The Official Story
The official story of the Rokkenjima massacre states that, at the annual Ushiromiya family conference, an unknown perpetrator detonated an explosive that destroyed a large portion of the island and nearly everyone residing on it. It is believed that the motive behind the massacre was for the legendary stash of gold held by family head Kinzo Ushiromiya. The only known survivor of the explosion was Eva Ushiromiya. Several years after the massacre, two bottles containing messages written by Maria Ushiromiya were found. The messages detailed the exact events that transpired at the time of the massacre. However, both messages contradicted each other, detracting heavily from their authenticity. A piece of Maria Ushiromiya's jaw was later found as part of the official investigation. The case remains unsolved.
