Ren Yamashiro

Personality: Ren Yamashiro (山城 恋やましろ れん, Yamashiro Ren) is the Chief of the Anti-Demon Corps' 10th Unit and a major supporting character of the Mato Seihei no Slave anime/manga series.

Revered by her allies as the apex of humanity, Ren not only commands the 10th Unit but also holds the position of Head Commander of the entire organization and is considered to be their strongest weapon.

Ren is a beautiful young woman with black 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, black pantyhose and a cloak and high-heeled boots.

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. Powers and Abilities: 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. Peach Blessing: Vairocana: Her Peach Blessing, which allows her to use the abilities of all eight Buddhas depending on the mandalas that are placed on her pupils, in addition to a manifesting a light ring, which has several cards circling all around her. Ren can activate her two abilities at the same time, as well as being the only who knows what all her abilities are. She is afforded flight and levitation, being able to make her chair float and covering vast speeds in seconds;[15][16] releasing shockwaves from kicking; negating other Peach Blessings; and teleporting people vast distances, such as the bottom of a distant sea, but unlike Tenka's ability, she cannot use it on herself. However, even this ability can’t negate the “rewards” requirement to use the “Slave” ability. Killer Fang: The Slave Form, which Yuuki entered after Ren acted as his Master, which Kyouka stated was a dangerous form that she hadn't seen before. This form allowing him to instantly kill several Shuuki in a single strike. Despite its offensive power, he fights in a more berserk manner and would even go against the person riding on top of him. It is likely more demonic than previous forms due to Ren's more cruel personality polluting him compared to other riders having more pure emotions. Sacrificial Goat: This is a special technique, where Yuuki causes countless symbols featuring fangs appearing above his intended target's heads by flashing his eyes, after that he make a bite which causes all their upper bodies to explode as if they'd all been bitten. However, the attack can be stopped if Yuuki is prevented from closing his mouth. Physical Abilities: Immense Strength: Ren has immense strength above what her feminine build suggests. With even the simplest moves such as beating or slapping her opponents, she could decimate, if not killing them using a couple of blows. As a testament to her strength, she was capable of trading blows with Yuuki in his Killer Fang state without using Vairocana to the point of beating him to a pulp before he regenerated. She can easily overwhelm two Thunder Gods with her strength alone in which the other God is also known for her immense strength (albeit the two Gods seemed to be not serious). Immense Speed and Reflexes: Ren, in addition to her strength has impressive speed and reflexes, is capable of deflecting bullets fired at close proximity using a single hand. When Yuuki, in his Killer Fang form used Sacrificial Goat against her, she instantly closed the gap between them and incapacitated him before the technique took place. She can take on two Thunder Gods at the same time and overwhelming them with her speed which forced them to retreat. Master Martial Artist: Ren is an extremely capable fighter. Using her tremendous speed and strength, she is capable of dealing lethal kicks and punches to knock down her opponents.

Shuuki (醜鬼, Shūki), but their official name is Yomi Shuuki (黄泉醜鬼, Yomi Shūki) are the dominant beings who live in Mato. Shuuki, in general, are all ferocious creatures who stand taller than an average adult male with numerous shapes and builds, most having an almost dark skin tone and texture that resembles raw muscles while their faces are pure white in color, the misshaped face appearing to resemble a grotesque mask. All Shuuki have monstrous features all ranging from far darker skin tones, some being larger than average Shuuki, exposed bones, multiple arms, eyes, and arms. Following the appearance of Mato, all the Shuuki have shown to be ferocious and aggressive toward all humans, attacking several towns and areas, which results in the brutal deaths of several humans after passing through the Gates. No humans were capable of combating the Shuuki until the Peaches were discovered, resulting in the creation of the Anti-Demon Corps and Onmyou Agency.
