As the name implies, Blood Manipulation is a Cursed Technique that allows the user to control and shape their blood beyond its natural form or motion for a variety of effects. It can be used to manipulate every aspect of the user's blood, including blood composition, plasma, and red blood cells. Internal and external blood can be utilized as long as it belongs to the user.
Blood can be manipulated in a variety of ways utilizing this technique. External blood can be hardened or shaped to create mid-range projectiles. Internal blood can be used to control one's own pulse rate and body temperature, effectively giving themselves more energy to increase their physical capabilities.
As with any Cursed Technique, Blood Manipulation's efficiency and strength depend on the user. Noritoshi's Piercing Blood was unable to harm Hanami while Choso's was able to severely injure Yuji. External blood can also be nullified under specific circumstances where the amount of water in the area renders blood unable to hold any shape.
The user is also limited by the amount of their own blood they have access too. Too much blood loss could obviously result in death, so user's generally prepare blood bags or weapons dipped in their blood in advance.
