Iriga Kunori

Iriga Kunori was the elder brother of Kai Kunori and former member of Konohagakure's Torture and Interrogation Branch of ANBU. A true master in the field, Iriga's reputation exceeded him, and his abandoning of the Leaf Village was greatly frowned upon, given the fact he held great potential to become the head of the ANBU branch. Later reports of tortured and mutilated bodies forced the Leaf Village to place Iriga in the bingo book, fearing for the worst.

Biography
He was named a prodigy among his classmates and a promising shinobi of the Leaves. However, a series of unfortunate events that resulted in the deaths of Iriga's teammates and sensei while on a mission resulted in Iriga holding an inner desire for revenge. His progression in the art of torture and interrogation through the understanding of the human anatomy allowed Iriga to progress through the ranks, obtaining the rank of jonin and admittance into the ANBU.

It was inferred that Iriga grew frustrated by the work he received in the ANBU and soon left, presumably to seek out the killers of his teammates years ago. More years passed, and it seemed that Iriga did not find the killers, though reports seem to indicate that he teamed up with Akatsuki. Without his intentions for doing so known, Konoha deemed him a threat and placed him on the international bingo book as an S-rank due to rumors of mutilated corpses being of Iriga's doing.

Behind the scenes
As the second character ever created by LaviBookman, Iriga was written to be the antithesis of Kai. On deviantART, where he was conceived and brought into role-play, he started out as a typical member of the Akatsuki. The resignation of the organization's leader's player placed Lavi's character into the leadership position, making Iriga the fastest developed character, power-wise, of Lavi's early role-playing years. This development brought responsibilities that left Kai Kunori in the shadow of Iriga's growing influence. Surprisingly, Iriga did not develop as many gary-sue qualities as the ones that were developed in Kai.

Iriga's development marked the first time Lavi experimented with sentient swords, the latest version currently possessed by Takeshi Higashinuma of the Seven Swordsman, without the sentient qualities.
