Because Ekko and you are about to ruin the game (IF you both are town in the first place which I'm not convinced of). It's not sus, it's called common sense. Something that both of you seem to be missing.
I'm townreading Kiku too, so I think this would be another bad shot either way.
You probably think that we would be scared now that you threatened to shoot Fuji, Kiku or me and that we would start to take our votes off from you beause of that, don't you? And that's exactly why I think we shouldn't and why I'm voting you now. I don't fear to get shot and I certainly don't fear you!
