Hajime Sugoroku

Hajime is stern, irritable, ill-tempered, uptight and intimidating in nature. He takes his duties very seriously and is immensely dedicated to his job; he is said to have reached his current levels of strength through pure hard work and commitment, which has gained significant admiration and notoriety from his subordinates.[10] He claims that he is willing to do anything for the sake of his job, including maiming and killing others if necessary; this mindset allows him to attempt to do so with no signs of remorse or empathy,[11] causing him to be recognized as a needlessly violent and aggressive person. Despite this, he is often selfish and complains if he is forced to do extra work.[12] He is noted to be a workaholic and becomes irrationally bored when forced to take even short amounts of time off;[13] when he receives a three-day suspension due to his own violent actions, he resorts to completing paperwork outside his own department[14] and performing volunteer work[15] to reduce his boredom.

Despite his habitual dedication and efficiency, Hajime has proven to be rather air-headed and forgetful when it comes to matters outside of his duties.[16] In addition, he is not above breaking rules himself, such as keeping a pet cat at work,[17] habitually smoking in non-smoking areas with no concern for the protests of others Hajime is a short-tempered individual who is prone to both yelling at and acting violently[20] towards those who anger him, believing that in doing so others will eventually learn their place;[21] he tends to advise brute force as the most effective way to deal with troublesome prisoners[22][23] and has to be held back by his coworkers on multiple occasions.[24][25] His aggravation increases in times of stress, which occurs regularly due to the antics of cell thirteen and the thought of being punished as a result; as well as being more irritable during such times, he tends to experience chronic stomach pains.[26]

Hajime is an apathetic, arrogant and remorseless individual who admits to these traits openly, but does little to rectify them. He routinely admits that he acts only for his own sake and, during a deadly battle with Enki Gokuu, stops to complain about his personal problems and setbacks that occurred as a result.[27] He rarely considers how a given situation will impact those other than him, and his obnoxious attitude contributes greatly to the tense relationship that he and his coworkers share; he often speaks condescendingly to them,[28] seeming to see himself as superior to them because of his status as the prison’s strongest guard. Despite this, he doesn’t appear to hold this title in very high regard.[29] He cares very little for the opinions of others and rarely boasts about his superior abilities, further indicating his apathy.

You were acting up again. So he is going to teach you to mind the only way he knows how
