Going by the self-chosen name 'Alice' and identifying as female, Nagi Arisuin is one of Hagun Academy's most enigmatic first-years. Her innate device, known as 'Shadow Hermit,' grants her extraordinary dominion over darkness, earning her the fearsome title of 'Black Alice.' Dispatched as a sleeper agent to surveil Shizuku Kurogane, Nagi's inherently compassionate nature leads her to become a nurturing confidante to those around her. Torn between cold organizational directives and the warmth of genuine friendship, she ultimately chooses to protect those she holds dear.
