Haemoinkaiosis

Haemoinkaiosis, also known as Inky Blood Disorder or Writer's Blood, is an inherited genetic disorder that causes the blood to act as a powerful ink with supernatural properties. The ability allows the afflicted person to influence others when simple commands are written with executable intent. It is often found in people that have Haemophilia, but the disorders haven't been found to be caused by each other.

One of the leading researchers into Writer's Blood is Manjiro Masumoto, who sponsors and owns multiple clinics globally.
