Earth Element: Light Rock Technique - a ninjutsu that reduces the target's gravity, making it significantly lighter. Applied to one's own body, the technique allows floating in the air and freely maneuvering, controlling flight with body movements. The user can also lighten other objects by touch, precisely adjusting the degree of weight loss. The price of lightness is the weakening of physical striking power - both one's own and that of those affected by the technique. Ōnoki, who mastered it perfectly, combined flight with other elements and could instantly switch to weight increase.
