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" (だるい, 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.[5] 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" (すみません, sumimasen) just as much as the word "dull". He also possesses a strong loyalty to the Fourth Raikage whom he often addresses as "boss" (ボス, bosu), rather than adding the suffix "sama" to his title as others do. The Fourth in turn, considers Darui his "second right hand",[3] 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.[6] 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.
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 (水) and lightning (雷) 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.[7] 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.
Darui is a highly skilled and capable shinobi evidenced by his position as leader of the First Division of the Allied Shinobi Forces. He has shown considerable speed, having been able to coordinate a combined assault on Taka alongside the lightning enhanced Fourth Raikage, as well as protect C from being blindsided from behind by Suigetsu Hōzuki.[8] 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. 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.[3] After the war, his skills and power increased to the point where he achieved the rank of Fifth Raikage, succeeding A.[2]
His chakra reserves are extensive enough to not die of chakra exhaustion after using three of the Treasured Tools of the Sage of the Six Paths and still have enough chakra remaining to continue fighting.
Darui is proficient with wind,[1] 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, making his lightning-based techniques even more powerful.[4] 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.[10] In the anime, he could even increase the power and effectiveness of the technique using a shadow clone.[11]
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.[12]
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,[13] and knock Ginkaku into Kinkaku's Kōkinjō while quickly seizing the Shichiseiken and Benihisago.
"Darui" (怠い) is Japanese for "sluggish" or "dull", referring to his lazy, languid way of speaking.
