Alice Shimada, nicknamed Arisu, commands the All-Stars University Team’s Sensha-dō unit as a 13-year-old prodigy. Heir to the Shimada family’s tankery legacy, she employs her mother Chiyo’s "Ninja Tactics"—unorthodox strategies contrasting the Nishizumi style. Her academic brilliance propelled her into university early, isolating her socially despite her tactical prowess. Shy and introverted, she communicates through precise hand signals and footwork, leading remotely before diving into combat personally. A pivotal deal with her mother drives her clash against Oarai: victory would secure Shimada sponsorship for the endangered Boko Museum, reflecting her devotion to the mascot. Piloting a Centurion Mk. I A41, she neutralizes ten enemy tanks, the match’s highest tally, before falling to Miho and Maho Nishizumi’s combined tactics. Post-battle, she gifts Miho the cherished Boko plushie she once struggled to accept, cementing their rivalry-turned-respect. Though defeated, her mother sponsors the museum unconditionally. Alice transfers to St. Gloriana Girls’ Academy, seeking normalcy while contributing her Centurion to their tournament wins. In the OVA "Arisu War!", she joins Oarai’s group activities, bonding with Miho over shared Boko enthusiasm and motion sickness remedies during a sleepover. Supplementary materials detail her fondness for frilly attire, dislike of cheese and tomatoes, and a dorm adorned only with miniature Boko figures. Born October 24—a date marking historical naval losses and the UN’s founding—her spin-off appearances showcase gradual social growth: donning Boco-themed pajamas, engaging peers with shared interests, and shedding earlier solitude for budding friendships. Across media, her evolution from a duty-bound tactician to a quietly connected teammate underscores her nuanced arc.
