Overview
Otose Kotama is a third-year student at Millennium Science School and a key member of the hacker group Veritas in Blue Archive. Serving as the club's eavesdropping and audio reconnaissance expert, she possesses exceptional skills in communications monitoring and signal analysis. While socially awkward and soft-spoken in person—addressing even younger students with formal honorifics—she exhibits a sharp-tongued personality online. She spends much of her spare time collecting ambient sounds and monitoring communication channels.
Appearance
Kotama features long straight blonde hair styled with side braids and hair clips, paired with purple eyes and semi-rimless black-framed glasses. She wears large headphones over her ears. Her standard outfit includes an open long-sleeved jacket, gloves, and boots. Her halo is light purple, consisting of two concentric circles with two long needles pointing toward 45 and 225 degrees and two short needles toward 135 and 315 degrees. Variations include a winter camping outfit with a scarf, vest, black tights, and short boots, as well as pajamas.
Personality
In the physical world, Kotama is quiet, introverted, and unfailingly polite, addressing everyone with formal speech regardless of seniority. Despite her reserved demeanor, she harbors an intense obsession with wiretapping and collecting ambient audio, particularly white noise and recordings of Sensei's voice to craft personal ASMR tracks. She leads a sedentary, game-focused lifestyle with remarkably low physical endurance, often exhausting herself quickly during outdoor activities. However, her motivation spikes whenever a unique sound recording or wiretapping opportunity arises. Deep down, she is devoted and caring, expressing genuine concern whenever she suspects Sensei might be in trouble.
Abilities
Kotama wields a specialized suppressed handgun named Echo Link, designed to minimize noise during operation. In her standard configuration as a SPECIAL supporter, her EX skill, Start Listening, applies a wide-area attack power boost to allies. Her normal skill deals damage to a single target every 30 seconds while decreasing the target's attack power, and her sub skill provides a continuous passive attack boost to all party members. In her Camp variant as a STRIKER, her EX skill involves throwing a bear repelling bell to damage a target and inflict the confusion status condition for up to 11.5 seconds.
Background
As a prominent hacker within Veritas at Millennium Science School, Kotama regularly assists allied clubs, providing cyber intelligence and back-end support during conflicts involving Seminar and C&C. In her daily life, she frequently attempts to conceal wiretaps inside Schale's office inside stuffed animals or clocks to get closer to Sensei, though her schemes are regularly foiled. During the Cyber New Year's March event, her extreme indoor gaming habits prompted Kagami Chihiro to drag her, alongside Omagari Hare and Konuri Maki, on a mandatory winter camping trip, where she utilized the outing to record rare natural soundscapes.
Relationships
Kagami Chihiro serves as Kotama's superior in Veritas, frequently reining in Kotama's illicit eavesdropping activities and forcing her into healthier outdoor habits. Konuri Maki and Omagari Hare are her fellow Veritas clubmates and close gaming companions who share her nocturnal online habits. Toward Sensei, Kotama harbors a profound attachment, frequently attempting to plant listening devices, track locations, and store voice recordings, though she deeply respects Sensei's guidance and relies on their mutual bond.
Trivia
Kotama's signature handgun, Echo Link, is visually modeled after the Austrian Glock 19 semi-automatic pistol, chosen for its compact frame suited for covert reconnaissance. Upon the game's initial release, her recruit dialogue incorrectly referred to her school as Millennium Academy, which was later patched to the official Millennium Science School. In the cafe, placing the Outdoor Partition furniture item triggers a unique interaction animation where she leans against the barrier to eavesdrop on adjacent sounds.
