Senjutsu

**Senjutsu** is a rare technique, which only the previous Sennin and high-level youkai were able to learn.

## **Summary**

Naruto explained that senjutsu is different from magic and sorcery with the biggest difference is that it stresses the importance of chakra, their aura, the great original power that flows in one's spirit, e.i. their life-force and turning it into a constant current. Senjutsu is a power that is similar yet different from the magic of Devils and light of Angels. Despite it being incapable of matching the direct destructive power of magic or light, senjutsu makes use of the unknown parts hidden in plants, animals, and people.

For example, if one learned senjutsu, it is stated that they excel at reading the flow of someone's aura, thus letting them grasp their movements from a far distance to a certain degree.

## **Abilities**

Senjutsu is the power to control the flow of life energy or *ki* in living beings. Using it, one can strengthen both their internal and external bodies or even cause vegetation around them to bloom or wither. Senjutsu users are able to sense the ki and auras of others thus letting them track targets from far away distances. It can be used to see through illusions by detecting the flow of the spirit or ki of others.

Senjutsu is also capable of dealing interior damage to others by targeting their blood vessels and internal organs, and through disrupting the ki of their opponent's ki or severing it, it is possible to cause direct damage to their spirit and life-force and using this as an attack could result in killing their opponent. As such, there are very few ways to defend against Senjutsu. Senjutsu can be used to disrupt the aura of others, thereby preventing them from using their abilities. Senjutsu is also capable of forcefully putting others to sleep. By controlling the ki of others, Senjutsu can be used to extract curses and poisons from their bodies.

Senjutsu also has healing capabilities that are effective for either one's physical or mental condition, relieving any fatigue and restoring one's lifespan, however, this method requires physical contact. Koneko states **Bouchujutsu** (房中術, *Bedroom Method*) is the best and fastest method of using the healing abilities of senjutsu, Koneko has explained this method is whenever a woman who specializes in using ki shares her ki with the man and heals their life-force to a greater extent. Senjutsu can also be used to increase the luck of others by controlling the flow of their ki.

Issei elaborates that Kuroka used senjutsu to tell he was a virgin after licking his cheek, however, it is unknown if she was serious or if she was just teasing him.

Senjutsu users also have the power to use Touki, and use it to enhance their strength, speed, and toughness.

Another technique that is exclusive to Youkai such as the Nekomata is known as Kasha, which gathers their ki to create spiritual flames whose colors vary from user to user.

## Weaknesses

According to Koneko, Senjutsu has a fatal flaw, as while it lets the user read and handle spirit power, it could also take in the malice and ill will that flows in the world, potentially corrupting the user as had seemingly happened to Kuroka. However, during Volume 11, Kuroka explained that her actions were done out of protectiveness towards her sister, not out of corruption. No other examples of this corruption have appeared.

## Learning

According to Kuroka, the basics of learning and developing this, is to understand yourself, others, and nature's ki, through focusing one's mind in a zazen posture, quietly releasing their ki, and sensing the natural ki.
