Shiketsumyaku

is a kekkei mōra which gives the user to manipulate their blood cells. By infusing their stem cells with chakra, the user can create any kind of blood cell in copious amounts and to their liking. It is said to be the sister ability of Shikotsumyaku and originates within the same clan as the aforementioned ability. Shiketsumyaku first manifested within Tenmu Ōtsutsuki who then passed it on to his followers. As such, it is seemingly just as rare as its sister ability.

Like Shikotsumyaku, it also seems to grant the user a unique body which is capable of handling an increased amount of blood. It also grants them the ability to survive with an extremely low volume of blood, which is usually fatal to other living beings. Because of this, Tenmu states that a user with sufficient chakra is incapable of dying from blood loss. One of the features of this unique body is elongated canines.

Abilities
Shiketsumyaku is primarily used to increase the amount of blood in the user's body, allowing for it to be used in the performance of special abilities.

Obtaining Shiketsumyaku
Shiketsumyaku is a unique bloodline trait in that it can only be passed on when a user of this ability bites the prospective target — passing on their blood in the process. However, this process has a drawback. Each time the ability is passed on, it becomes weaker until it is eventually completely ineffective. This means only Tenmu and his direct followers (whom he shared this power with) can use it to the fullest potential.
