Tsuchikage’s Weight Rock Ninjutsu

Tsuchikage's Flight

Earth Release: Added-Weight Rock Technique and Earth Release: Light-Weight Rock Technique are a pair of fundamentally similar B-rank ninjutsu but with the exact opposite effect.

The user is able to use earth natured chakra to increase or decrease the effect of gravity upon a target’s mass, thereby manipulating their weight. They can be used on living and non-living targets as long as the caster touches the target or even just perform it on their own body. Its chakra cost depends on how far the target’s weight is changed and the amount of mass the target has.

Earth Release: Added-Weight Rock Technique is used to increase the target’s weight.

It can make a weapon weigh so much that it cannot be lifted by its wielder to render them unarmed, make a door so heavy that it becomes impossible to open it without force or cause a building to collapse on itself by becoming heavier than its construction can withstand. Enemies can be rendered immobile as they become too heavy to move under the force of gravity, essentially making them helpless as they cannot escape or fight back.

Using it on a weapon can also benefit the caster by increasing its weight after building enough momentum to unleash greater physical force then restoring its weight to avoid straining themselves.

The caster can accomplish something similar by using the technique on their own body to dramatically increases the power of their strikes at the cost of lowering their mobility. This technique makes it possible for even for someone physically feeble to release a powerful blow. They could literally crush their enemies from the weight of their body and withstand blows that would ordinarily knock them down without budging an inch.

Earth Release: Light-Weight Rock Technique is used to decrease the target’s weight.

Objects that would normally be too heavy to lift can be made several times lighter so that even something as large as an island can weigh little more than a pebble. Or using it on an opponent’s weapon can make it so light that the wielder struggles to compensate and being hit by one is like being hit by a feather.

This version is especially effective when used on living beings. With a lightened body, one can increase the speed of their movements and strikes (in exchange for being far weaker), leap over greater distances or fall from greater heights unharmed and walk through surfaces like water without needing chakra.

But the ninjutsu’s true potential is realised when it it used to lighten both the user’s body and the atmosphere around them which practically neutralizes gravity’s hold over them and allows them to fly through the sky without aid. This, too, can be used on other people so that entire teams would be able to fly alongside the caster to outmanoeuvre their enemies.

These two techniques were originally invented by the First Tsuchikage Ishikawa and he was notoriously secretive about their mechanics. Realistically, any jounin with an earth nature could potentially learn but he had no desire to make it common knowledge even among the elite ranks. Instead he taught it only to his second-in-command and successor, Muu, who then taught it his own successor, Oonoki.

Ishikawa was indisputable the master of these two techniques as they were foundation of his fighting style. In combat, he would switch between being lightweight and a heavyweight in an instant to perfectly combine supernatural speed with supernatural force in blows that could hardly be stopped. And his aerial dominance allowed him to fight in ways that few others could counter such as dropping rocks as heavy as mountains or falling from the heavens himself to crush everything below.

These techniques, combined with his other speciality, are why he became known as the Meteor.

It became an unspoken agreement between him and his successors that only those worthy of the title of Tsuchikage would be given the privilege of this learning this techniques. And so the ability of unaided flight and the techniques that made it possible became a symbol of Iwagakure’s strongest shinobi.
