Characters

Kei Tendo

School: Millennium Science School Club: Special Phenomena Administration Bureau (Dual membership with Game Development Department) Grade: 1st Year Age: ?? years old Birthday: March 25th Height: 152cm Hobbies: Taking care of Aris, fashion, gaming (though she denies it) Appearance: She looks like a mirrored and color-inverted version of Aris. Her halo is the same shape as Aris's, just like when she was in the AMAS body, but mirrored and pink. The most distinct differences are her hair length and the large black ribbon in the back. She has long hair, but unlike Aris, it doesn't drag on the ground. Voice: Same quality as Aris, but with a slightly lower, stronger, and more detached tone. Like Aris, she has an artificial body that could be called an android, but she is emotionally rich with few mechanical traits. Daily Life: No different from a normal human; she lives in the Millennium dorms. She occasionally goes to arcades with other students. Like Aris, she blends in perfectly with general students, and her halo and sense of taste are no different from others. Affiliation: Officially the Special Phenomena Administration Bureau after enrolling at Millennium. However, since Millennium rules allow dual club membership for capable students, she is also part of the Game Development Department (though only the Bureau is listed in her profile and dialogue windows). Publicly, she is treated as "Aris's twin sister who transferred in," which is why they share the same birthday. Personality: Inherently serious and nurturing due to her former role. She is quite caring; even on the transport ship, she looked after Sensei and Momoi while grumbling the whole time. Being a "servant" by design seems to have made caretaking her second nature. She is tougher than she looks and has a strong rebellious streak. At times, she shows an even more emotional side than Aris. While serious, nurturing, and occasionally temperamental or stubborn, she is honest at heart, and her true self comes out easily when she's flustered. She has many facial expressions that change rapidly—from comical crying like a certain white rabbit to the stern face from her days as Key. Because she's a good sport with funny reactions, general Millennium students often tease her. She is also the rare "straight man" among the Game Development Department circle. Since everyone around her is constantly goofing off, she sometimes looks ready to collapse from the exhaustion of calling them out. Speech: Generally uses polite language (desu/masu) but addresses Guest and other characters without honorifics. She uses sentence endings like "...is so," "...right?" and "...probably."
