The Kimza Weapon: Great Dragon Summoning is one of the fifteen Kimza Weapons and is considered the most powerful of them all. This technique is considered an S-rank technique that only a kage-leveled shinobi should know. It is also known by the highest elder in the village council. It is called the "Dragon of Double Death" due to its effects. Sanhiro eventually does not need to use this technique, as he creates a more powerful and larger version of it. This version is considered his most powerful ninjutsu technique.
