A kind of fūinjutsu that involves sealing a technique's effects within a specific location. As it is tailored for fire release ninjutsu, it requires a caster well-versed in the exacting art of "Sealing Formulas", as well as in ninjutsu. The jutsu-sealing space in the scroll is left blank, for the formula to be inscribed in with a brush. After performing the needed hand seals, vapour appears from the scroll, and envelops the flames. They are sucked in towards the scroll, and the appearance of the kanji for seal (封) certifies the technique's completion. Once the sealing is performed, the technique's effects cannot be released anew as long as an unsealing technique is not applied. It is an effective technique to circumvent any secondary damage a dangerous enemy technique might cause. It is even capable of sealing the black flames of Amaterasu. It is stated that Sageru Uzumaki has learned this technique during his training with Sannoto Senju.
When Kyōshi Takamori uses this technique in conjunction with his Ceremonial Sword of Sealing he's able to seal flames at an incredibly high rate. In doing so he is able to utilize the technique in a defensive manner. Additionally, since the flames are sealed directly into the sword, he's also able to unseal the fire at his own discretion.
Improvement[]
Later Sageru created his own version of this technique by using multiple scrolls which already has the seal,by activating the seal he can seal away an incoming fire based jutsu from the enemy.Which he had already demonstrated to Sannoto during their training where Sannoto created multiple clones and bombarded him with fire release jutsu's,not only he was able to seal all the fire jutsu's but also throw back some fire balls back at them by simply reverting the seals.
