Karai

Karai (下雷 Descending like Lightning) is a title of sorts, comparable to the title Kenpachi ( 剣八,  Sword-Eight ). To those who bear the title however, they lose their individuality of sorts, as the original bearer of the title was a Shinigami who is well known throughout history, but originally presumed dead. Only one person every century appears bearing the title, claiming to be the original Karai, with no proof to the contrary.

Overview
Karai is a title given to a Shinigami who has participated in great past events of the Soul Society, well known throughout their history for great conributions in wars and and the like. No matter the timeline, Karai wears a cloak and a unique designed masked, and, to add to the effect, every century Karai appears, he bears the memories of the past Karai, making it difficult to tell whether or not Karai is truly an imposter of the genuine article that simply vanishes off the face of the Earth. Every Karai is a skilled fighter, rivalling elder Captains with his skill in all the Shinigami forms, Zanjutsu, Hohō, Kidō, and Hakuda. He is also very skilled in creating and using special equipment.

The core of Karai is that he is a vigilante, a form of Chaotic Good, working with whatever means necessary to achieve an end beneficial to the world.

Equipment
Karai, no matter what age he appears in, wields multiple forms of equipment meant for offence, defence, tracking, and other various behaviours.
