Fuuka Yamagishi, a reserved and timid second-year student at Gekkoukan High School, joins the Specialized Extracurricular Execution Squad. Targeted by bullying from classmates like Natsuki Moriyama, she suffered an incident where Natsuki locked her in the school gymnasium. This led to her accidental entrapment within Tartarus during the Dark Hour, where she survived alone for ten days before SEES rescued her. This traumatic experience awakened her Persona ability, summoning Lucia. Following her rescue, Fuuka takes over as the SEES navigator from Mitsuru Kirijo. Her Persona abilities focus exclusively on analysis and support. She provides critical tactical assistance by scanning enemy weaknesses, forecasting boss locations, monitoring party status, and offering real-time battlefield commentary. Her skills reveal enemy affinities and skill sets, with later abilities like Healing Wave restoring party HP during Tartarus ascension. A second Persona awakening on October 20th evolves Lucia into Juno, granting access to the Oracle skill. Oracle delivers random effects, including full HP/SP restoration or curing ailments, but carries potential risks. Fuuka undergoes significant personal growth. Despite her trauma, she forgives Natsuki for the bullying and protects her from Shadows, facilitating their reconciliation and eventual friendship. Her time with SEES fosters increasing self-assurance and willpower, transforming her from a withdrawn victim into a resilient and compassionate individual. This development is tested after Shinjiro Aragaki's death in October; she experiences guilt over his sacrifice but gradually recovers with teammate support. Natsuki's subsequent school transfer presents another emotional challenge. She possesses a strong affinity for technology and computers, frequently working on her laptop in the dormitory. Fuuka demonstrates advanced hacking skills, accessing restricted Kirijo Group files to uncover Tartarus truths and reconstructing deleted video messages. Her interests include hard science fiction, reflecting her analytical mindset. However, she struggles with traditionally feminine activities like cooking, often making ingredient mistakes despite attempts to improve. Her family background fuels her insecurities; her parents, from a family of doctors, impose academic pressure stemming from their own inferiority complexes. This creates a stressful home life, leading Fuuka to prefer the SEES dormitory where she feels valued and useful. Visually, Fuuka has short teal-blue hair. She typically wears Gekkoukan High's winter uniform with a teal-green patterned turtleneck, white tights, and brown loafers. Her casual attire features a light green poncho over a black turtleneck, a knee-length skirt, black leggings, and ankle boots. Within Tartarus combat scenarios, she utilizes radio headphones for communication. Beyond navigation, Fuuka represents the Priestess Arcana, symbolizing her contemplative nature, independence, and desire to connect people, reflected in her belief that her Persona grants "the power to connect people, even when they’re apart."
