Description: Using this technique small objects and even living non-sentient things can be stored within scrolls, and can be released when the scroll is opened or meets a specific condition. It is possible to seal ninjutsu into a scroll. Techniques sealed via the enclosing technique may also be primed to activate on a certain condition. Ninjutsu up to C-rank can be sealed.
Weaknesses: If a Fuuinjutsu user identifies a seal created by this technique they will know the contents erasing any potential trap that may be set up.

Description: This technique creates a barrier around a place by placing four "forbidden" (禁, kin) tags in different locations surrounding the place to be protected, a fifth tag on the location to be protected. The tags are placed on flat surfaces, and are connected with the user's chakra. This technique turns the entire range surrounded by the tags into a barrier space, and inside the space, the material's destruction is "forbidden". Using any kind of physical attack to try and destroy something in the barrier is folly, as it will only lead to injury. To cancel this, it is necessary to search for the four tags and tear them off simultaneously. Even if the tags are removed, there is a final obstacle. The user can add a trap that will create perfect copies of those who have removed the seal, preventing them from returning immediately. Those who have removed the seal must spend two posts fighting their copies before defeating them.

Description: The Explosive Tag Seal is a well-known Fuuinjutsu most commonly used to produce explosive tags commonly stored in the marketplace. This technique works by sealing the user's chakra and compressing it (5 CP). When the chakra is released it reacts violently with the environment resulting in a small, but potent blast radius of five meters. There are two ways the explosive can be activated, both costing no chakra:

1.) Igniting the tag with chakra or heat. This results in a slow burn and a four second delay allowing the user to benefit from the delay by throwing them greater distances, how far dependent on the user's method.

2.) Detonating the tag remotely using chakra. To do this, the user must make direct contact with the explosive tag to apply their chakra to the tag. This allows them to detonate the explosive tag remotely with the Snake hand seal. The range on this method is only twenty meters from the user.

Weaknesses: Lit explosive tags can be deactivate by applying chakra to the tag before the seal is burned and the explosion is released.

Description: In order to enter the boundary created by the Five-Seal Barrier without dispelling the technique, one has to use the Five-Seal Barrier Pass Technique. The user probes their chakra out into the barrier, and essentially requests permission to enter. Whoever created the Five-Seal Barrier may then decide whether to allow them entry or not.

Description: This is a special "ninja tool summon" that allows the user to seal ninja tools like swords or kunai into a scroll or their clothes beforehand, allowing them to be called upon when needed. The ninja tools can be summoned in an instant just by touching the sealing "marks" which can be drawn anywhere. The greatest advantage of this technique is that the time between taking out a ninja tool, taking the right stance and actually throwing it is greatly reduced. Also when a weapon such as a fūma shuriken is summoned, the time needed to throw it can be further shortened by having prepared the weapon in its fully extended form beforehand. Furthermore, because the summoned ninja tools can remain hidden until right before they are used there are an exceptional number of possible tactics. One hundred ninja tools can be stored within each sealing mark, which can make the efficiency of this technique last longer. Five tools can be summons per unseal.
Weaknesses: Just like with any Fuuinjutsu, if the medium in which your seal in place on is destroyed, everything stored within the seal is lost permanently.

Skill: Fuuinjutsu
Classification: Exclusive (Sunagakure)
Requirements: Sealing Cloth
Parent Technique: -
Hand Seals: -
Description: The user makes physical contact with a giant roll of cloth and causes it to rapidly unravel, traveling at the indicated speed towards the target and wrapping it up in a large cocoon made entirely of the cloth. Once fully encapsulated, the target will be rendered immobile, and should the user choose, sealing tags may also be added to ensure that the target cannot be summoned or unwrapped until those tags are removed.
Weaknesses: As the technique uses cloth as a medium, it is weak to fire and sharp edges. Given the volume of cloth being used, however, it may take a swift hand to cut it all.

Parent Technique: N/A
Hand Seals: N/A
Description: This technique molds the user's chakra into extremely durable chains which can be used for various purposes including restraint similar to the Adamantine Sealing Chains technique. Much like its counterpart, it can be used offensively, as well as can neutralise a target by binding and nullifying their chakra on contact. These chains are not as strong however and as such restrain at a Strength of A++. The chains also are incapable of forming a protective barrier which limits their versatility in comparison to Adamantine Sealing Chains. Like the original the the chain's speed and accuracy is governed by the Coordination stat.
Weaknesses: Because there is Fuuinjutsu underlying the chakra chains, they can be nullified like any other fuuinjutsu in accordance with the sealing breaking rules. The chains can also be broken by S Tier Strength or greater.

Parent Technique: N/A
Hand Seals: N/A
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. To successfully seal the target, one has to get them exactly inside the sealing formula. This may require great accuracy and can prove very difficult in most fight scenarios. 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.
Weaknesses: If the target is removed from the seal, then their tenketsu will re-open allowing them to utilize chakra once more.

