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 uses it on Ichigo Kurosaki with the incantation, it is 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 multiply and appear to enclose themselves on their victim. Aizen claims, at least with the incantation, that it has the power to distort space and time.
