A Purifichi I Dei (Purify the Gods in Italian) is a Fantasma Bianca zanpakuto. Like Shinigami Zanpakuto, it has three forms. The first form is Apòstolo, followed by Piena Fusione.
(Italian for Apostle) A sort of Shikai, but it usually covers the entire landscape around the user.
(Italian for Full Fusion) A sort of Bankai, but it really doesn't change from the Apòstolo, except that it focuses the whole landscape created by it into a single weapon. This weapon has no more overall power, but when you attack with it, it focuses EVERYTHING from the Apòstolo's landscape into the attack, not only one part.
