The Simon Rings are special Rings belonging to the Simon Famiglia and are said to be powerful enough to rival the Original Vongola Rings' power. The Flames produced by the Simon Rings are different from the other Rings, as they are called the Dying Will Flames of the Earth. The Simon Rings were discovered buried in Cozarto Simon's grave after the earthquake that transported Tsuna's Family into the present, wrapped in small cloths that contain the Vongola Symbol crossed out with "delitto" (Sin) written on it.