Hand Seals: Technique-specific seal
Description: Once the seal is completed, the target will become unconscious and unable to fight for a short time (five posts.) A person afflicted with this seal will be unable to mold chakra properly making the performance of techniques B-rank or higher impossible. This technique can also be used to disrupt Jinchurikki seals. Jinchurikki afflicted with this seal are unable to use Chakra Access in any form.
Weaknesses: This seal can be erased via the Five Elements Unseal Technique. This technique only blocks chakra. This means Taijutsu, Bukijutsu, Kenjutsu, and any other group or type of technique that uses stamina are unaffected.

Description: When the user implements this fūinjutsu on a summoner, it removes any direct control the summoner has over a summoned creature. Close contact is required for the implementation of the seal. This technique is primarily used to free a summon or creature (included Tailed Beast) from someone controlling it. 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. It is important to note that this technique has limited application on those creatures under Kuchiyose Contract who fight of their own free will thereby largely restricting its use to those creatures that have been robbed of their free will. As a side effect, this technique can also increase the post limit that summons have by one post or it can instantly send a summon back to where it came from thereby forcing the summoner to perform Kuchiyose again.
Weaknesses: Does not in of itself give the user the ability to control the summon.

Description: A secondary trap is laid under the Five-Seal Barrier. This technique is automatically started when the "forbidden" tags are removed. An exact copy of the person who removed the tag appears with their appearance, weapons, battle skills, and so on. Because the double has a fixed amount of stamina and doesn't feel exhaustion, it has an advantage in a drawn-out battle. Those who have removed the seal must spend two posts fighting their copies before defeating them.
Weaknesses: The duplicate can be defeated via auto-hit by the user after two posts of combat.

Description: Similar to the Cursed Tongue Eradication Seal, this seal can also be applied during combat, and can secretly be placed on the opponent's body. When the user activates it, the curse seal's marks spread around the opponent's body, paralyzing them. However, one can break free from the seal with a A Rank Release of chakra.
Weaknesses: Every time the technique is applied against an opponent by the same user, they can use their prior knowledge of the releasing mechanics to reduce the amount of chakra needed to end the curse by one rank.

Hand Seals: N/A
Description: By placing a mark on a person in a ritualistic method, this seal will force the user to perform any technique that the user or target knows. If the technique requires handsigns then the user will be forced to perform handsigns (assuming that's not a physical impossibility). The seal can be activated at will or under a timed release schedule (the detonation time must be specified at the moment of creation via a post count or IRL time). The seal will remain primed even if the person is tortured, put under a trance, or unconscious. This is meant to catch an enemy when their guard is down. The user/target must hold the chakra for techniques primed using Time-Release in escrow meaning this chakra is unavailable to them for in their regular chakra pool. The chakra can only be released/accessed when the seal is activated or when it is erased.
Weaknesses: Only three Time Release seals can be created and primed at one time. If a fourth is created then the oldest created seal will automatically be erased.

Parent Technique: N/A
Hand Seals: N/A
Description: This technique molds the user's chakra into extremely durable chains which can be used for various purposes, such as directly combating or physically restraining their targets — foes even as powerful as a tailed beast. These chains could also be used to bind the chakra of a target, completely neutralizing their ability to use chakra based techniques. The user can also manipulate the chains to erect a barrier. This barrier has X-grade hardness in terms of durability. The user's ability to control the chains is governed by the user's Coordination stat. The chains have a Strength of S++ making it extremely difficult for almost any shinobi to break out of them using raw strength.
Weaknesses: Because there is Fuuinjutsu underlying the chakra chains, they can be nullified like any other fuuinjutsu in accordance with the sealing breaking rules. The chains can also be broken by X Tier Strength or greater.

Description: Iron Armour Seal is the fūinjutsu used by Kumogakure to seal a Bijuu into a host. The seal itself takes the form of the kanji for "iron" (鉄, tetsu) and is usually printed somewhere on the jinchūriki's body.
Weaknesses: The Iron Armour Seal like any seal designed to contain Bijuu is impermanent and enough wear and tear will cause it break as per the Bijuu sealing rules.

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 such as a Bijuu.
Weaknesses: The Four Symbols Seal like any seal designed to contain Bijuu is impermanent and enough wear and tear will cause it break as per the Bijuu sealing rules.

Name: Eight Trigrams Sealing Style
Rank: S
Activation Cost: 50
Range: Contact
Speed: -
Element: N/A
Skill: Fuuinjutsu
Classification: Exclusive (Konoha)
Requirements: A-tier Intelligence
Parent Technique: Four Symbols Seal
Hand Seals: N/A
Description: To perform the technique, the user must first have a ceremonial throne and place the target on it. The Eight Trigram Sealing Style is performed by placing two interlocking Four Symbol Seals ontop of each other and leaving a small gap between the sealing mechanisms. This unique and powerful style of sealing Bijuu affords several bonuses to the jinchurikki:

• When the seal's 500 point value is depleted, it automatically performs a one time restoration whereby the seal is immediately brought back to full strength without the normal reinforcement penalty.
  
