Fuuinjutsu Techniques

~D-rank~


Name: Generic Sealing
Rank: D
Type: Fuinjutsu
Element: n/A
Range: Close
Description: With this technique the user is able to store a variety objects or jutsu within a scroll or other surfaces with the seal inscribed, depending on the user's skill with Fuuinjutsu. While sealing an object takes a considerable amount of concentration for those unskilled with Fuuinjutsu, unsealing an object is simple enough and can be performed on the fly so long as the symbol is accessible to the user and thus making it possible to unseal a weapon in the midst of battle. Storing jutsu requires chakra consumption 1.5x greater than the normal jutsu cost, and must be done during a battle thread. Sealing in battle, however, is not possible for those who are unskilled in Fuuinjutsu.


~C-rank~


Name: Finger Carving Seal
Rank: C
Type: Fuinjutsu
Element: None
Range: Close
Description: The user concentrates chakra into their finger and using the heat from that, can apply writing of whatever they want to a surface. This technique however requires them to be very delicate with their chakra control.


~B-rank~


Name: Cloth Binding Technique
Rank: B
Type: Fuinjutsu
Element: N/A
Range: Depends on length of cloth
Speed: Cloth moves at speed of 50
Description: The user uses a giant roll of cloth to tightly wrap up the intended opponent, completely immobilising them, thus preventing them from moving or using any techniques. The ability itself is versatile as once completed, the addition of further seals can be placed on top of the bound victims, preventing them from even being summoned while in effect. Sealing tag has to be on cloth beforehand

Name: Fire Sealing Method
Rank: B
Type: Fuinjutsu
Element: None
Range: Five meters
Handseals: Rat → Bird → Technique specific seal → Tiger
Description: 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, chakra-like 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.
Weakness: Katon that are higher than B-rank requires chakra consumption equivalent to the chakra used to produce the Katon that is being sealed.

Name: Sealed Iron Wall
Rank: B
Type: Fuinjutsu
Element: None
Range: Close
Handseals: Snake, Rat, Tiger.
Description: A seal placed on the Fire Temple's gate, in order to defend against intruders from the outside world. The two statues placed on either side of the gate form a barrier. The seal can only be cancelled by pouring in the Gift of the Hermit Group, special chakra peculiar to the ninja monks of the Fire Temple. The user can manipulate it so that only particular chakras can open the gate, as well.


~A-rank~


Name: Five Elements Seal/Unseal
Rank: A
Type: Fuinjutsu
Element: None
Range: Close
Description: Five Elements Seal is a technique which produces a powerful seal that is used to block or disturb the target's chakra flow. Once the seal is completed, the target will become unconscious and unable to fight for a short time. Orochimaru performed this technique to tamper with Naruto Uzumaki's seal. The original seal allowed a small amount of the Nine-Tails' chakra to always mix into Naruto's, but the additional seal disturbs this, preventing Naruto from using the Nine-Tails' chakra or even controlling his own chakra properly. This is because an odd-numbered seal creates an imbalance when placed on top of an even-numbered seal. When Orochimaru later notices that the seal has been removed, he remarks that there are very few ninja capable of doing so, like Jiraiya.

Five Elements Unseal is a direct counterpart technique of Five Elements Seal. This technique can be used to remove fūinjutsu of up to equal power, like its counterpart. The sealing and unsealing techniques have to be purchased/trained separately.

Name: Contract Seal
Rank: A
Type: Fuinjutsu
Element: None
Range: Close
Handseals: Tiger, Monkey, Ram.
Description: When the user implements this fūinjutsu on a summoner, it removes any direct control the summoner has over a summoned creature. Direct contact is required for the implementation of the seal.
Weakness: Though the Contract Seal removes the summoner's ability to control its summon, it does not give the user of the fūinjutsu the ability to control the summon in turn. Thus, this is usually used when a summon is being controlled against its will, as summons who have developed a natural bond with its summoner will be unaffected by this, although the summon will be sent back to its world and be unable to be summoned back for a remainder of time.

