School: Millennium Science School Club: Paranormal Affairs Special Team Gender: Female Age: Unknown Height: 152cm Weapon: 'Luminous Nova' (Railgun) Hobbies: Taking care of Aris, dressing up, gaming She has a somewhat cold and blunt personality. While she seems indifferent, her expression of emotions is quite distinct. She often nags and snaps, but she is a tsundere who deeply values and looks after her friends. She is an android, not a human. Despite being an android, she feels emotions and experiences biological phenomena, making her not much different from a human. She is exceptionally kind to Aris and tends to be overprotective of her. Although officially part of the Paranormal Affairs Special Team, she spends all her time in the Game Development Department. Initially, she had a stiff and cold personality like Aris's early impression, speaking in a business-like tone. She also calls Aris 'Princess.' While she used to thoroughly ignore anyone other than Aris, her words and actions now carry emotion. Though her way of thinking remains the same, she has solidified into a tsundere who looks out for and cares about those around her, even while acting grumpy. She speaks politely.

School: Millennium Science School Club: Game Development Department Age: ??? Height: 152cm Birthday: March 25th Hobbies: Gaming (RPGs) Speech Style: Uses polite language and refers to herself in the third person. Gender: Female Weapon: A massive 180kg railgun called Super Nova, which Aris calls the Sword of Light. Since she is a robot—an android—rather than a human, her age is unknown. She often makes game-related jokes, saying things that suggest she doesn't distinguish between reality and fiction, or quotes game dialogue directly. In the beginning, she spoke in an emotionless, machine-like tone and seemed unfamiliar with the outside world, but after learning common sense (albeit haphazardly) through games from the Saiba sisters, she lives her daily life without much trouble.