• The Eight Trigram Seal has a bit of a gap between the two seals allowing Chakra Access to flow more generously and efficiently. It reduces the 100 Experience cost for a post of chakra access by 25 exp. One post of chakra access thus costs 75 Experience for those with this seal.
  
• The Eight Trigram Seal can be locked and the key stored in the form of a scroll. Locking the seal has the effect of blocking of the Jinchurikki from the corrosive nature of the bijuu's chakra. This halts any chance of seal deterioration that would result from use but it has the side effect of also blocking the Jinchurikki from all the abilities that come with being a host (Healing, Chakra Mode, Chakra Access, Tailed Beast Transformation, Initial Jinchurikki Mode, etc etc).
  

The user can also place a bit of their subconscious in the seal. This subconscious manifestation can be triggered at a certain point in the seal's weakening (must be specified at the time of sealing). This manifestation can last for up to 10 posts and can provide advice, knowledge, and training as though the user were present within the host's mind. This subconscious manifestation can exist even though the user has died.
Weaknesses: Like all seals it is vulnerable to eventual wear and tear. While the seal may be reinforced over the course of the first lifespan of the seal, it cannot do so during the second lifespan. After the one time replenishment that restores it back to 500, the Eight Trigrams Seal will not be able to be reinforced and must be re-applied entirely should the Jinchurikki require it.

Description: The Reverse Four Symbols Sealing is a fūinjutsu and a stronger version of the Four Symbols Seal. The user places the seal 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.
Weaknesses: Can only be activated before death.

Description: The Self-Repairing Barrier is a Cooperation Fuuinjutsu that by linking chakra from four PC shinobi (although shadow clones created by PC may be used), will create a barrier which if damaged, will constantly repair itself with said chakra that emanates from their bodies. The barrier also prevents those outside of it from sensing anything inside it through traditional methods (Sensory/Dojutsu). The users can erect as much as 36 barriers, with the highest number being able to stop and contain any individual jinchūriki. Barriers are erected in sets of nine for a maximum of thirty six. Every 9 barriers costs 5 Stamina points of upkeep per shinobi. A single set of nine barriers can be destroyed by a single Tailed Beast Bomb, S-rank Ninjutsu, and/or S++ Strength. If the user has 18 barriers for example, even after destroying the first nine the second nine will remain in place while the destroyed set repairs itself in a single post so long as the upkeep is paid. This would require four S-rank Ninjutsu launched at the same time, four simultaneous S++ Tier Strength blows or four simultaneous Bijuu Bombs to destroy a maximum of 36 barriers.
Weaknesses: X Tier attacks are orders of magnitude stronger than what this barrier is designed to defend against. Any offensive X Rank technique or X Tiered Strength blow will instantly shatter all thirty six barriers.

Parent Technique: N/A
Hand Seals: Snake → Boar → Ram → Rabbit → Dog → Rat → Bird → Horse → Snake → Clap Hands
Description: After the hand seals are performed, the user's soul is partly separated from their body and suspended behind them. Behind their soul appears the Shinigami, which restrains their soul with its hair. Only the summoner is able to see the Shinigami at this point. Eventually, the Shinigami wraps its left arm with prayer beads and chants unintelligibly until a cursed seal appears on its arm. It then drives its arm into the summoner's soul, thus allowing the summoner to call upon the Shinigami to seal a target. The technique can either be initiated at close-range, immobilising the target while their soul is extracted, or from a longer range. The Shinigami's arm emerges from the summoner's body and grasps the soul of the target, enabling the target to see the Shinigami as well. Once the target's soul is grasped, the summoner can remove the target's soul and seal it into their own body. The user is able to seal multiple souls by using this technique in conjunction with the Shadow Clone Technique.The sealing, however, is not necessarily complete nor automatic; It requires physical strength to fully extract someone's soul from their body. This is governed by a Strength vs Strength matchup whereby the character with the greater Strength will prevail. If the difference between the two character's strength is one tier or less however, the user will have the option of sealing two of the opponent's limbs, permanently neutralizing them. After the sealing is performed, a mark appears on the summoner's stomach that is similar in appearance to the Eight Trigrams Sealing Style. For a few moments afterwards the summoner can continue moving and speaking, allowing them to finish any lingering business they may have. Shortly afterwards the Shinigami will consume their soul and the soul of their target(s), ending their life. The souls of those trapped within the Shinigami's stomach cannot enter the Pure Land and are destined to fight with their victims for all eternity.
Weaknesses: This technique can be undone by the Dead Demon Consuming Seal: Release

Description: This technique involves invoking the Shinigami using a mask from the Uzumaki Clan's Mask Storage Temple. From there, the summoner is possessed by the Shinigami allowing them control over it, they can then force it to cut its own stomach resulting in the release of the souls sealed inside. Due to the possession however, the same damage will reflect on the invoker's own body.

After the souls are released, the person is free to do as they please with the souls. Orochimaru used this technique to free the souls of the Hokage along with that of his arms and then reincarnate them.
Weaknesses: Only the Uzumaki are in possession of the Mask necessary for this technique
