Darui

is a shinobi of Kumogakure and the right-hand-man of the Fourth Raikage, whom he later succeeds as the.

Background
Darui was once a student of the Third Raikage. During his training, Darui learned, among other things, the Raikage's unique black lightning technique.

In the anime, when Konohagakure and Sunagakure invited other villages to an unscheduled joint Chūnin Exams, the Fourth Raikage was furious at this, taking it as an underhanded scheme to attack Kumogakure. While A flatly told his men to reject Tsunade's offer, Darui informed A that he already informed Killer B of this. A quickly instructed Darui and C to prevent B, who was already on his way to leave for the exams, from attending.

Personality
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 — 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 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. Because of this trust, Darui was put in charge of the First Division as well. Darui is also quite understanding. When Naruto was late to the five Kage meeting, he quickly defended Naruto by saying the life of a Kage as well as a father and husband is a busy one. Despite this, Darui still seems to retain his laid back attitude as he sat in a casual and laid back manner during the Kage meeting.

Appearance
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 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.

Years after the Fourth Shinobi World War and becoming Raikage, Darui grew a small moustache and gained creases at the corner of his mouth. While his attire was mostly unchanged, he began wearing a hood in place of the high-collar he wore before.

Abilities
Darui is a highly skilled and capable shinobi, evidenced by his position as the leader of the First Division of the Allied Shinobi Forces. He could also battle and defeat Suigetsu Hōzuki, a powerful member of Taka. His skills 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. This was witnessed by him defeating the Gold and Silver Brothers nearly single-handedly, as well as uncovering the mechanisms of the Treasured Tools during his battle with the brothers. Years after the war, Darui's skills and power increased greatly to the point where he achieved the rank of Fifth Raikage, succeeding A.

Nature Transformation
Darui is proficient with wind, water, and lightning techniques, and is able to use two separate nature techniques simultaneously. He is crafty and quick-thinking in his combos, such as using water technique to pin the enemy down followed by lightning to make the effect deadlier. He is also able to combine his water and lightning-natures to create the 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, making his lightning-based techniques even more powerful. With the power of the black lightning, he can use techniques such as the Lightning Release: Black Panther to immobilise or kill several enemies. According to one of his comrades, he is the only person to have inherited the Third Raikage's technique. In the anime, he could even increase the power and effectiveness of the technique using a shadow clone.

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.

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 could clash with Suigetsu'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.

Physical and Chakra Prowess
Darui has shown impressive speed, being able to coordinate a combined assault on Taka alongside the lightning enhanced Fourth Raikage, as well as protect C from being attacked from behind by Suigetsu. He also possesses considerable chakra reserves and stamina, as he did not die of exhaustion after using three of the Treasured Tools of the Sage of the Six Paths and still had enough chakra to continue fighting effectively.

Five Kage Summit
Darui and C were chosen to escort the Fourth Raikage to the Kage Summit in the Land of Iron. Shortly after they had 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, standing between the Raikage and the other Kage's bodyguards whom had interpreted this as an aggressive action towards their own respective leaders. Signalled to stand down, they each returned to their posts and things settled down, only to again come to the Raikage's side when White Zetsu appeared later during the meeting. White Zetsu revealed that Sasuke Uchiha, Killer B's captor, was nearby, so Darui and C accompanied the Raikage to track Sasuke down. When the Raikage broke down a wall to leave, Darui emphatically apologised for both it and the table before departing.

When they located Sasuke and his team, Suigetsu immediately charged at C when the battle got underway. 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 looked upon the Raikage as he grew increasingly enraged and reckless during his fight with Sasuke. The Sunagakure delegation soon arrived to provide assistance, and Darui joined forces with them while C healed the Raikage, and bombarded Sasuke with a devastating attack. Using Susanoo, Sasuke survived their assault and destroyed the pillars that supported the building, causing the roof to collapse in on them; Darui was protected from the falling debris by the Fifth Kazekage's sand. With Sasuke's escape and everyone unharmed, Darui and C returned to the Summit hall, where Tobi explained his Eye of the Moon Plan to them. As part of his explanation he revealed that B only pretended to be captured, leading Darui to state that this revelation did not surprise him at all.

After the formation of the Allied Shinobi Forces, Darui joined 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 requested a full debriefing of what had happened since they left. Darui later attended a war council meeting convened by the Raikage.

Fourth Shinobi World War: Confrontation
During the Fourth Shinobi World War, Darui was 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 headed for the coast of the Land of Lightning to defend against an approaching portion of the Akatsuki forces. Before the opposing army made landfall, Darui launched 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. Darui confronted the reincarnated Gold and Silver Brothers where he apologised to them for needing to defeat them and tarnish their reputations even further.

As the battle ensued, he is joined by Samui and Atsui as the two brothers revealed their weapons of choice: the Treasured Tools of the Sage of the Six Paths. During the battle, few White Zetsu clones tried to ambush them, but they are easily defeated by Atsui's attack. Darui tried to stop Atsui before he rushed off to face Kinkaku and Ginkaku and looked on as both Atsui and Samui were hit with the Kōkinjō and had their severed later horrified when Atsui was sucked into the Benihisago and Samui is taken hostage. Apologising to Samui for what he was about to do, he severed Kinkaku's arm and used 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 ended somewhat in defeat as Samui is absorbed into the Benihisago and Darui was hit with the Kōkinjō and his word soul severed with the Shichiseiken.

