Sukuchijutsu

Shukuchijutsu (縮地術, Reduced Earth Techniques) is an ancient martial arts that had vanished with time. It is an art which had been forgotten with the arrival of the intricacies of chakra. It mainly revolves around getting to the enemy's blind spot, capitalizing on it as well as removing one's own blind spot. These arts had been highly coveted prior to the debut of ninjutsu as well as the other forms of combat thereinafter, courtesy of the introduction of chakra to the human populace.

History
It was an era of war, where fathers, mothers, brothers and sisters alike were lost. The endless bloodshed that eventually gave birth to the chakra fruit of the God Tree. However, prior to its introduction into mankind's grasp, the humans have endlessly fought against its other for their own selfish ends. Their lust for hegemony clouded them from the path to peace. However, not all were that way. Some monks and grand masters had saw the world in a better perspective. They were in tune with the universe and the flow of the energies in which it is composed of. They had a higher state of wisdom and knowledge, and they shared this wisdom to the others through the use of martial arts. Some practiced the basics of ninjutsu, which was light-years behind in comparison to it's current level post-chakra augmentation. Some practiced various forms of kata. However, a single temple had used one of the most feared forms of martial arts. The sukuchijutsu had been one of the most fearsome forms of these arts, presumed by many to make them "gods". This fame, however, also lead to danger, as the greedy beings sought predominance, and wished to use this art as their tool to do so. An unknown army had invaded the temple, seeking the secrets of the techniques. They had killed the monks through the use of numbers, overwhelming the temple grand masters. However, one of them had remained, and hid the secrets to the art deep underground. He burnt an empty scroll, successfully tricking the armada into defeat, however, not before his own demise.

Centuries later, more than a millenium, from the exact place where the temple was built, the village hidden in the mist was formed. It remained doormant for decades, until the scroll was found by Heiwa by pure accident. Whilst touring around the Kage residence, he fell in a faulty hole in the floor due to his own ignorance, where he found a scroll containing the art, as well as it's history. He had began to learn it through the scroll, and had been more in-tune with the universe, being granted knowledge about it's purpose and why it had been long forgotten.
