Kurohitsugi

Description
Kurohitsugi is primarily used for offense. The practitioner generates a purple-black spiritual energy that envelops the target with a powerful torrent of gravity that takes the form of a box of black energy, covered in several spear-like protrusions. The spears then pierce the box, lacerating the one inside from head to toe. The spell is very difficult to use, as even Aizen could only unleash a third of its power without stating the particular incantation, when he used it on Sajin Komamura.

However, when Aizen later used it on Ichigo Kurosaki with the incantation, he stated that it possessed enough power to distort space and time. It is also noticeably different in appearance. The sky appears to darken as multiple boxes of black energy appear, each of them topped off with cross-shaped spears, before they appear to enclose themselves on their victim.

Incantation
"Seeping crest of turbidity, arrogant vessel of lunacy. Boil forth and deny, grow numb and flicker, disrupting sleep. Crawling queen of iron, eternally self-destructing doll of mud. Unite, repulse. Fill with soil and know your own powerlessness."
