Giotto (Katekyo Hitman Reborn!)

Giotto, later voluntarily renamed Ieyasu Sawada, is the founder and first boss of the Vongola Famiglia, giving him the title of Vongola Primo. He is the progenitor of the Blood of Vongola, and the direct ancestor of Iemitsu Sawada and Tsunayoshi Sawada. He is also the creator of the Zero Point Breakthrough. Giotto's will and spirit currently resides in the Sky Vongola Ring, in the same way as the souls of the other seven Vongola Bosses who have already passed away.
