Ōkasen

is a Kidō spell.

Description
Ōkasen is primarily used for offense. The practitioner raises his/her Zanpakutō horizontally in front of him/her and generates a yellow orb that widens itself along the length of their sword. Once it is fully charged it fires outward as a horizontal blast, in a wide arc of yellow energy at the target. It is one of the mid-level Hadō spells.
