Sealing jutsu
Sealing jutsu (Fūin jutsu) are jutsu that seal something inside objects or living beings. The most common application of this is sealing weapons or other objects within scrolls to efficiently carry a large number of items. Sealing jutsu are also utilized to restrict access to things, such as chakra or entry to a building.
Cursed Seal jutsu
Cursed Seal jutsu (juin jutsu, lit. "cursed seal techniques" or "Technique of the Accursed Mark") are jutsu that use a special "cursed seal" to put someone under the control of the user or elicit an unnatural effect in the one they are placed on. They can be used to cause either pain (including death if the pain is large enough) or invoking various mutations in the recipient.
Kekkei genkai
Kekkei Genkai (Kekkei Genkai "Bloodline Limit") are abilities passed down genetically in specific clans. Most clans have developed special jutsu related to their kekkei genkai and their related jutsu cannot be taught or copied by others, as they require the specific genetic trait to work. Kekkei genkai abilities that work via the user's eye are called "pupil, or ocular, techniques" (dōjutsu), such as the Byakugan, Sharingan, and Rinnegan.
Dead Demon Consuming Seal
The Dead Demon Consuming Seal (Shiki Fūjin, English TV: "Sealing Jutsu: Reaper Death Seal") is a seal created by the Fourth Hokage that invokes the powers of the death god (shinigami, simply dubbed the "reaper" in the English version). Once called upon, the death god hovers behind the user and remains invisible to the opponent until it has grasped their soul. After the sealing is completed the death god consumes the user's soul soon afterwards, killing them. Once a soul has been eaten it resides within the death god's stomach, destined to do battle with its fellow souls for all eternity.
Unlike many of the other seals used throughout the series, the Dead Demon Consuming Seal has served different purposes for each of its uses. When first used by the Fourth, it aided in sealing the Nine-Tailed Demon Fox within Naruto Uzumaki. When later used by the Third Hokage's shadow clones, the Dead Demon Consuming Seal sealed the souls of the First and Second Hokage within the clones' bodies. In this instance, the death god consumed the Hokage's souls in addition to the souls of the clones, suggesting that it consumes whatever souls are present within the user's body. When the actual Third Hokage uses the seal, it sealed Orochimaru's arms, preventing their use.
Puppet Technique
The Puppet Technique (Kugutsu no Jutsu, Viz "Art of the Puppet Master", English TV "Puppet Master Jutsu") was created in order to convert a form of entertainment into a style of combat. The technique utilizes strings of chakra extending from the user's fingers to control a puppet's movements. Those who can effectively use this ability are rare, but once mastered the user can hide in a safe location while his puppet does the work for him. Skilled puppeteers are able to manipulate multiple puppets simultaneously, with Chiyo being able to use each of her ten fingers to control a different puppet. These chakra strings also allow puppeteers to manipulate other people or objects, controlling their movements to help or hinder their progress.
The art of puppetry varies in usage from person to person, as puppets can be equipped with an array of different weapons and tools to make a battle easier. Puppeteers can also combine the abilities of their puppets to increase their effectiveness; Kankuro, for example, can use one of his puppets to capture an enemy while a second bombards them with weapons, killing them. Standard puppets, however, are limited to attacks not dependent on chakra, as soulless beings cannot utilize it. Sasori has created a workaround for this shortcoming by converting the body of a still-living person into a puppet. Because they were once human, these puppets are able to perform jutsu, giving them a drastic advantage over other puppets.
Summoning Technique
Summons are typically called forth in a puff of smoke with the Summoning Technique (Kuchiyose no Jutsu, Viz "Shinobi Conjuration", English TV: "Summoning Jutsu"), or any number of variations thereof. Before a summoning can be performed, the user signs a contract with their own blood, each contract differing depending on what creature is to be summoned. Once this is done, the summoner need only perform the proper hand seals and offer a few additional drops of blood with the same hand they signed the contract with to perform the summon. The amount of chakra offered at this time is directly proportionate to the size of the summoned creature. Summons have their own abilities that they can use by themselves or in conjunction with the summoner. Some summons are so powerful that they may even challenge the summoner, or will demand something in order to contribute to the battle.
In certain cases, it is also possible to summon inanimate objects, as Orochimaru and Sakon and Ukon do with the Rashōmon gate. As with living summons, inanimate summons also require a blood sacrifice.
