Ikutsuki's true personality is somewhat difficult to pinpoint as he exhibits a sharp shift after one point in the story. It can be argued that either one of his personalities were the real one, while the other was a manifestation simply to further his goals or a distortion based on the circumstances. While he is acting as the adviser of SEES, he is quite polite and sophisticated, never needing to change his tone or manner. He is friendly, always accompanied with a gentle smile and a set of bad puns to provide comedy relief when it is needed, and perhaps not needed. It is implied the chairman knows more than he lets on but nonetheless he is the main source of knowledge for the group regarding all things related to the Dark Hour and thus acts as guidance for the main cast. After the defeat of the twelve Shadows, Ikutsuki shows a very different side of him to the party at the entrance of Tartarus. Manipulative, his dialogue speckled with evidence of his twisted savior complex, and his lack of remorse for what he's done; a grin befitting an insane man confirms that he is far from the chairman the cast has known.
