Jun Shirakawa

Jun Shirakawa serves as a supporting character later turned supporting antagonist of the manga Juujika No Rokunin. He is the elder brother of Kaname.

Personality:
Jun Shirakawa first appeared to be a friendly, energetic, and fun-loving individual. However, after the incident where his little-sister was raped and witnessing her coming out of the hotel with Uruma, he completely changes, Jun starts to become extremely paranoid and not long after he was manipulated by Kyou, he completely lost all of his emotions.

Trivia:

 * The initial appearances of Jun and Anzai Zenichi are very ironic. While Anzai is a false antagonist revealed to be a hero all along with enough knowledge to understand the situation Uruma is in, Jun is a supporting character who seems to be obsessed with his sister's safety his entire life to the extent that he becomes an antagonist towards Uruma later on.
 * While Jun may have became one of Kyou's allies, it is only because of the false belief that Uruma was responsible for his sister's tragedy, even though ironically, he is supporting the same person who trained one of the monsters who attacked his sister, with his enemy (Uruma) ironically being the one to avenge his sister.
 * Based on the new allies Kyou rallied up against Uruma, there might be several more arcs of the manga before Uruma may finally have the chance to confront Kyou. Because of this, this strongly implies that Jun may have an arc of his own before the Kyou arc. However, this may be uncertain as to whether the mangaka is planning on creating several new arcs or is simply sticking to the same arc in which Uruma has to defeat some of Kyou's goons (similarly to how he defeated Yuuga's goons before confronting the mastermind himself) in order to get to Kyou himself...
