Anri Teieri joined the Japan Football Union as a new recruit after the national team's 2018 FIFA World Cup elimination, an event that profoundly shaped her commitment to transforming Japanese soccer. She conceived and formally proposed the Blue Lock project, a radical training initiative aimed at forging a world-class striker to lead Japan to World Cup glory. Her vision directly contested the Union's conventional team-oriented play philosophy, which she argued hindered international success. Despite facing skepticism and dismissive attitudes from senior executives—who often fixated on her appearance or dismissed her as unrealistic—she persistently advocated for Blue Lock's approval, driven by deep passion for football and an unwavering belief in cultivating individual egoistic brilliance in strikers. Physically, Anri sports delicate features, neck-length brown hair typically styled with two small braids tied back and square bangs framing her left cheek, complemented by deep brown eyes. Her standard professional attire resembles a secretary's outfit, though official artwork occasionally shows varied formal wear. She stands 157 cm tall with recorded measurements of bust 88 cm, waist 57 cm, and hips 84 cm. Her daily routine at the Blue Lock facility is rigorous: waking at 5:30 AM for emails and yoga, overseeing player health data analysis, preparing reports for the Union, attending meetings with Ego Jinpachi, and ensuring project efficiency, typically concluding work by 8:30 PM. Anri balances calm professionalism with fierce resolve. Generally polite, she speaks candidly about her ambitions for Japan's World Cup success, remaining unaffected by the Union leadership's business-oriented ideologies. She exhibits intense focus, sometimes losing awareness of her surroundings when absorbed in tasks, and describes herself as unafraid of challenges. Her preferences include watching soccer matches, exploring spicy cuisine (favoring extra-spicy mapo tofu with rice), snacking on Country Ma’am cookies, and singing "CAT’S EYE" at karaoke. She dislikes sea cucumber and being disturbed while sleeping. Her hobbies reflect her football dedication, often involving reviews of Premier League matches. She recruited Jinpachi Ego to lead Blue Lock, trusting his unconventional coaching philosophy centered on egoism and individual brilliance despite his initial condescension. Acting as his primary supporter and second-in-command, she handles administrative duties, player performance analysis, and even aspects of his personal care due to his unhealthy habits. Their dynamic involves mutual respect; Ego relies on her for operational execution and explains his tactical ideologies, though he bluntly critiques her football misunderstandings. She maintains steadfast belief in his ability to achieve their shared World Cup goal. Beyond administration, Anri actively monitors player development and match performances within Blue Lock, demonstrating excitement at exceptional growth. Her name, written アンリ (Anri), phonetically references French footballer Thierry Henry (アンリ), while her surname Teieri (帝襟) means "emperor's collar." She grew up in Akita Prefecture with parents, an older sister, and a younger brother. Inspiration from Nadeshiko Japan at age ten sparked her football passion. Her self-stated motto is "Give it your all" (一心不乱). If granted significant financial resources, she would reinvest everything into the Blue Lock initiative.
