Kurohitsugi

is a Kidō spell.

Description
Kurohitsugi is a high-level Kidō which seals its target in a black spiritual coffin. The practitioner generates a purple/black spiritual energy which, enveloping the target with a powerful torrent of gravity, takes the form of a box of black energy, covered in several spear-like protrusions. The spears, piercing the box, lacerate 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 chanting the particular incantation when he used it on Sajin Komamura.

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 enclose themselves on their victim. Aizen claims that, at least with the incantation, it has the power to distort space and time.

Incantation

The eternally self-destructing doll of mud.  Unite!  Repulse!  Fill the earth, and know your own powerlessness!" Kanji= 滲み出す混濁の紋章. 不遜なる狂気の器! 湧き上がり否定し! 痺れ瞬き! 眠りを妨げる! 爬行する鉄の王女! 絶えず自壊する泥の人形! 結合せよ! 反発せよ! 地に満ち己の無力を知れ! Romanji= Nijimidasu kondaku no monshō. Fusonnaru kyōki no utsuwa! Wakiagari hiteishi!
