The initial problem I see with roleclaiming in this particular game is that no one one knows what the roles are, so the mafia can make up whatever they want. However, as long as we have Alex around (and we've done a nice job protecting him so far) we can check claims that may sound off, so now could be a good time to do it.
Since I have yet to attack today and am not sure if I'll get a chance to get back on here before the end of the phase, [Attack] Hibikaze. Sorry if you turn out innocent, which seems more likely now that Abby flipped mafia.
Also, Kaneki, not sure why you said "placeholder", there are no placeholder attacks, once you attack that's it, since damage is done in real time.
