Kisaragi Jin BlazBlue Images

Jin Kisaragi is a Major and 4th Thaumaturgist Squadron Commander of the NOL, and Ragna and Saya's brother. He is a playable character in Calamity Trigger and Continuum Shift. Jin also serves as the rival character of the series.

When Jin was a little boy, he was very dependent on his older brother, Ragna, for affection and constantly pestered him to play with him. He saw his sister Saya as an obstacle of getting his brother's attention and constantly bullied her in retaliation. Eventually, Ragna decided to look after the sickly Saya and distanced himself from Jin, thus increasing his jealousy.

It was then Terumi Yuuki entered Jin's life and told him about The Black Beast, that it would be born from Ragna, and that he is destined to destroy it. Deciding that his brother must pay for his ignorance, and to get rid of the obstacle between them, Saya, Jin left Terumi to do as he pleased, including burning the church where they stayed and murdering their caretaker. When Ragna arrived, he only watched in shock as Terumi cut off his arm, and kidnapped Saya. Jin later vanished from Ragna's life, and apparently his memory of that incident was blocked off.

Jin was later adopted to the high-esteemed Kisaragi family. With his talents, he rose up in the ranks of the NOL and was given the Nox Nyctores, Yukianesa, (however, in the true ending of CS, he tells Ragna that Saya is the one who actually gave him the sword) but his other siblings never trusted him, thinking that he only got his ranks due to his adoption. Indeed, Jin himself felt completely empty even after being showered with awards and ranks (which included the stopping of the Ikaruga Civil War).
