Darui

is a jōnin-level shinobi from Kumogakure.

Personality
Darui is an easy-going and mellow individual as seen when the Fourth Raikage's over-the-top exit through a window, he simply tells C that he will just use the door. His personality is also aptly displayed through his through his lazy and languid way of speaking, often times referring to things or events as being — 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 had never noticed himself; this attribute leads him to saying just as much as the word "dull". He also possesses a strong loyalty to the Fourth Raikage whom he often addresses as, 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.

Appearance
Darui is a fairly tall, dark-skinned man with a slightly bulbous nose, a lazy look in his eyes and white, shaggy 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 and  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.

Abilities
Darui is a highly skilled and capable shinobi. He learned how to create black lightning under the tutelage of the Third Raikage, making his lightning-based techniques even more powerful. His chakra reserves are great enough to not die of chakra exhaustion after using three of the Treasured Tools of the Sage of the Six Paths and still had enough chakra left to continue fighting. His abilities have earned him the praise and recognition of the Fourth Raikage himself, who appointed Darui as his personal bodyguard and considers him his right-hand man. He is also quite smart, as noted by Kinkaku. This was witnessed in his uncovering the mechanisms of the Treasured Tools during his battle with the Gold and Silver Brothers.

Kenjutsu
Usually, Darui wields a broad and fairly long sword that is peculiar in comparison to others swords in that it folds in two to be sheathed and unfolds when in use. He has shown exceptional skills in kenjutsu, as he was able to clash with Suigetsu Hōzuki's Kubikiribōchō and easily overwhelm and pin him to a wall with his lightning-imbued sword. He was also skilled enough to literally disarm Ginkaku and Kinkaku during their battle, and knock Ginkaku into Kinkaku's Kōkinjō while quickly seizing the Shichiseiken and Benihisago.

Nature Transformation
Darui is proficient with water and lightning release techniques, and is able to use two separate techniques of the natures simultaneously. He uses Lightning Release: Wave of Inspiration, together with water release techniques to let electricity flow through the water, making the technique deadlier. He is also able to combine these two separate natures to create the kekkei genkai known as Storm Release which creates beams of light that flow like water and can be freely guided like missiles.

He is also able to use black lightning — a special form of lightning passed down to him by his teacher, the Third Raikage. With the power of the "black lightning", he can use techniques such as the Lightning Release: Black Panther to immobilise and or kill several enemies. According to one of his comrades, he is the only person to have inherited the Third Raikage's technique.

Darui is also proficient with the use of chakra flow with ballistic weapon. His skill with chakra flow is such that he was able to cut through a metal blade with a lightning-enhanced shuriken.

Five Kage Summit Arc
Darui and C were chosen to escort the Fourth Raikage to the Kage Summit in the Land of Iron. Shortly after they arrived and the meeting began, Darui and C had to rush to the Raikage's defence following his outburst and subsequent destruction of the table he was seated at, blocking the attacks of the other Kage's bodyguards whom had interpreted this as an aggressive action towards their own Kage. They return to their posts after things settled down, only to again come to the Raikage's side when White Zetsu appeared later during the meeting. Zetsu reveals that Sasuke Uchiha, Killer B's captor, was nearby, so Darui and C accompany the Raikage to track Sasuke down. When the Raikage broke down a wall to leave, Darui comically apologised for it and the table before departing.

When they locate Sasuke and his team, Suigetsu charges at C. Darui however, intercepted his attack and the two men exchanged blows with their respective swords. Darui was ultimately victorious, as he imbued his sword with lightning-natured chakra and pinned Suigetsu to a wall. He then tended to C — who had been knocked unconscious by Sasuke's genjutsu — and they both watched the Raikage grow increasingly reckless in his fight with Sasuke. The Sunagakure delegation soon arrived to provide assistance, and Darui joined forces with them to bombarding Sasuke with a devastating attack. Using Susanoo, Sasuke survived their assault and destroyed the pillars that supported the building causing the roof to collapse; Darui is protected from falling debris by the Fifth Kazekage. Darui and C reunited with the Raikage and they returned to the summit hall, where Tobi explains his Eye of the Moon Plan to them. As part of his explanation he revealed that B only pretended to be captured, Darui stated that this revelation did not surprise him at all.

After the formation of the Allied Shinobi Forces, Darui joins the Raikage in searching for B. They were drawn to the site of his battle with Kisame Hoshigaki and arrived just in time for Darui to stop Kisame's attempt to cut off B's legs breaking the Supervibrato Lightning Release Swords with a lightning-infused shuriken. When "Kisame" was eliminated, they all returned to Kumogakure. Despite Darui's desire to rest, Mabui‎ requests a report of what has happened since they left. Darui later attended a war council meeting.

