Akechi's character in the series as a whole will be extremely exaggerated. The plan is to have him be an obvious psychopath. He will say very obviously insanely violent things, but no one will catch on. Even though he has only one line in this first episode, he will be a recurring character. I would like auditions be limited to those willing to do his voice in later episodes, but this is basically a trial episode so don't let that dissuade you.
