Kozue Orihara

Kozue Orihara is a girl who transferred in Suimei Academy’s second year class, the same as Takumi Nishijou. Kozue has the unique ability to talk to people with “the voice of her heart”. She cannot speak verbally due to extreme shyness. Kozue is short, younger-looking, and relatively flat-chested, looking like a middle school girl instead of high school student. She wears her long, yellowish orange hair in two curly pigtails, and always wears her school uniform. Kozue’s most defining trait is her inability to talk, which she makes up for with her telepathic abilities. Outside of school, she’s usually seen with Sena Aoi after she moves to Shibuya. Kozue is much friendlier than Sena, and offers Takumi a chance to join up with her and Sena to try to defeat N.O.Z.O.M.I.At school, Kozue always seems quiet and on the verge of tears, but when she's talking in her head to Takumi or Sena, she sounds bright and chipper, and Takumi often remarks that she sounds like an anime character. Her childish, cutesy manner of telepathic “speech” sounds somewhat similar to Faris NyanNyan from Steins;Gate except without sounding like a cat. She also attaches the sufix “-shan” to people's names (probably a hybrid of chan and san). Her character song for ChäoS;HEAd NoAH, Recognize the Tiny Voice, features her typical mispronunciation, mispronouncing “kizuite” (the verb for “recognize”) as “kidzuite”, right in the title. Despite her cheeriness, though, she often telepathically “says” very disturbing things. She said that the reason she had to get her hands on a DI-Sword was “So the bad men would go slashy-slashy boom boom!”. And if someone threatens her or anyone she knows she says, in a chipper voice, “I'll kill you!”. Although she seems upbeat, she is extremely disturbed and broken, with a desire to kill people. She has a similar personality to Illyasviel von Einzbern from Fate/stay night, another girl who seems mostly innocent and pure but also has a desire to kill.
