Korose, Kamishini no Yari


 * is a Bankai technique used by Gin Ichimaru's Zanpakutō, Kamishini no Yari.

Definition
Kamishini no Yari's true ability as well as its deadliest aspect is not based on its length or speed but rather its ability to turn into dust for just a second when it expands out and contracts. There is a deadly poison inside the blade that dissolves and breaks down cells. He can leave a sliver of his Zanpakuto in an opponent when he retracts Kamishini no Yari, allowing him to kill an opponent at any time when he chooses to by uttering the technique name, while placing his hand up to the target. The result causes the target to completely break down and dissolve at the cellular level from the inside out.
