Kyō Ren

is a Human with Shinigami powers. He is also the current Substitute Shinigami of Rider City. Kyō's parentage is unknown, however he is currently a student at the Shintai Sonjuku.

Appearance
Kyō is a mysterious teenager with a light complexion, short black hair, and dark blue eyes. He is a fairly tall young man who has grown muscular due to his training at the Shintai Sonjuku. His mentor, Raian Getsueikirite, has noted that he appears similar to that of a member of the Getsueikirite Clan. In his human form, he prefers wearing large, loose-fitting clothing. In his spiritual form, he wears a variation of the standard Shinigami attire: a shorter, black shihakushō, shinobi trousers, and tabi. His forearms are wrapped in bandages. He also wears a large sheath horizontally on his back to hold his Zanpakutō.

Personality
Kyō was a vibrant and enthusiastic young child. Throughout his childhood, he maintained a position of popularity among his peers. He was known to be energetic and would often get into trouble with his teachers due to his antics. Kyō was also rather outgoing, as he played many sports and was a diligent student at a local dojo, much to the approval of his father.

As a teenager, Kyō's personality drastically shifted shortly after he realized that he was. He faced complete rejection from his father and suffered his mother's death a short time later. The combination of these events made Kyō bitter, anti-social, and rather serious. As the years progressed, Kyō became darker and darker until he met Rin Kimura. Rin reminded Kyō of his younger self and he gradually fell in love with the other boy. Rin was, however, frequently bullied by upperclassmen, causing Kyō to develop a fiercely protective side which would become a staple of his personality. He sought to use whatever means necessary to obtain the power to protect Rin. He attributes his "salvation" to Rin and is confident yet private about their relationship.

Kyō is hinted to be an average student. He has a part time job as a tutor at Rider High School and even helps tutor students outside of his job, suggesting that he enjoys helping others. He is frequently teased by Rin and Raian for having a noticeably terrible, a flaw he acknowledges. He is also known for being extremely blunt, even to the point of rudeness. Jiraiya has noted that Kyō has a calm temperament, but can become explosively enraged if pushed far enough: something he describes as being "scary."

In battle, Kyō downplays his own abilities in order to lure his opponents into a false sense of security. Though he claims to not fight for any particular ideology, he does believe that battles can teach vital lessons. Upon becoming strong enough, Kyō challenged and easily defeated Rin's bullies in order to teach them what it felt like to be completely helpless against a stronger foe in the hopes that it would convince them not to pick on Rin again.

Zanpakutō

Magetsu's spirit is said to be that of a female demon with "ridiculously long" white hair. Kyō has accused her of being sadistic, something he says is proven by the shape of her Shikai form. He also calls her a, a reference to the form he takes in Bankai.
 * Shikai: Magetsu's release command is . In its Shikai, Magetsu elongates to the traditional length of a . The tip of its blade is also more noticeably pronounced in this state.


 * Bankai: : To be revealed.
 * Bankai Armor: While acting as a tremendous defense, Kyō also describes his Bankai's armor as a limiter that keeps his power in check. Should the armor ever be completely shattered, he is able to use what he describes as his "true Bankai."

Trivia
