To utilize his Fullbring, Giriko uses an antique gold pocket watch. When he uses Number Attack, green Reiatsu emanates from the pocket watch. As Giriko prepares to unleash the attack, the surface of the watch begins to glow brightly, and numbers are visibly released from the face. Giriko can control these green numbers and use them as projectiles to attack his opponent from a distance. Upon contact with a surface, the numbers cause small explosions.
