Ren Yamashiro

Appearance: Ren is a beautiful young woman with purple hair that has a ribbon on the left side of her hair with square bangs hanging on the right side and violet eyes.

She is dressed in the usual Anti-Demon Corps uniform, shorts instead of a skirt, black tights, white gloves and a cloak and high-heeled boots.

Personality: Both Tenka and Kyouka have described Ren as a patriotic Demon Hunter, doing whatever it takes to defend her homeland ranging from eliminating both Aoba and all the other Humanoid Shuuki who reside in the Hidden Village and working closely with the Prime Minister of Japan to ensure peace.

As noted by Kyouka, Ren is an incredibly curious person. Once she takes an interest in someone or something, it is ill-omen which was noted when Yuuki first made contact with her for the first time. She would find excuses just to spend time with that thing, best seen with the head of the 3rd Unit who was reduced to become her plaything. Kyouka has also noted that Ren tends to treat her curiosities as toys, something to be used acording to her whims whenever she feels like using them. That Yuuki has piqued her interest has frustrated both Kyouka and Tenka. She is also very sharp in her observations of other people and will notice the smallest change in a person's demeanor such as when she inquires to Mira if Tenka has been acting differently due to the latter's discreet investigation of the Anti-Demon Corps' scientific research.

Due to her upbringing, Ren has a strong belief in proving herself superior to others, as well as doing whatever it takes to ensure that people fear her, relishing in the difference between hers and their strengths. She has never met an opponent she is unable to defeat, or had any noted hardship of any kind, finding most things in academics and sports easy to achieve. Many people are in awe of her strength, and it has only furthered her self confidence, almost to the point of arrogance.

Despite her refined looks and demeanour, Ren is shown often to favour using brute force and fear when things do not go her way. The transformation of Yuuki Killer Fang indicates that beneath her refinement is deep malevolence and wrath against any who stand in her way or make her look incompetent. Her fearsome punishments seem to have traumatized, Bell, the Chief of the Third Division, due to Ren's consistent harsh training regarding Bell's failures. Ren's brutality comes out in full when someone refuses to submit to her strength, and is amplified due to a perceived lack of control. Her biggest target turned into Yuuki Wakura after his Killer Fang transformation showed a similar desire to ignore being controlled and began fighting against her, referring him as both a "Bad Dog" and "Beast". She continued using physical force, and almost killed him, after realizing that Yuuki could also regenerate in that Slave Form.

Intelligence, logic, and strength have made her formidable but her sense of power has also made Ren reckless in certain situations. When Kyouka tried warning her about the dangers of the Killer Fang and the rewards she would pay,[6] she ignored them, opting for practical tests to sate her curiosity. Upon understanding how Yuuki obtained his "rewards," and the intimacy they can entail, which included being disrobed and giving kisses; she became embarassed and humiliated, considering the rewards base and beastly. Due to her upbringing, she has had little to no experience with intimacy or having to submit to the whims of another, and by the time she was finished with the experience, she feels so humiliated that she destroys a mountain out of frustration. Her strong feelings of humiliation, shame, and lack of control during the reward, have resulted in her developing a vindictive fixation on Yuuki and a sharp focus on making him submit to her will. She even purchased a dog collar to put on him, to remind him how she towers over all others. She is also beyond stubborn in this goal, even though she can easily humiliate Yuuki by forcing him to be her dog, she still thinks it is not enough of a punishment. Ren has stated that she wants Yuuki to submit when she is giving the reward, or it does not feel like a triumph.

She is also fond of animals, most notably dogs, which Ren stated Yuuki reminded her of, he, in turn, stated that she reminded him of his older sister in spite of them looking different from one another.

Background: Ren was regarded as a genius from childhood who succeeded in everything that she did ranging from academics and sports without failing. Similar to all other woman before her, she gained a unique power after devouring one of the Peaches from Mato. After joining the Anti-Demon Corps, Ren has been described as being the apex of life, as well as Earth's answer by several people despite not using her full powers.

As Chief of the 10th Unit and Commander of the Anti-Demon Corps, she has supreme authoritative rule over the 10th Unit and all the other nine units, even among the Chiefs who leads them. Ren is also noted to be superior in strength among the other Chiefs, being able to overpower Yuuki in his Killer Fang without getting serious.
