Description
Alice Tendō, originally designated AL-1S, is a mysterious member of Millennium Science School's Game Development Department. Her origins remain unknown; she was discovered within an abandoned Ruins munitions factory with no retrievable data on her background or age.

Initially exhibiting robotic speech and behavior, prolonged exposure to retro video games with department members Yuzu, Momoi, and Midori profoundly shaped her development. She adopted distinctive game-inspired speech patterns and mannerisms, displaying traits akin to "chuunibyou" syndrome that manifest as frequent quotations from classic games in her conversations.

Physically, she possesses extremely long, glossy black hair cascading to the floor, styled with a headband and clip on her left side. A distinct long bang falls centrally between her eyes. Her pale skin contrasts with glowing blue eyes resembling camera lenses. Her halo manifests as an abstract arrangement of cyan blue squares and rectangles.

Her attire consists of a modified Millennium uniform: a white and blue hoodie over a tucked-in white shirt with a blue tie, paired with a black pleated skirt, woolly socks, and white sneakers with gray laces. Notably, her Millennium access badge was artificially crafted by Veritas, and her clothes were hand-me-downs from Midori.

Her primary weapon is a white railgun prototype supplied by the Engineering Department. It features a yellow core, blue receiver and accelerator, an LCD screen indicator, and protective front covers that open during firing. Millennium insignia and Game Development Club logos mark the weapon.

Her combat capabilities include the EX-Skill "Collapsing Worlds!", dealing percentage-based damage in a straight line with damage multipliers scaling with Energy charge levels. Her basic skill "Hailing Light!" periodically boosts critical hit rate and Energy charge levels. Passive skills enhance attack power ("Enhanced Magic!") and critical hit rate during EX-Skill use ("Awakening Supernova!"), both scaling with Energy charge levels.

A significant aspect of her background reveals her as the "Princess" (王女) of the Nameless Gods. She also harbors an alternate identity known as Key (ケイ), an artificial intelligence programmed by Nameless Priests to guide her in executing a genocidal campaign.

Within the Game Development Department's collaborative activities, she notably joined Momoi and Yuzu on a rescue mission when Midori was kidnapped. During the confrontation with antagonist forces, she employed a powerful ability referred to as "Blinding Light" to combat adversaries.
