Truth-Seeking Balls are spheres of black, malleable chakra that are comprised of at least four different nature transformations, as well as natural energy, and with complete mastery are capable of negating ninjutsu.
The Truth-Seeking Balls are highly versatile and can be used for offensive, defensive and supplementary purposes. By applying shape transformation, the user can alter the balls into various weapons. This can be done by having the balls pierce through holes that temporarily form in the user's hands, though they can also be shaped through other means. The balls can wrap around the user to act as a defensive shield, or be launched to serve as high-speed projectiles. They are also capable of causing massive explosions by rapidly expanding their size, a lethal attack which can damage the user's own body.
According to Hiruzen Sarutobi, the technique acts on a similar basis to Dust Release, but on a greater level in terms of shape transformation, allowing it to constantly be used for either offensive or defensive purposes. Hiruzen also noted that, since the substance is likely a combination of at least four nature transformations, it is beyond both kekkei genkai and kekkei tōta. When Obito took control of the Ten-Tails' power, Tobirama Senju stated that this technique could make use of Yin–Yang Release, which allows it to nullify all ninjutsu. He continued to state that if the technique were to strike a reincarnated individual, the damage they receive would not recover and they could die as it neutralises their immortality. However, to nullify ninjutsu, the user seemingly requires a certain amount of focus, as Obito's Truth-Seeking Balls did not nullify ninjutsu prior to him gaining control over the Ten-Tails' power.
Obito used the black substance as chakra receivers, shooting them in six directions to perform the Six Red Yang Formation, while Naruto used the balls as Tailed Beast Balls to create massive explosions. The balls can also be used to create the Sword of Nunoboko. The black substance is highly durable, only taking damage from powerful techniques such as the Evening Elephant and a senjutsu-enhanced Tailed Beast Ball.
This technique can be manipulated into a variety of shapes for various purposes.
According to Minato Namikaze, the user can only control the chakra within 70 metres of their location. He also noted that the chakra simply exists, and can't be deactivated. Hiruzen noted that there is likely a limit to the amount of time that the balls can take on another form. After seeing the effects of Gamakichi's natural energy-imbued technique on Obito, Naruto and Tobirama discovered that the balls were incapable of negating senjutsu. It was also shown that when the transformed balls come in direct contact with natural energy-based techniques, their form becomes disrupted.
- When a jinchūriki of the Ten-Tails gains control over the beast, the shakujō variant seems to instinctively form in their hand. Obito and Madara each wielded one half of Hagoromo's complete shakujō.
