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.
Giotto is a young man of average height with spiky blond hair and sharp orange eyes. He looks similar to Tsuna. He wears a black pinstripe suit, white undershirt, and black tie. His cloak is black with an upturned collar, red tassels, and cloak clasps with intricate designs. He also wears his I-Gloves. In most of his appearances, he is constantly in Hyper Dying Will Mode.
Giotto is a calm and collected leader with a strong sense of justice. He actively pursues what he believes is right for the people of his hometown. Despite Vongola rising to power more than it originally was, Giotto never let the power to get into his head, always prioritizing the safety of the weak people over ruling them, staying true to his conviction to the very end.
Giotto deeply cares for his friends and Famiglia and is willing to protect them from harm. He is very charismatic, able to attract and welcome many kinds of people into his vigilante group. In addition to his charisma, Reborn once stated that Vongola Primo was the kind of person who accepted anyone into the Famiglia, regardless of background. He values friendship and other bonds that he has with people he knows, and wishes for their bonds to be always remembered.
He is also a forgiving person that never holds any grudges. After Demon Spade betrayed him, Giotto still considered him as one of his Guardians and continued to believe with the bond they shared together.
Tsuna was noted to be similar to Giotto in many aspects, especially his soft nature. He also shares Tsuna's belief that a person who is not willing to die protecting his friends, does not deserve to be a Vongola boss.
