Shareholder

Shareholders are the intended listeners for each Kakos Industries broadcast. They are shareholders of the company, and the broadcasts made by Corin Deeth III are intended to update them on the status of Kakos's business endeavors, political movements, scientific studies, and various evil doings. Radios are sent to them before each broadcast, which the shareholders are required to destroy after the broadcast is finished.
Listening to a broadcast without being a shareholder is punishable by execution in some countries.
Shareholders are never allowed to meet in person, unless they are related. If they do meet, they must either get married, or die, a plot which Corin admits they stole from an anime. However, Corin also admits that this stipulation was technically only true at the precise moment he said it, intending to target two very specific shareholders who were meeting for the first time exactly when it was said. It was later announced that the stipulation has been rescinded, though all marriages already conducted would still be in effect.
