This technique releases the seal on the Fury technique and then gathers natural energy from the earth and atmosphere to be used for the jutsu. The bearer of the seal acts as a passive vessel for the natural energy, which makes it possible to use Fury without their cooperation.
Trivia
This jutsu is similar to senjutsu in that it also gathers natural energy. However, unlike Sage Mode, the chakra does not directly power the user's abilities.
