About

Yotsugi Ononoki is a character from the Monogatari series, appearing in Bakemonogatari and Nisemonogatari, portrayed exactly as in the original work. Voiced by Saori Hayami. Her signature line is: "Pleased to meet you, Devil Boy—I said with a posed look." A young girl whose (initial) catchphrase is "I said with a posed look." She first appeared in the "Tsukihi Phoenix" arc of Nisemonogatari. Though she looks human, she is actually Yozuru Kagenui's shikigami. She is an apparition—a Tsukumogami born from a corpse that was used for a hundred years. Despite her cute appearance, she is a power-type fighter who uses techniques to enhance her own physical body. However, despite her catchphrase, her facial expressions rarely change. She is a so-called expressionless character, though she does possess emotions (as seen in Tsukimonogatari). She calls Koyomi Araragi "Devil Boy" (Oni no Onii-chan) and sometimes insults him with harsh language, making her a difficult child to pin down. She acted cocky toward Shinobu Oshino, calling her a "senior citizen," but was subsequently put through a terrible ordeal that left her traumatized. In Onimonogatari, she accompanies Koyomi and the others as they flee from the "Darkness." From Nademonogatari onward, she interacts with Nadeko Sengoku (acting as a drawing model and a liaison for a certain person) and calls her "Nade-ko." In Amarimonogatari, it is revealed that as a shikigami herself, she possesses the art of commanding her own shikigami. However, this was apparently a forbidden technique, and she was severely scolded by Gaen-san (it was a technique that normally wouldn't end with just a scolding, so Gaen-san was being quite lenient). Furthermore, she is a character whose personality, including her catchphrases, is unstable. However, her basic setting as a "young girl" remains unchanged. As the story progresses, she begins to call Koyomi "Onii-chan." As a characteristic of the Monogatari series, characters who do not appear on the covers or in chapter illustrations (including the protagonist Koyomi) have no visual image revealed in the original novels, leaving their appearance entirely to the reader's imagination. Consequently, when she first appeared in the anime, her visual design was so eccentric that it drew strong cries of surprise from viewers. In particular, her flashy hair color and bizarre hat left a massive impact, despite having no description at all in the original text. In Tsukimonogatari, Koyomi, who caught a glimpse of her underwear, remarked that she was wearing "panties that would be difficult to recreate on a figure."
