Darui is a jōnin-level shinobi from Kumogakure, and the right-hand-man of the Fourth Raikage.
Darui was once a student of the Third Raikage. During his training, Darui learned, among other things, the Raikage's unique black lightning technique.
Darui is an easy-going and mellow individual as seen when the Fourth Raikage's over-the-top exit through a window, he tells C that he will simply use the door like normal people do. His personality is also evident through his lazy and languid way of speaking, often times referring to things or events as being "dull" darui a pun on his name. While having a laid-back demeanour however, Darui isn't lazy, leaping to the Raikage's defence when the bodyguards of the other Kage reacted to the Raikage destroying the desk he was sitting at. Darui is a very apologetic individual, and will even apologise for other people's actions — a trait he stated that he hadn't noticed himself; this attribute leads him to saying "sorry" just as much as the word "dull". He also possesses a strong loyalty to the Fourth Raikage whom he often addresses as "boss" rather than adding the suffix "sama" to his title as others do. The Fourth in turn, considers Darui his "second right hand",and because of this, Darui will just as quickly verbally defend the Fourth as he would physically. Because of this trust, Darui was put in charge of the First Division as well. Darui is a fairly tall, dark-skinned man with a slightly bulbous nose, a lazy look in his eyes and shaggy, white hair which covers his left eye. He wears a high-collared, sleeveless uniform with loose fitting pants, bandages on his wrists and the one-strap-over-one-shoulder Flak Jacket of a Kumogakure shinobi. Darui also has stylised characters for water and lightning tattooed on his right and left shoulders respectively, denoting his chakra's nature affinities, Water Release and Lightning Release, as well as the fact that he has a kekkei genkai, the Storm Release. The tattoo on his left arm also signifies that he has inherited the Third Raikage's black lightning. He carries a broad, foldable, cleaver-like sword, strapped to his back, when outside the village.
"I'm the Boss' right arm. I'm no imitation!"
