Patting you on the head a tear falls from my eye as I inhale the snot back into my nose.
It's not your fault young one. I'll guide you to a safe heaven. Ninjutsu is the initial chakra manipulation art known to all shinobi in some way or another. Ninjutsu allows a shinobi to do something they ordinarly could not perform without it. Ninjutsu can range from walking on water, transforming oneself to another appearance, healing others, summoning things or animals, manipulating ones surrounding, to even nature transformation which we use when utilizing the basic 5 elements.
Chakra is the fuel for every ninjutsu and is within every shinobi at various amounts moving through their chakra pathways throughout their body. Chakra is created by mixing ones spiritual energy with ones physical energy creating something new. It can be increased through meditation, physical training, and practice. It can be easily altered and transformed into something new, but that's a different story.
Handseals are used to help the user mold the chakra for the technique being used and is a major part in all ninjutsu. The more expierence a shinobi has in an area of ninjutsu, the more likely they are to use jutsu without the need of waving the entire amount of hand seals needed for the jutsu.
This field of training will focus primarily on the shape manipulation part of ninjutsu which inolves controlling the form, movement, and potency of chakra being used on either an item or within thin air itself. Now are you ready?
