Highlights
The Binding Vow is a powerful cursed technique that can be created by anyone who can manipulate cursed energy, and it cannot be broken by even the most powerful beings.
A Binding Vow can be made by an individual or with another person through verbal agreement, but once made, it is irrevocable and unchangeable.
The consequences of breaking a Binding Vow are severe, including the forfeiture of any benefits obtained through the vow and even physical harm, emphasizing the gravity of this technique.
Everyone in Jujutsu Kaisen possesses their own distinct cursed technique, but there are a few shared techniques that everyone can utilize, namely Domain Expansion and Reverse Cursed Technique. Similar to innate techniques, the strength and efficacy of these fundamental techniques vary depending on the user.
Nevertheless, there exists a specific cursed technique that proves effective against anyone, even the formidable King of Curses, Ryomen Sukuna. This technique is known as the Binding Vow, and the following information provides a comprehensive understanding of its nature.
What is A Binding Vow
A Binding Vow, in its simplest terms, is a contract made using cursed energy. Whether they are humans or cursed spirits, anyone knowledgeable in manipulating cursed energy can create a binding vow. It is not limited to being made between two individuals; one can also create a binding vow with oneself, as explained in the following section.
Unlike other types of contracts, a binding vow does not require specific incantations or unique manipulations of cursed energy. In fact, it is more similar to a verbal agreement, either with oneself or with another person. It is comparable to a gentlemen's agreement that is unbreakable. Once both parties agree on the details of the agreement, the binding vow is officially established. It is a simple process, which is why anyone with some ability to manipulate cursed energy can enter into a binding vow.
A Binding Vow With Oneself
Respecting a binding vow, whether made with oneself or others, is paramount. The length and complexity of such a vow depend on the specific contract. Therefore, it is crucial for all parties involved to comprehend every intricate detail of the agreement. Once a binding vow is made, it becomes irrevocable and cannot be altered. Additionally, attempting to evade the consequences of a binding vow will result in repercussions. This is precisely why even the most cunning individuals, like Sukuna and Pseudo-Geto, refrain from tampering with such commitments.The initial type of binding vow is a commitment made to oneself. While a binding vow between two individuals can be likened to an unbroken gentlemen's agreement, a binding vow to oneself is similar to making a promise to oneself but with significant consequences. Typically, a binding vow with oneself is undertaken with the aim of obtaining additional strength. However, this increased power is gained at the expense of something else.
The most common form of a one-person binding vow involves imposing self-imposed limitations on oneself or one's cursed techniques in order to gain a greater power. The specific limitations and resulting advantages vary from person to person.
In general, the more restrictive the limitations, the greater the additional power that can be obtained. In terms of consequences for breaking the binding vow, it is actually more forgiving compared to vows made with others. Those who break their own binding vow will simply lose the benefits they gained from it. For instance, if the vow provided a 10% increase in cursed energy output, breaking it would result in the loss of that 10% increase.
The most common form of a personal pact involves disclosing certain aspects of one's cursed technique. By intentionally revealing the effects of their cursed technique to their adversary, the power of their cursed energy output intensifies. Many jujutsu sorcerers adopt these straightforward personal pacts, including individuals like Aoi Todo, Nanami, and even Satoru Gojo to some extent.
Speaking of Nanami, he possesses an even more potent personal pact known as "Overtime." During regular working hours, Nanami can only tap into approximately 80-90% of his cursed energy. However, when he is required to work overtime, his cursed energy experiences a significant surge, reaching around 110-120% of its normal capacity.
A Binding Vow With Others
As previously mentioned, a binding vow between two individuals who possess cursed energy is similar to a verbal contract that requires compliance from all parties involved. A binding vow can even be established between a jujutsu sorcerer and a cursed spirit, as long as both parties are willing to form the contract. It is important to note that no party can forcibly impose a binding vow upon the other. Both individuals must willingly agree to enter into the vow for it to be valid.
The key aspect of forging a binding vow with another person lies in mutual interest. Both parties must benefit from the vow, ensuring that one side does not gain more advantages than the other. The definition of what constitutes fair terms varies depending on the individuals involved. Even if the terms of the contract may appear unbalanced to outsiders, as long as both parties consent to it, the binding vow will be activated.
A binding commitment between two individuals carries greater restrictions compared to a commitment made solely to oneself. Any intentional violation of this agreement will result in severe punishment. What adds to the danger is the uncertain aftermath, as even the parties involved in the creation of the binding vow are unaware of the possible consequences. These can range from physical harm to the loss of cursed energy, or even something entirely unforeseeable. This is why even Sukuna, a powerful entity, is obliged to honor a binding vow.
The series provides a couple of examples of binding vows between two individuals. One prominent instance involves Mahito and Mechamaru. Mahito agrees to share information about Jujutsu High with Mechamaru in exchange for using his Idle Transfiguration technique to cure Mechamaru's illness. Another significant binding vow occurs between Sukuna and Yuji Itadori. In return for bringing Yuji back to life, Sukuna gains the ability to fully possess Yuji's body for a minute whenever he utters the word "Enchain".
The Binding Vow technique may not be as flashy as Domain Expansion or Reversed Cursed Technique, but it is undoubtedly one of the most versatile techniques in the arsenal of every cursed energy user. Stream Jujutsu Kaisen on Crunchyroll.
