So basically the plot is about an evil group of Pokemon trying to annihilate humans from the earth, and a group of 'good trained' pokemon, who believe that humans and pokemon should live and cooperate together like friends, group together to counter these. The evil faction gets an inkling of this, and thus traps all of them on a supposedly lone island, to obliterate them one by one from their existence. The good pokemon, howewer, decide to hold a discussion every day at afternoon, and decide whom they want to lynch, for they don't exactly know who among them is the evil soul. Many of them also have powerful and not-so-powerful roles that they can use every night to assist the town on the next day. So, it is up to the town aka good pokemon to save the humans from annihilation and eliminating these mafia aka evil pokemon from earth.
With that, I announce the commencement of day one, with 20 alive it takes 11 for a majority lynch.
