Apperrance:is the former Boss of the Gesso Famiglia, and the former incumbent Leader of the Millefiore Famiglia due to the fact that he's imprisoned. His aim was to obtain the "Ultimate Power" (Tri-ni-set), by gathering the Vongola Rings, Mare Rings, and Arcobaleno Pacifiers together in one place; he has a portrait that has a slot for each item. To achieve his goals, Byakuran has ordered the complete extermination of the Vongola Family, even targeting their friends and allies. He also had a special radiation released into the atmosphere in order to kill all Arcobaleno members. Before the appearances of young Tsuna and his friends in the Future, Byakuran had been researching them, as well as time travel, in order to get a hold of the Vongola Rings, which had been destroyed in his time. Though he used to possess the Sky Mare Ring, he has purposefully hidden his true abilities, and maintains a carefree attitude, even during his fight with Mukuro Rokudo, whom he critically injured. Despite his ruthlessness toward his enemies, he has a cheerful disposition when around his subordinates, especially toward Shoichi Irie; however, this is only if they hold his interest. Once he "gets bored" of someone, he won't hesitate to have them killed.
