"Fear is necessary for evolution. The fear that one could be destroyed at any moment. Thank you, Gin. Thanks to your efforts, I have finally risen to an existence that surpasses both Shinigami and Hollow."

The Arrogance of The Innocent: Xi has a ring, known as L'arroganza di Il Innocente, that he created. The ring allows him to access different elemental attributes, which he can infuse with his Reiryoku. This allows him to give an additional ability to the Kidō he conjures. It also seems to have spells of it's own, which he can use to aid him in combat. He is also able to use his knowledge of the item (being as he created it) to bypass the personality scan it does, to determine the attribute the user is allowed to use. This allows him to use all seven of the attributes, despite his personality being aligned toward darkness.
Spirale Dell'inferno - Disco (地獄のスパイラル - ディスク, Hell's Spiral - Disk): Using the L'arroganza di Il Innocente as a medium, Xi transfers his Reiryoku through it. This allows him to apply any attribute he wishes to the Reiryoku to increase the amount of damage it will do when the spell is fully conjured. The Reiryoku then takes the shape of three tomoe, which are tethered together by an energy link. The damage it can do is as strong, if not stronger, then a Getsuga Tenshō.
