Burst is a direct is a direct application of Kuusou Gugenka. Since a user is capable of cycling their excess ki back into their body, it's also possible for them to produce more aura around themselves without having to worry about losing it. Burst infuses and accumulates ki energy into their weapon and body, momentarily injecting an arbitrary vector that allows for an exceptional boost of their abilities by instantaneously releasing the energy to reinforce them. It can be called a jet blast of ki energy to increase user’s movements in close combat, using the immense power of Kuusou Gugenka to executing large-scale body reinforcement increasing the user's physical strength and durability and provides a large pool of aura for any advanced techniques or individual skills they decide to use.
It would allow for even a stick to become a weapon of great power at her rank, but normal weapons will not be able to endure the energy-fueled attack and will be destroyed with one blow. User’s power increases with their available energy, i.e the bigger their reserves the more they can convert it into burst. Each of powerful blow contains enough energy that they are visible, and can be compared to a powerful shotgun. Simply striking the enemy's weapon causes the energy to penetrate it, and it fills the area with light.
