Kagenui, Yozuru

影縫余弦

Yozuru is a woman with black hair and red pupils. Her hair is cut into a bob with red streaks and is accessorized with a bird-shaped hair clip. She wears a khaki shirt over a black collared top, which features the same bird motif as her hair clip, along with dark red pants held up by suspenders. Her footwear consists of black high-heeled sandals.
She is a professional onmyouji and attended the same university as Deishuu Kaiki and Meme Oshino. The three are known to be constantly together as members of the university's occult research club. Among the trio, she is the one who prefers to stand for justice. Of the three university students, she was the only one to graduate. Yozuru is a rather famous figure in the supernatural realm, to the extent that Shinobu Oshino, herself a very powerful oddity, refused to divulge any information about her as a form of respect. She speaks in a Kyoto dialect and is described as having native-level expertise in it. She also has an unusual quirk of avoiding stepping on the ground, as if playing a game where the ground is a sea filled with sharks. She maintains this quirk at all times and would even use her familiar, Yotsugi Ononoki, as a platform if needed.

Spoiler

She fights using her fists and is powerful enough to punch through multiple floors at once. Unlike Meme, Deishu, and Gaen, she works for free, meaning she only hunts and kills oddities because that is what she truly wanted. Yozuru calls herself "Japan's first battle onmyouji." She is sadistic and brutal, choosing to specialize in exorcising immortal beings because nothing else presents a challenge to her. Although she considers herself an ally of justice, her ideology is based on exacting justice by eliminating those who should not exist (immortal oddities) and disregarding the consequences of such acts. To her, immortal oddities have no place in the world. Despite this, she has a considerate side as well, seeing people like Koyomi as human despite their contact with an oddity. According to Koyomi himself, Yozuru reminds him of Meme somewhat. Yozuru uses her judgment to decide which immortal kais to fight and hunt by separating them into those that are alive forever and those that are dead forever. She then hunts kai that are considered alive forever, which is why Yotsugi is her assistant, as Yotsugi is technically not alive.
While Koyomi was fighting her, he counted how many times she punched him while breaking through the floors—he counted almost 500.
