Rank: B(due to the flowers needs to be set up)
Type: ninjutsu
Style: ninja art
Description: This technique is solely used by Guren, First she creates a number of crystal flowers. Then she grows these flowers into a gigantic labyrinth consisting of red crystals, confusing all enemies inside of it. The enemies will mostly be lost because of the fact that the red crystals reflect their personal image as well as generates mirror images of the routes, paths, and details within the labyrinth, confusing and intimidating them. It is even capable of confusing the Byakugan.
Because of the crystal's stable molecular structure, a simple attack focused at one point is rendered useless, as its wide surface will evenly disperse the force of the attack, reducing the attack's effectiveness. To overcome this technique, an attack that has impact force both wide and powerful is required to smash through it.
