Truth-Seeking Ball (Ten Tails)

Shinra Banshō is the signature technique of Ryun Uchiha, using the advanced nature of Yin-Yang Release, combined with his Rinnegan. It is based on the of the Ten-Tails' jinchūriki, using the same mechanics. According to Fujoshi Shihōin, it is the purest manipulation of Yin-Yang Release, going as far as to dub it simply the.

Background
Ryun based this technique off of the Ten-Tails' ability to manipulate Yin-Yang chakra in such a fashion, through its jinchūriki. He began to develop this technique shortly after Yamagakure's creation, however, the technique wouldn't form because of the immense amount of chakra required to stabilize and control it. Without the Ten-Tails' gargantuan reserves, this made Ryun shelf the technique for many years. However, after studying the Hachiman kekkei genkai, which allows the user to shape chakra into weapons, that appeared within some clans of the Land of Mountains, Ryun once more began to develop the technique.

Upon awakening the Rinnegan, Ryun learned that he could use the eyes to measure the ratio of chakra he was using, as well as learn the additional natures needed to form Yin-Yang Release, allowing him to complete the technique. He then spent years developing each variation, as well as perfecting his chakra control to allow him to use the technique for longer and longer periods of time.

Usage
Using yin and yang together, the user creates a small orb of black chakra. This orb can be expanded or contracted at will, completely disintegrating anything and everything it comes into contact with, including, but not limited to, ninjutsu and physical attacks. Upon coming into contact with the target, the ball will explode, causing tremendous damage to the immediate surroundings. As a technique that can nullify and eliminate ninjutsu, even chakra absorption techniques are useless against it. Additionally, it can be into a variety of forms to fit the user's situation; each form producing a different result.

Advantages
As a Yin-Yang technique, techniques such as Impure World Reincarnation become useless, as even the immortal bodies of the reanimation technique are rendered mortal before its ability. The technique is highly effective if combating a shinobi specializing in ninjutsu or taijutsu, as such attacks have no meaning when used against it. As Yin-Yang Release is made up of at least four or more natures, it has no natural weakness to any particular nature, making it useful against any nature that may be used against the user.

Influences
The name is taken from, a Japanese four-character idiom and homophone variant of , a Buddhist idiom which has come to mean "All of Nature" or "All of Creation".
