Alright /a/, this has been bothering me for a while. Haruka's obviously gonna win. For one, revolvers NEVER misfire. Should the one in a trillion or whatever chance that a misfire DOES happen, it'll be on Mitsuki's end. Also, Haruka's pointing her gun at the perfect spot, the bullet will catch Mitsuki in the frontal lobe meaning instant death. Where's Mitsuki pointing her gun? The neck? The jaw? It's hard to tell, but either way Haruka stands a chance at survival, even if it's very slim, unlike Mitsuki.
