The mother of Sengoku Nadeko. Not much is known about her, though Deishuu Kaiki states that she doesn't know much about her daughter. On top of that, she likely forces expectations on Sengoku, such as being cute.

Second season of the Monogatari Series, part 1/2. Contains the arcs Tsubasa Tiger, Mayoi Jiangshi, Nadeko Medusa, Shinobu Time, and Hitagi End, from the Nekomonogatari White, Kabukimonogatari, Otorimonogatari, Onimonogatari and Koimonogatari light novels, respectively.
 
These stories take place after the end of the summer vacation when the apparition of the bee had left and the apparition of the phoenix avoided any consequences… Now that Koyomi Araragi and the girls were entering their new school terms, they were once again about to encounter supernatural beings…but this time, they may not be so easy to deal with.
 
Tsubasa Hanekawa, Mayoi Hachikuji, Nadeko Sengoku, Shinobu Oshino, and finally Hitagi Senjougahara. The girls’ loneliness, their confessions, and their departures… 5 new “stories” begin now.

Circling back to a middle school girl’s apotheosis, if we can call it that, in OTORIMONOGATARI, and the mortal threat it poses to the hero and his girl, this “Season Two” finale is narrated, for the first time in the series, by a grown-up—but if the word conjures a sense of reliability, of stability and certainty to you, dear reader, then the lesson to take home from this is to trust no one.
 
Because the teller of the tale, who has been summoned by the heroine to defuse the situation, despite having been her nemesis since the very outset of the series, is—in the absence of the equally shady adult, Oshino, who at least was an expert—none other than his college frenemy, the fake ghostbuster who doesn’t believe in ghosts, the shameless swindler Deishu Kaiki.
 
And it is indeed a con that he agrees to perpetrate, uncharacteristically pro bono, on a wrathful god—a mythic undertaking if true, which it may be, when a liar among liars holds that his story, like any other, is all a lie. But maybe not, when a man who claims to be wise in the ways of the world sounds just as self-conscious as his adolescent counterparts or a Russian anti-hero.
