The Vongola Sin is kept and protected by the current Vongola Boss. Its special box has the Vongola crest, and four pearls at its corners, similar to the vial holding the Penalty. The Vongola Sin contains the blood of Simon Cozzato, Simon Primo. It was created by the Giotto to leave behind memories after of his battles. People outside of the Vongola Famiglia can only see it during the Inheritance Ceremony.
Plot overview Edit
The Simon Famiglia managed to steal the Vongola Sin. By dripping it onto his ring, Enma was able to go into Hyper Dying Will Mode. It was then revealed that the Sin was the only reason why the Simon went to the Ceremony and also was the blood of Simon Cozzato.
