(This is the same voice as Igor so scroll down and feel free to try for both characters!)

description:
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 and unfunny jokes 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 SEES.

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; he is far from the chairman SEES knew, something Aigis comments on if asked by the player a little after the event. He then becomes hostile, attempting to kill the ones who relied on him and thought of him as a trustworthy figure.
