Shinku Dairenji is Miria Honda and Nayuta Mitsuari's closest friend. She is a Japanese Ukrainian agent of the Foo Fighters, she was raised in France in a top secret research lab. She provides basic combat training for new recruits of the Foo Fighters and fellow Wizard Saint candidates. She once was a brain-washed hitman for the Dairenji Syndicate when she was younger along with her sister, Ryouka. She killed her father after Ilona freed her from the #1 Wizard Saint's Black Attraction magic which Shiro was using to control her.
Shinku along with her younger sister, Ryouka, were conceived through artificial insemination using the seed of Shirō Dairenji in demon-possessed vampire.
Shinku has a tall, curvy figure that is very voluptuous and muscle-toned, fitting for a seductive vampiress-demoness hybrid. Shinku has a lightly tanned creamy skin complexion and steely crimson eyes. Her hair is a dark-brown color of back length that is pent up slightly in the back by her red ribbon that has golden stripes on the ends. She wears a skimpy and highly decorated red furisode kimono that hangs off her shoulders and exposes her cleavage with bandaging covering the lower half of her exposed breast, with a floral decorated black obi. She a black and white horn on the left side of her head and a metal demon surprising collar around her neck. She wears black thigh high sheer stockings and sandals, with risqué panties.
Shinku wears a multitude of casual clothes, ranging from sleek and sexy, to very thin and revealing. However, she usually wears her school uniform, a sailor fuku which consists of a pure white blouse with its sleeves rolled to her elbows. The ribbon of the uniform is crimson red and is tied in the front and laced through a loop attached to the blouse. The bottom is a blue pleated skirt. She wore it with black knee high socks and black shoes.
Though very pretty, she is extremely ruthless, sarcastic, powerful and cold-blooded, so much so that even Estelle is terrified of her. Due to her fighting ability, she is able to protect her sister by herself. Despite this, Shinku is still feminine by nature and has a weakness for anything cute. Her dream is to be "the strongest being in history". She can quickly become extremely violent, killing an "enemy" on sight, but immediately regrets sending "another innocent soul to the darkness". She finds this has become a bad habit for her. Her great intelligence and skill made her father favor her, but she hates the Dairenji Family.
She doesn't put much emotion into her words. Shinku is slightly perverted and enjoys teasing others at any opportunity. Shinku also is quite apathetic and dry-humored as she doesn't find much motivation in her line of work. She generally tends to smirk before teasing or performing her antics at others, putting them in uncomfortable situations. She also is very elegant in her movement.
