Interminable Restriction

**Interminable Restriction** (無間 呪縛, *Muken Jubaku*) is a type of cursed restriction invented by Mimei Futamigawa that he developed to serve as a new form of accessing and manipulating cursed energy. It consists of manipulating the soul to generate high amounts of cursed energy through the creation of a near-death experience, only to then immediately bind and seal the energy that was created, which can be released when the user wants it in order to vastly increase the user’s abilities. In theory, this technique could even be used to turn non-sorcerers into sorcerers. Mimei developed this technique in order to no longer be dependent on Master Tengen’s barriers for the stabilization and amplification of jujutsu, in his vision to make jujutsu sorcerers self-sufficient and independent of the will of the higher-ups.

Once Jujutsu Headquarters got word of this technique, it was immediately branded as forbidden and an execution order was given for Mimei and his compagnion, Aoba Hamorebi, who had already underwent it. Currently the technique rests exclusive to Mimei and his group, and Jujutsu Headquarters considers it a top priority that they should be destroyed along with all knowledge of it.

Though innovative, Interminable Restriction is not a unique technique but falls into the lineage of a branch of jujutsu sorcery that seeks to harness and control the cursed energy of death. According to Seimei Abe, these kinds of techniques have always been forbidden by Jujutsu Headquarters, because while they can be used to amplify one's power, they are ultimately harmful to jujutu sorcerers and the world because they move the user away from their True Essence and cause more cursed spirits to be created.

## Functioning

Mimei started researching Heavenly Restrictions during his second year as a Tokyo Jujutsu High student, in order to better understand the origins of their lifelong effects. He theorized that at the instant of being born, a huge amount of cursed energy was produced in the brain, in the same way that it is generated in the moment before death, and that this cursed energy served as the basis for a Heavenly Restriction to be created. For those who do not develop such a restriction, this energy diffuses and escapes, possibly creating a cursed spirit. Mimei then started looking for a way to recreate this process - generating massive amounts of cursed energy through a specific event, only to then immediately seal it behind a Binding Vow, that could then be released for a massive increase in power when the user needs it. This could allow jujutsu sorcerers to grow stronger “without giving up anything they already possessed”, independently of the Pure Barriers of Master Tengen that are traditionally used to stabilize cursed techniques, and possibly even turn ordinary humans into jujutsu sorcerers.

Currently, the only way to apply an Interminable Restriction is to create an environment that causes immense physical and mental trauma that brings the subject as close as possible to death, causing their brain to produce enormous amounts of cursed energy. An experienced user of Cursed Restriction can then guide them into shaping that energy into a Binding Vow with themselves. Mimei is the only person that has the knowledge to guide others through this process, which requires a very specific ritual for it not to backfire disastrously. Mimei has also experimented with using the technique on himself, especially in the early stages of development, which he compared to “*doing surgery on your own appendix*”. The technique is still not yet perfected, however, and still carries many risks. Currently, only Mimei can only perform it with relative safety, and he has used it to empower both himself and his allies.

There are numerous risks associated with an Interminable Restriction. The traumatic event that is induced in order to trigger the generation of cursed energy can be too much for the target to bear, leading to lasting damage or even death. Additionally, it can lead to the growth of a vengeful cursed spirit within the target’s domain, that becomes stronger and more present over time if not treated correctly. The point of the ritual is to minimize these risks, but they cannot be eliminated completely. The power that is gained in return of the restriction can also not be used to suppress the consequences of the process itself.

* **Spontaneous Interminable Restriction** (自然 無間 呪縛, *Shizen Muken Jubaku*): In the event of a near-death situation, Mimei can rapidly apply an Interminable Restriction on the target using the energy that is released when faced with death. The risk of the person dying anyway due to the stress of controlling that much cursed energy is much more elevated, however, and it leads to the inevitable creation of a curse within the user’s domain. Mimei likens it to making a ‘deal with the devil’, because the user’s life is extended and power is increased, but in the long term they will have to deal with the cursed spirit growing inside them and taking over. Due to these downsides, he has only used it once: to save Aoba from dying after she was targeted by Nazar.

### Technique Release

**Interminable Restriction Release: Earth Womb** (無間 呪縛放 地蔵, *Mugen Jubakuhō: Jizō*): By releasing the binding that was placed on them, the user can access the massive amount of cursed energy that was being stored by the restriction. Moreover, the stressful process of Interminable Restriction mutates the soul of the user, causing them to gain access to new abilities they do not possess when the restriction is active. Releasing their Interminable Restriction can increase the user’s abilities up to 150%, often allowing them to turn the tide of battle in their favor.

**Interminable Restriction Second Release: Death Womb** (無間 呪縛二放 死蔵, *Mugen Jubakunihō: Shizō*): A second release that is accessible only to those who have had multiple Interminable Restrictions placed upon them. So far, it has only been observed in Aoba, as the result of the Spontaneous Interminable Restriction that Mimei placed on her. When she releases it, she gains immense power, enough to elevate her to the level of a special grade jujutsu sorcerer, but she also empowers the cursed spirit inhabiting her domain, leading to her having to fight a constant struggle for the control over her body while the technique is active.
