Basically, we have no suspicion on anyone. Day 1 lynchings are completely random in hopes of randomly catching Mafia. We have 16 players in game, so let's assume there are 3 or 4 Mafia (closer to three). That's, at most, a 1/5 chance at hitting Mafia, or about 20%. You include power roles, and we have to be extra careful. Best bet would be to have everyone post one person whom they think is worth lynching, not just FOS, but a person they honestly think won't be missed. From there, you, Zero, have to pick. That is the easiest way to do this.
Also, we can use this to see who will be in active. Kawaii, post something. If you cannot, you deserve to die.
So my vote goes to Kawaii Bunny for now.
