Hand Seal

are used to perform many ninjutsu, genjutsu, and other secret arts other than taijutsu. The exact amount of chakra necessary to perform a jutsu is manipulated through hand seals. There are different sequences of hand seals for every technique, requiring memorization.

While techniques may require a number of hand seals to work, a skilled ninja can use less or even one to perform the same technique. An example of this is the Water Release: Water Dragon Bullet Technique, which requires a total of 44 hand seals to activate. Tobirama Senju, the Second Hokage, however, just needed to use one hand seal to complete the technique, a testament to his skill.

Although rare, it is possible for a shinobi to be able to do hand seals with just one hand. The only shinobi so far capable of this are Haku and Guren. im gay
