Kunikida is an incredibly organized and focused man, usually remaining calm and collected. He has almost everything in his life planned and dislikes sudden changes to that plan, everything down to his significant other is planned. Despite being strict Kunikida is very responsible and reliable, even willing to sacrifice himself for the safety of the innocent or for the agency. Dazai tends to piss him off as he takes advantage of Kunikida's nativity causing the poor man to have small outbursts.