Name: Iron Armour Seal
Rank: A
Type: Fuinjutsu
Element: None
Range: -
Handseals: Tiger, Rat, Dragon, Monkey, Rat, Tiger, Bird, Rabbit, Snake.
Description: Iron Armour Seal was the fūinjutsu used by Kumogakure to seal Gyūki into its respective hosts.
The seal itself takes the form of the kanji for "iron" (鉄, tetsu) and is usually printed somewhere on the jinchūriki's body: Killer B's right shoulder, and Fukai's chest. Not much else is known about the seal, besides the fact that it was stated by B to be of lower-quality and weaker than the Four Symbols Seal, which was used to seal Kurama inside of Naruto Uzumaki.

Name: Evil Sealing Method
Rank: A
Type: Fuinjutsu
Element: None
Range: Close
Handseals: Hare → Snake → Horse → Ram → Bird → Tiger → Hare → Snake → Horse → Ram → Bird → Tiger → Hare → Snake → Horse → Ram → Bird → Dog → Rat
Description: This technique is used to suppress technique-induced marks on a person. Marks of weaker power can be completely suppressed by this technique alone, but for marks of higher power, like Sasuke Uchiha's Cursed Seal of Heaven, it will cause the seal's power to become dependent on the recipient's own willpower to some extent, especially if the sealer is not experienced enough to strengthen the seal with his own power. It is also capable of holding back certain kekkei genkai, such as that of the Kurama clan as seen when Kurenai tried to do this.

According to Kakashi, this technique is quick, but painful. The seal can be removed at any time by the caster or whoever the seal is on, as demonstrated during Sasuke's battle with Naruto in the Valley of the End. Since this seal relies on the will of the individual on whom it is placed, the affected may be able to will it away without an unsealing technique.

Preparation for this technique requires two concentric circles with kunai placed in intervals along the circumference, in addition to a number of characters written in blood that radiate out from the centre of the cursed seal.


Name: Evil Releasing Method
Rank: A
Type: Fuinjutsu
Element: None
Range: Close
Handseals: Tiger → Snake → Horse → Ram → Tiger → Hare → Rat
Description: The Evil Releasing Method is a direct counterpart to the Evil Sealing Method, this technique is used to release technique-induced seals [up to S-rank] on a person rather than sealing it. Compared to the Evil Sealing Method, the Evil Releasing Method requires far less preparation.  

Name: Sealing Technique: Lion Closing Roar
Rank: A
Type: Fuinjutsu
Element: None
Range: Long (20m)
Speed: 100
Description: This sealing technique completely blocks the target's chakra with a sealing formula (封印式, fūin-shiki) drawn on the ground or a wall. This is done by closing all the tenketsu of the person caught in the middle. When the target is sealed, a stylised kanji for "close" or "shut" (閉, hei) appears in the middle of the sealing formula.
Weakness: To successfully seal the target, one has to get them exactly inside the sealing formula (right in the middle). This requires great accuracy and is very difficult. Various methods can be used to make this easier. For instance, one can prepare a puppet or a ninja tool like the Lion-Headed Kannon with this sealing formula.


~S-rank~


Name: Four Symbols Seal
Rank: S
Type: Fuinjutsu
Element: None
Range: -
Description: This is a sealing technique based on the fūinjutsu of Uzushiogakure's Uzumaki clan. The sealing formula is used to seal any target into a human body or an object, and is mainly used when a giant enemy or evil spirit needs to be sealed away. To use it, it is necessary for the user to have great ability.

When two Four Symbols Seals are used together, they form the Eight Trigrams Sealing Style. When Minato sealed Kurama into Naruto Uzumaki, he left an opening at the space where the two seals met, allowing Kurama's chakra to mix with Naruto's own. Minato also left behind a key with Gerotora, which could be used to freely manipulate the seal.

Name: Reverse Four Symbols Seal
Rank: S
Type: Fuinjutsu
Element: None
Range: 25 meter radius
Speed: 100
Description: This technique is a fūinjutsu that the user places across their chest, and sets it to activate upon their death. It releases four symbols from the user's body that then forms a large, black sphere around them. Anything caught inside the sphere's area is then drawn in and sealed within the user's corpse

Name: Eight Trigrams Sealing Style
Rank: S
Type: Fuinjutsu
Element: None
Range: -
Description: This technique was used by Minato Namikaze to help Naruto Uzumaki access the chakra of the Nine-Tails sealed within him. To perform the technique, the user must first summon a ceremonial throne and place the target on it. The seal was not automatically visible on Naruto's belly, but became perceptible whenever he drew on the fox's chakra.
