Supernatural Sealing

Go To

This is the power or technique that lets someone seal objects. This results in imprisoning beings, nullifying powers, and/or locking away objects within another object and releasing them when needed. Depending on the strength of the user, the seals can weaken over time and cannot seal sufficiently powerful objects. If the sealed object has a power, the user may be able to tap into it. Oftentimes a strong enough seal will require Power at a Price or the continued vigilance of a Barrier Maiden. May involve the use of mediums such as talismans and geometric figures.

Can overlap with Pocket Dimension and Trapped in the Host. May result in a Captured Super-Entity and Sealed Inside a Person-Shaped Can, Sealed Good in a Can, or Sealed Evil in a Can. See also Seal the Breach in cases where the object needed to be sealed is a supernatural dimensional gate or otherwise.

  • Ayakashi Triangle:
  • Secre Swallowtail from Black Clover uses Sealing Magic. Originally, she thought that her magic could only open and close objects like locks, making it useless. However, she learned to seal magic into objects and even close wounds and seal damage. Using the power of Forbidden Magic permanently affected her Sealing Magic, letting her imprison a devil for centuries.
  • Bleach:
    • Kisuke Urahara uses the Kido Kyujurokkei Kakafumetsu to seal the now immortal Aizen after he merges with the Hogyoku, piercing him from the inside out with cross-shaped beams which merge into a barrier that seals him inside with his powers weakened.
    • Yukio Hans Voralberna can use his Fullbring Invaders Must Die to seal people in a digital space where their spiritual pressure is completely cut off from the outside world, which is referred to as a "Save" on his handheld video game console.
  • In Blood Blockade Battlefront, Klaus Von Reinherz can use the technique Pattern 999 - Ewigkeit Gefängnis to seal away a Blood Breed Elder in a small crucifux through invoking their true name.
  • This is the entire point of Cardcaptor Sakura. Sakura accidentally released the cards, so she has to go capture them again. Clow Cards need a master or they run amok. That's why Clow Reed sealed them in the first place, in preparation for the time after his death. When Sakura seals a card she becomes its master. This drains her magic energy, but as her power increases the recovery time shortens.
  • Sakura in The Demon Girl Next Door is a Magical Girl who specialized in seals, and not only about sealing per se—she is also adept at tampering other magical seals.
  • Dragon Ball combines this trope with Dangerous Forbidden Technique: the Mafuba ("evil-sealing wave") technique will seal away an evil being indefinitely, but is said to cost the user's life. However, later uses of the technique in the story are survivable, merely draining a large amount of stamina. The story also parodies the trope, as the "denshi jar" used for the sealing is noticeably an electric rice cooker with a Paper Talisman attached.
    • Piccolo starts as a Sealed Evil in a Can, released by a hapless Emperor Pilaf, and quickly becomes the main villain of his devoted story arc. On being freed, he immediately sends his minions to kill every martial artist worldwide who might know the technique, to avert being captured again. Nevertheless, both Master Roshi and Tenshinhan use the technique against Piccolo, but both fail and the former dies as a result. Ultimately Piccolo is defeated by sheer strength at the hands of Goku.
    • In the 23rd World Martial Arts Tournament, Kami attempts to use the Mafuba against Piccolo Jr., who uses a "reverse Mafuba" in response. Being the stronger of the two, Piccolo Jr. wins the resulting Beam-O-War and captures Kami in a bottle. Goku manages to retrieve the bottle and free Kami. No one dies as a result of using the technique.
    • In Dragon Ball Super, the Mafuba is used to temporarily seal Zamasu, whose Complete Immortality makes him otherwise impossible to defeat, but thanks to a problem with the vessel, he escapes shortly after. Roshi later uses the technique in the Tournament of Power, using it to eliminate one opponent, and nearly succeeds with two others, but is prevented from completing the seal both times.
  • From EDENS ZERO, Creed's Ether Lock allows him to imprison people in energy cages which then shrink to the size of a matchbox, allowing him and Victory to carry the prisoner away easily.
  • Rossweise from High School DD is an expert at Sealing Magic from studying it to find a way to seal the 666. She can use it in combat to seal her enemies with powerful magic seals. Her sealing barrier is effective even against Armaros, the Grigori anti-magic specialist, if she has enough time to prepare it.
  • From Jujutsu Kaisen, the Prison Realm is a cube-shaped special-grade cursed object with a barrier able to absolutely seal anything inside a Pocket Dimension within it. Geto seals Gojo in the Prison Realm at the beginning of the Shibuya Incident, with him unable to be freed unless a cursed tool/technique that nullifies other cursed techniques is used.
  • In Lyrical Nanoha, Sealing is a basic Midchildan spell that renders magical constructs of all kinds inert and safe to handle. It sees most use in the original Magical Girl Lyrical Nanoha series, which revolves around the protagonist's search for corrupting magical artifacts. It also returns in a much darker usage at the end of Magical Girl Lyrical Nanoha A's, where it is used in the final episode to seal Reinforce — a benevolent and sympathetic magical construct tied to the planet-destroying Book of Darkness, — effectively killing her. In fact, the Magical Girl Lyrical Nanoha A's Portable Alternate Timeline gets spun off at exactly that moment because the protagonists refuse to cast the spell at her on moral grounds.
  • Fūinjutsu in Naruto is a brand of jutsu that can be used to seal objects, living beings, chakra, or a wide variety of other things within another object. Some notable examples include the sealing techniques that seal Tailed Beasts within Jinchūriki (as was the case with Kurama and Naruto), the Dead Demon Consuming Sealnote , or the Six Paths Chibaku Tensei (which was used to seal away the Ten Tails's chakra deprived body within the spherical prison that would become the moon). The titular character's clan, the Uzumaki Clan, were well known for their use of Fūinjutsu.
  • Nagi Springfield from Negima! Magister Negi Magi uses the binding curse Infernus Scholasticus to seal away the vampire Evangeline's powers and bind her to Mahora Academy.

