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.
