This technique turns the moisture particles in the air into an ice disk. They can be hurled with tremendous force at a target and are hard to dodge because of their transparency. The disks can be used defensively, creating highly durable shields or disks to stand on for hovering in the air. They can also be strung together to spy on areas. By forming the ice into a large lens, the user can hover in the sky to focus the rays of the sun into a powerful beam capable of melting and exploding the pinpointed area, but when used in this manner, the beam can be reflected onto the user or anyone else, using a reflective surface, as demonstrated by Naruto who reflected the beams created by Renga's technique on Renga himself using his Konoha forehead protector.
