Nisshō Kurosaki

Zanpakutō
Kōsenga (黄泉牙, Underworld Fang; literally meaning "Land of the Dead's Teeth"): It has a blue handle and a star shaped tsuba which has been hollowed out. It is not worn on his person and summoned via a special seal on his forearm. It blade is unique in that the cutting edge is found on the reverse side, making it a rare sakabatō and stranger still that it cannot cut while in its sealed form. ====Shikai==== The release command is Tear (鉤裂き, "kagizaki"; "Rip" in the Viz Dub). Kōsenga resonates and releases a wave of spiritual energy which engulfs the blade. Once the energy stops flaring outwards, Kōsenga starts to glow violet as it changes from a sakabato into a Nodachi, retaining some of its sealed form characteristics, however the major change is seen in the blade itself, which has six fin-like protrusions jutting from the back of the blade, getting larger as it nears the hilt. The crossguard of this new blade is filled in and colored gold and the hilt is seen to have become royal blue.
