Yamashiro, Ren

山城恋

Ren is revered by her allies as the apex of humanity. She not only commands the 10th Unit but also holds the position of Head Commander of the entire organization and is considered their strongest weapon.
Ren is a beautiful young woman with purple hair, violet eyes, square bangs hanging on the right side, and a ribbon on the left side of her hair.
She wears the standard Anti-Demon Corps uniform, featuring shorts instead of a skirt, black tights, white gloves, a cloak, and high-heeled boots.
Both Tenka and Kyouka have described Ren as a patriotic Demon Hunter who does whatever it takes to defend her homeland. This ranges from eliminating Aoba and all other Humanoid Shuuki residing in the Hidden Village to working closely with the Prime Minister of Japan to ensure peace.
As Kyouka noted, Ren is incredibly curious. Once she takes an interest in someone or something, it is ill-omened, as observed when Yuuki first made contact with her. She finds excuses to spend time with the object of her interest, best exemplified by the head of the 3rd Unit, who was reduced to being her plaything. Kyouka also noted that Ren tends to treat her curiosities as toys, using them according to her whims whenever she feels like it.
Due to her upbringing, Ren strongly believes in proving her superiority over others and does whatever it takes to ensure people fear her, relishing the difference between her strength and theirs. She has never met an opponent she could not defeat, nor has she experienced any noted hardship, finding most academic and athletic pursuits easy to achieve. Many people are in awe of her strength, which has furthered her self-confidence to the point of near arrogance.
Despite her refined looks and demeanor, Ren often favors brute force and fear when things do not go her way. Her brutality emerges fully when someone refuses to submit to her strength and is amplified by a perceived lack of control. While intelligence, logic, and strength make her formidable, her sense of power also makes Ren reckless in certain situations.
She is also fond of animals, particularly dogs. Ren stated that Yuuki reminded her of a dog, and he, in turn, stated that she reminded him of his older sister, despite their different appearances.
Although most of her past is unknown, Ren stated that she enjoyed looking at maps from remote regions. Her upbringing involved succeeding in everything she did, ranging from mock exams to sports competitions and the student council.
After eating a Peach from Mato and receiving powerful abilities, a previous female President stated that Ren was life's apex and earth's answer.
