He's the least aggressive member of the delinquents.[10] Additionally, in a spectrum from most rational to most emotional, among the delinquents, Dairoku is the second most rational.[11] Not only that, but Dairoku is also the most introverted delinquent.[12] Due to Dairoku being a naturally very quiet guy, he can sometimes give off the false impression that he's being judgemental or that he is hiding something. But, it's not true, Dairoku is just a quiet person.[13] YandereDev believes that Dairoku has a negative view of women in general because the people who bullied him into considering suicide were girls. When Dairoku sees a girl, he thinks of all of the negative experiences that the bullies gave him, and thinks, "I bet this girl's the same." He assumes that all girls have the same negative traits of the girls who bullied him. YandereDev has stated that in order for Dairoku to fall in love with a girl, that girl would have to not behave similarly to the girls who bullied him.
