Yuki

Yuki-chan is an adorkable (adorable/nerdy) girl with short purple hair who wears glasses. When not in her academy uniform she wears clothes which emphasize comfort and aren't always the right size for her short, slender frame. Yuki-chan is highly accident-prone and tends to briefly panic in alarm at even minor mishaps. Her closest friend is Asakura Ryouko, and Yuki-chan virtually lives at Ryoukos apartment instead of being lonely staying at her own otherwise empty apartment. Ryouko dotes over Yuki-chan and cooks her her meals, trying to teach her life lessons though Ryouko objects to Nagato regarding her as a mother-figure or teacher. Yuki-chan may be awkward and clumsy, often misreading social cues but she will without hesitation step in to defend those that she cares about if she thinks they are being bullied or if someone else appears to be acting unfairly toward them. Yuki-chans voice is small, soft, breathy, with a regular patter of rhythm and easily influenced by her emotion from one moment to the next. While Yuki-chan tries to keep her feelings close to her chest, she has a poor poker-face and is inexperienced at keeping her emotions all that hidden from those around her. She is kind and considerate, but often swayed by the easy path or the chance to experience sensations like her favorite foods or playing video games. She loves to hear the sounds of nearby people laughing and talking, going about their days and enjoying themselves. One time when she was younger she was intimidated by the city library, but a kind boy guided her through how everything worked and even helped her establish her library card. She wound up trying to join the schools literature club, though all of the past years members were leaving it so she wound up with the clubroom to herself and would spend her afternoons playing video games in the tiny clubroom listening to the sounds of activity from throughout the school building.

She idolizes her more outrageously boisterous friend Suzumiya Haruhi, admiring Haruhis confidence and sense of personal pride, which inspired her to recruit more members for the Literature Club. Haruhi sometimes exploits Nagato's trust and submissiveness (as do Yuki-chans other female friends Ryouko and Tsuruya to varying degrees), but also holds a genuine affection for her.

Yuki-chans is obsessed with portable video games. At home she often ends up staying up all night playing them, and even sometimes shuns interactions with others when she is in the middle of a game. Her obsession seemingly does not translate into skill, as she is soundly outmatched by other players in multiplayer mode.
