Kosane Kiriha (霧羽こさね) is the protagonist of Null Magical Girl. She is an unemployed graduate student attending university to pursue a Master's degree, where the title of her Master’s thesis is “A Study of the So-Called Cognitive Revolution.” Ten years ago, Kosane attempted to make a contract with Kyubey, but the process failed as she didn't possess a soul (and later discovers she doesn't have a brain either). Despite this, she is paradoxically considered to be both a magical girl and not one.

In Null Magical Girl

In Null Magical Girl, Kosane acts as the main character. Additionally, the story is told primarily through a first-person perspective.

Powers and Abilities

Kosane herself doesn't have any supernatural abilities like other Magical Girls, but instead is a prime candidate for genetically engineering by Kyubey. Because of Kyubey, Kosane lost the human ability to read emotion and also gained the power of flight for a short time.

Etymology

'Kosane' is likely a reference to The World of Null-A - the novel's main character's surname, Gosseyn, is stated to be pronounced "go sane" by the book's author. This is also confirmed by another tweet by Gengen Kusano.
- "Kosa" (こさ) is similar to the term ごさ (an alternate writing for kanji meaning "error, discrepancy").
- "Sane" (さね) is an alternate writing of kanji that means "truth" or "reality".
- Moving the last syllable to the front like Eruna's name (but excluding "-sa") creates "neko" (ねこ), an alternate writing of kanji meaning cat. If intentional, this may reference Incubators and/or Coeurl (named after a cat-like creature similar to Incubators).
Her surname Kiriha (霧羽) is comprised of kanji 霧 ("mist, fog") and 羽 (originally referred specifically to where the quill of a feather attaches to the skin, then broadened to mean "feather", and then further to "wing").
