Majutsu

refers to a line of techniques that predates the creation and classification of ninjutsu and incorporates the use and affinity for darkness and internal power covering a wide variety of abilities. It's practitioners were often pitted against their counterparts who practiced Kitoujutsu for both survival and the right to use their skills. Many forbidden ninjutsu techniques are derivations and rediscoveries of techniques that once were called black magic. It should be noted that while this techniques utilize what may be misunderstood as a dark release it is not a form of nature manipulation. Instead techniques placed under this category utilize mostly yin (as opposed yang) and internal energy for different effects. An inability to fully control the most powerful of these techniques can result in a user taking on demonic traits such as grey or black skin and occasionally physiological mutations. It is because of this recoil, called Sakanagi, that Majutsu was considered evil. In reality the effects are the result of channeling incredible amounts of energy throughout the body and that leaks from the chakra network into the bloodstream, bones, and flesh. While many Majutsu techniques can be linked to advanced bloodlines it is not limited to them. Thus it is possible for anyone for nearly anyone to use these techniques. Unfortunately, Majutsu isn't performed with hand seals, since it was developed before the Sage of Six Paths created ninjutsu, and require incantations, called Fuju, to activate. Similarly to ninjutsu and hand seals, a skilled user of Black Magic can skip or shorten an incantation. It should be noted that while these techniques may appear dark in nature they are not malevolent or evil, simply one half of the ancient set of skills that chakra users employed.
