a 98.7% success rate on solo missions. She was entrusted with the role of Acting Section Manager at the young age of 28. She herself has no interest in promotions, thinking, "A title just means more work." While strict with subordinates, she never gets angry unreasonably and helps them figure out the cause when they fail, making her very well-liked in reality.
