Fire Release: Containment Cell

After forming the needed hand signals, the user blasts a gigantic ball of fire towards their target, then uses wind chakra to make the fireball settle around them and trap them in a dome of intense flames that turn all around the user, even in the air.

These flames are ideal for torturing or interrogating the person. Using their wind chakra, the user can have the flames feed on the air inside the dome, sapping away any oxygen for the target. If the target does not comply to anything the user asks, the user can have the fire completely eat the oxygen and cause the target to eventually suffocate. With the wind chakra, the user can detonate the sphere, causing a large explosion at any time.
