Shukketsu Manipulation Technique

The Shukketsu Manipulation Technique is a technique that has been passed down in the Shukketsu Clan for generations. Only members of the Shukketsu Clan know of its secrets and ability to perform it. However, only those born within the Shukketsu Clan is capable of using the ability, as the DNA is also a factor that allows the user to use this technique. It was founded by the original Shukketsu Clan member, Shukketsu Utu.

Overview
The Shukketsu Manipulation Technique requires two things of the user. For one, to have been born into the Shukketsu Clan, meaning, the user must be a descendant of Shukketsu Utu. Secondly, the actual usage of the technique requires for the user to implement their own blood type and the opponent's blood type. The blood type of the user must be able to "donate" into the victim's body correctly. '''An example of this being how in real life, when a patient is in need of blood, only certain blood types are capable of being accepted into the body. So, let's use Blood Type AB+ as an example of this. AB+ recipients may receive blood from everyone, however, they are only able to donate blood to AB+, meaning that a user of this technique that is AB+ may only use their technique on an AB+ person.'''

Each member of the clan has a specific technique that has already been decided for them. Since each human has a Blood Type, they are born with that specific technique. Users of this Fighting Style cannot alter the technique that has been decided for them. The reason for this is, when Shukketsu Utu created this technique, he bred until he had 7 different children with different Blood Types and taught them this technique. It was then that those 7 children found out their Blood Types unique technique. Ever since this technique was created, the technique within a Blood Type has been set in stone, and was fated to be passed along for all eternity.

There have been cases, however, when a user isn't only subjected to a singular technique. An example of this is III, as he is capable of creating bodies from scratch by taking the blood out from his own body and forming them into bones, organs, flesh, etc., however, of course, this takes a great toll on III. Another example of this is Hepen, as he is able to accelerate the speed of cells within a person regardless, including white blood cells. There is a limit however, as Hepen needs to have contact with the person to do this, and they must be lacking in a specific type of cell.

This technique also has a passive ability that in turn, harms the user depending on their own blood type and the opponent's.