Shinobi World War Arc
During the Fourth Shinobi World War, Darui is placed in charge of the First Division of the Allied Shinobi Forces. He and his platoon mobilised alongside the others but soon break off and heads for the coast of the Land of Lightning to defend against an approaching portion of the Akatsuki forces. Before the opposing army makes landfall, Darui launches the first attack, using his Lightning Release: Black Panther technique to electrocute dozens of White Zetsu Army clones as they marched through the sea towards land. As the battle rages, Darui confronts the revived Gold and Silver Brothers where he apologises to them for needing to defeat them and tarnish their reputations even further. As the battle ensues he is joined by Samui and Atsui as the two brothers reveal their weapons of choice: the Treasured Tools of the Sage of the Six Paths. As they battle the brothers, a few Zetsu clones try to ambush them but they are saved by Atsui's attack. He tries to stop Atsui before he rushes off to face Kinkaku and Ginkaku but watches on as both Atsui and Samui are hit with the Kōkinjō and have their severed. He watches in shock as Atsui is sucked into the Benihisago and Samui is taken hostage. As Darui apologises to Samui for what he was about to do, he severs Kinkaku's arm and uses his Storm Release: Laser Circus attack hitting both Kinkaku and Ginkaku who are shocked to see that the missiles from the attack were guided. This assault ends somewhat in defeat as Samui is absorbed into the Benihisago and Darui is hit with the Kōkinjō and his word soul severed with the Shichiseiken.

Having learned how the tools work by watching what happened to Atsui and Samui, Darui knows he can avoid being caught in the Benihisago by not saying his most-said word:. However, he inadvertently utters the word by saying, "". As he is sucked in, he says three times, making that his most-said word and thus stopping the suction. After his escape, Darui uses his sword and is able to knock Ginkaku into the Kōkinjō and commandeer the Shichiseiken and the Benihisago. After looking at his changed most said word, he realises that he was very apologetic by nature and says that he'll accept that. He then launches a new tactic and distracts Kinkaku by throwing his sword at him and then follows up with his Laser Circus technique again which buffets Kinkaku, giving him a chance to sever Ginkaku's word soul with the Shichiseiken.

Ginkaku then says his most used word,, and gets sealed inside the Benihisago. As he begins to suffer from the massive chakra drain of the Treasured Tools, Darui witnesses Kinkaku turn into his six-tailed form and rampage through the battlefield. To stop Kinkaku, headquarters sends him the Kohaku no Jōhei and Team 10 to provide support for him. While Shikamaru and Chōji distract Kinkaku, Ino uses her Mind Body Switch Technique to take possession of Kinkaku's body.

Darui then calls out to Kinkaku and Ino forces Kinkaku to respond, activating the Kohaku no Jōhei and sucking Kinkaku in.

As Kinkaku is sealed he wonders how he and his sibling could've been defeated by "copper" pieces, and Darui tells him that when you have a bunch of copper coins, they can be worth just as much as a gold coin. With the Kōkinjō getting sealed along with Kinkaku, Darui has no way to use the Benihisago. He nevertheless hangs onto it, hoping to find a way to free Samui and Atsui. In the meantime, he helps subdue the revived Kakuzu. By nightfall Kakuzu and the rest of Akatsuki's forces have been dealt with. Before they can claim victory, Tobi appears on the battlefield with the Demonic Statue of the Outer Path. While the statue wreaks havoc, Tobi confronts Darui and tries to take the Benihisago and the Kohaku no Jōhei. Fearing Tobi's intentions, Darui and Shikamaru try to stop him, only to be attacked by the statue. They are saved by Chōji and Kitsuchi respectively while Tobi escapes with the tools. With this, they start retreating as night begins to fall.

The next morning, Darui and the other shinobi are made to stand apart inside circles until Naruto can arrive on the battlefield and weed out the impostor shinobi. Darui later expresses his disbelief that the Raikage had actually agreed to let the jinchūriki out of confinement.

Trivia

 * Darui is Japanese for "sluggish", "dull", referring to his lazy, languid way of speaking.
 * A running gag with Darui is that every time A destroys a wall when leaving a room, Darui apologises for A and tries to use the door while C thinks they should just use the hole in the wall too.

Quotes

 * (To the Gold and Silver Brothers) "It kills me to do this to such great men. Some of that Silver and Gold plating may start to flake off a little when my Storm Release hits you! Even if it's a little dull!"
 * (To Ginkaku)
 * (To Kinkaku) "It's true that words can be used as tools, to lie and deceive. But when it really counts… (pointing to heart)— they're also the only way to tell the truth about how you feel right here."
 * (To Kinkaku upon defeating him.) "Silver and gold may shine more brightly than copper, and are more valuable because of it. But if you gather enough copper together, it's worth just as much as that one gold coin. You acted like you were solid gold, but I guess it was all a front… that's why we won! Sorry we had to strip off that gold plating."