    Comic Books 
  • One issue of Iron Man has him battle Doctor Doom, and both combatants get plunged into the past via Doom's Time Cube into the days of Camelot.

  • Turning Red: Any female descendant of Sun Yee can seal their red panda spirit into a talisman involving a ritual where they cross over into the astral plane. It can only be performed on a red moon (lunar eclipse). Even so, the talisman is a physical object that can be broken, which will result in their supernatural beast escaping. If they do accidentally/purposely break that Soul Jar, they can always perform the ritual again during the next red moon. However, if they fail to do so by then, the red panda spirit becomes one with them and can never be sealed away again.

  • Several spells in Dungeons & Dragons can be used to seal magic, creatures, and all manner of other things into objects for imprisonment or to plan a later release. Quite possibly the strangest is the magic jar spell, which the caster uses to seal their own soul away into the eponymous jar.

  • BIONICLE: A group of Toa can create a Toa Seal using their Elemental Powers. The Toa Metru were able to seal Makuta Teridax in the 2004 storyline. The only way to unlock such a Seal is to strike it with the same elements used to create it in the first place.

    • The Legend of Zelda: Skyward Sword: Link must seal The Imprisoned about three times over the course of the game using the sealing spike embedded in its head in tandem with Skyward Strikes from the Goddess/Master Sword, the seals getting more complex as the game goes on. Notably, the time between sealing gets shorter and shorter as The Imprisoned gathers more power and transforms, with The Old One noting the seals are just a temporary measure at best. By the time they finally manage to kill The Imprisoned, it's literally started to break out of the seal for a fourth time before it gets killed via falling floating island.
    • The Legend of Zelda: Breath of the Wild: Zelda herself acts as the seal, entrapping her and Calamity Ganon in Hyrule Castle for a century for Link to return and find a way to properly destroy the evil.

  • Azure Striker Gunvolt Series: Introduced in Azure Striker Gunvolt 3, Kirin has the Septima "Radiant Fetters", which allows her to seal all manner of supernatural powers, including the Septima of other Adepts. However, it's not always an instant sealing and she needs to beat down on particularly powerful foes before she can get it to work. Notably, this is the first time such a power has been the primary ability of a Septima, as previously similar abilities have been the result of secondary effects or due to clashing elemental powers.

  • The Treasure in Homestuck is a literal plot hole that can seal someone with Metatextual Attraction, overwriting their powers and imprisoning them in a nexus outside of canon.