Having gained a good idea of how the tools worked by watching what happened to Atsui and Samui, Darui knew he could avoid being caught in the Benihisago by not saying his most-said word:. However, he inadvertently uttered the word when he admonished the brothers and stated, "". As he is sucked in, he started apologising to every-one saying three times, making that his most-said word and thus stopping the suction. After his escaped, Darui launched an attack immediately with his sword and was able to knock Ginkaku into the Kōkinjō and commandeered both the Shichiseiken and the Benihisago. After looking at his changed most-said word, he realised that he was very apologetic by nature and stated that he'd accept that. He then launched a new tactic and distracted Kinkaku by throwing his sword at him and then followed up with his Laser Circus technique again which buffeted Kinkaku, giving him a chance to sever Ginkaku's word soul with the Shichiseiken.

Ginkaku then said his most used word, in pleading for his brother to help him, and got sealed inside the Benihisago. As he began to suffer from the massive chakra drain of the Treasured Tools, Darui witnessed Kinkaku turn into his six-tailed, Version 2 form and rampaged on the battlefield. To stop Kinkaku, headquarters sent Darui the Kohaku no Jōhei and Team 10 to provide support for him. While Shikamaru and Chōji distracted Kinkaku, Ino used her Mind Body Switch Technique to take possession of Kinkaku's body.

Darui then called out to Kinkaku and Ino forces Kinkaku to respond, activating the Kohaku no Jōhei and sucking Kinkaku in. As Kinkaku was sealed he wondered how he, and his sibling could've been defeated by "copper" pieces, and Darui responded stating that when you have a bunch of copper coins, together they can be worth just as much as a gold coin. With the Kōkinjō getting sealed along with Kinkaku, Darui had no way to use the Benihisago but nevertheless hung onto it, hoping to find a way to free Samui and Atsui. In the meantime, he helped subdue the reincarnated Kakuzu and by nightfall, Kakuzu and the rest of Akatsuki's forces had been dealt with. Before they could claim victory however, Tobi appeared on the battlefield with the Demonic Statue of the Outer Path. While the statue wreaked havoc, Tobi confronted Darui and tried to take the Benihisago and the Kohaku no Jōhei. Fearing Tobi's intentions, Darui and Shikamaru tried to stop him, only to be attacked by the statue. They are saved by Chōji and Kitsuchi respectively but this allowed Tobi to escape with the tools. With this, they start retreating as night began to fall.

The next morning, Darui and the other shinobi were made to stand apart inside circles until Naruto could arrive on the battlefield and weed out the impostor shinobi which had taken the form of their comrades during the night and was wreaking havoc and confusion on the allied shinobi. Darui later expressed his disbelief that the Raikage had actually agreed to let the jinchūriki out of confinement upon hearing that Naruto was headed to the battlefield.

Fourth Shinobi World War: Climax
Upon arriving on the battlefield where they were, Darui announced that the remainder of his division had arrived. With this, he and the other members of the Allied Shinobi Forces stood to face their opposition. Following the strategy relayed to them by Shikaku, Darui and C, along with several other Kumo-nin, begin the assault. With C and others amongst their ranks blinding the enemy with the Lightning Release: Lightning Illusion Flash of Lightning Pillar technique, Darui and several other Storm Release bearers, used the Storm Release: Laser Circus technique to aim for the beast's eye. Backed up by the medic-nin Sakura, Darui attempted to attack Obito Uchiha with a Storm Release attack but is quickly repulsed by the now fully-matured Ten-Tails who had escaped the hole which it had seemingly been trapped in.

Birth of the Ten-Tails' Jinchūriki
Darui later cautioned the other shinobi not to act rashly who wanted to go to the front to fight alongside the Hokage. This was seconded by Hashirama Senju who told them not to act carelessly. Darui would later assist the other shinobi battling Tobi. When tremors were felt around the battlefield, Darui informed everyone to brace for impact from the meteorite. He later fell victim to the Infinite Tsukuyomi along with the others.

Kaguya Ōtsutsuki Strikes
After Naruto was able to defeat and reform Sasuke, Darui along with everyone was released from the Infinite Tsukuyomi. After Tenten unsealed the Treasured Tool Benihisago from the scroll she sealed it in, she gave it to Darui who set a captured Atsui and Samui free from it.

Epilogue
Many years later, Darui succeeded A and became the Fifth Raikage. He, accompanied by Omoi, later attended the Five Kage Summit in Konohagakure. When the Tsuchikage and Mizukage commented on the Hokage's late arrival, Darui asked for them to forgive him as they were all very busy.

During one such meeting, Sasuke came forth to reveal evidence of a new White Zetsu Army being formed and a potential threat even greater than Kaguya. Ultimately, it was agreed to keep all this a secret from the public and to allow Sasuke to continue his research and investigate his sources further.

Creation and Conception
With Darui's design, Kishimoto noted that he wanted to immediately convey a sense of sluggishness. His collar is worn upturned for a sense of stylishness, and the two tattoos on his shoulders are there as challenges to his opponents, as well as to signify that he possesses a kekkei genkai.

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."
