This is a basic technique that is taught by Kagegakure's Ninja Academy. The user gathers a sphere of white chakra in their hand, which will then levitate and follow the user at a set distance and elevation. The light which the sphere gives off is used for illuminating dark areas, such as caves. Miyuki Murakami developed this technique further, to create a combat variation of it that can temporarily blind her opponents.
This technique is based off of the Hidden Move Flash from the Pokemon series.
