Dazai always hides his true intentions, he's always confident in his plans and is usually right. Using his cold exterior to hide the darker parts of his mind, Dazai's blood and heart is as dark as (if not darker than) the mafia itself. His personality and thoughts are far too complex for anyone less smart than he is to grasp; it's as if he doesn't know what persona to put on, the confident and fun act or the distant and emotionless one.
