Strength of a Hundred Seal

The Strength of a Hundred Seal (百豪の印­, Byakugō no In ) is a sealing technique that requires extremely delicate chakra control to complete that dates to the era of the Sage of the Six Paths . Maintaining a very precise control for several years, the user concentrates their chakra in the same area, usually on the forehead, and creates a permanent rhomboid-shaped seal that stores all the energy accumulated during that period. Once completed, the user does not have to redirect chakra to complete the seal, making use of their own chakra freely and without waste .

When the seal is released, the accumulated chakra is released through the user's body, and the abilities in both ninjutsu and taijutsu are greatly amplified . Once the seal is closed, the rhomboid mark remains on the forehead. It is also possible to share the chakra inside the seal with another person with physical contact. Sakura Haruno lent Obito Uchiha part of her chakra to power up his Kamui .

The user has the ability to use two techniques only possible thanks to the seal: the ability to summon Katsuyu, which is symbiotically connected to the user through the seal and whose abilities depend on the amount of chakra it has inside; and Creation Rebirth, a regeneration technique possible thanks to the amount of chakra stored in the seal.

The only bearers of the Strength of a Hundred Seal are Tsunade and her apprentice, Sakura Haruno .
