That was actually how I was at first having the 5 die, and then getting shot later to make it look like Battler had killed them. But I couldn't fully figure out a way to fit Battler's death into that sequence, so I discarded it. Since from the beginning of my planning I had the thought. "Everyone but the victims are in the parlor at the time of Battler's death." To fortify it even more I was originally going to have Erika be in the story as well, and her eye witness that everyone was in the parlor would prove that. But since I got tired of writing, I cut Erika out of the story, expect the beginning mention, and I changed parlor to 'off Rokkenjima.'
