The Shirono Family Massacre (白野 家族 殺戮, Whitefield Family Massacre), also called Shiki's Vendetta, was an event that occurred shortly following the initial formation of the Ryū Order and Horiwari. Shiki Shirono, angered at the mistreatment he suffered at his own families hands, began plotting their downfall. His plans were sped up by his meeting with Gengetsu - one of the many Reikon Kyuuban hiding out in the Human World.
