Kuro Higi

The Kuro Higi (黒秘技, Secret Black Technique) is a Hollow dissimulation device created to quickly get rid of an attacking Hollow. Not meant for offense, the Kuro Higi must be planted before hand and when triggered releases a large demon-like container that locks the Hollow with in. From within, a powerful poisonous gas is secreted that breaks down spiritual particles on contact.
