Overview
- Binding vows in Jujutsu Kaisen function as enforced contracts reflecting mutual interests.
- There are two principal types of binding vows: those made with others and those made with oneself.
- The repercussions for breaching a binding vow with others can be severe, and potentially fatal.
The universe of Jujutsu Kaisen offers more than just eye-catching abilities like Innate Cursed Techniques or Domain Expansion. It is a complex realm filled with numerous tactics and abilities that skilled Jujutsu Sorcerers can wield. This includes defensive techniques such as barrier manipulation, offensive maneuvers involving Cursed Tools, Reverse Cursed Techniques, shikigami, and advanced fighting techniques like Black Flash.
This article delves into one such technique—binding vows—which focus on the restrictions imposed by curses. It’s a notable mechanism utilized throughout the series. In this discussion, we will clarify the essence of binding vows, illustrate examples of both types of binding vows, and detail the repercussions of breaking them.
Understanding Binding Vows

To comprehend binding vows, we must first define their nature and functionality. What exactly constitutes a binding vow, how is it activated, and how many variations exist?
The Concept of an Unbreakable Contract
Essentially, a binding vow is akin to a contractual agreement forged through jujutsu sorcery. When two parties engage in a binding vow, they negotiate their respective terms, which become effective upon mutual consent. The vow remains in force until both sides satisfy their obligations, and it cannot be prematurely dissolved until these conditions are met.
“A binding vow is established on mutual interests. It holds significant importance within the realm of Jujutsu.”
—Ryomen Sukuna, Chapter 11
Types of Binding Vows
Binding vows can be categorized into two types: those made with others and those made with oneself. The relationship established in a binding vow between individuals mirrors that of a conventional contract. Meanwhile, self-induced binding vows are particularly intriguing, as they often aim to enhance the user’s abilities or accomplish feats unattainable through standard methods.
Illustrations of Binding Vows

Now that we have a foundational grasp of binding vows, it’s time to explore some notable examples featured in the series. With various instances of binding vows, this section will highlight examples for both categories of this complex contract.
Self-Imposed Binding Vows





The primary objective of a self-imposed binding vow is to amplify the user’s cursed skills. This often involves imposing limitations or sacrifices to heighten certain aspects of the user’s capabilities. A common self-imposed binding vow is the strategic revelation of one’s abilities to opponents, which in turn strengthens those abilities.
For instance, Nanami exemplifies this with his Ratio Technique. He deliberately discloses his technique to adversaries, enhancing its effectiveness. Additionally, he establishes a further condition by restricting his normal power to 80-90% during standard hours, allowing him to reach 110-120% power during “Overtime.”
Mutual Binding Vows





Within the narrative, various reasons drive the establishment of binding vows between different characters. For instance, Ryomen Sukuna strikes a binding vow with Yuji, agreeing to revive him in exchange for controlling his body for a minute upon saying the word “Enchain.”Additionally, Mahito and Mechamaru enter into a transaction-based vow, where Mechamaru offers critical information in return for Mahito’s promise to restore his physical form.
Moreover, there are one-sided binding vows, such as the one imposed by the higher-ups of the Jujutsu World, compelling Yuta to kill Yuji. If Yuta fails to carry out this task, he faces death. Despite appearing significantly disadvantageous, this binding vow holds validity as long as Yuta consents to it, which he did.
Consequences of Breaking a Binding Vow

So, what transpires when a binding vow is broken? Are the consequences different if one party breaks the vow versus both, or if an individual fails their self-imposed commitment?
Consequences of Breaking a Self-Imposed Vow
It’s crucial to understand that breaching any form of binding vow results in repercussions. However, the penalties for failing a self-imposed binding vow are generally more lenient compared to those associated with mutual vows.
As previously mentioned, self-imposed binding vows are crafted to enhance a user’s cursed technique. According to Kenjaku, the typical outcome of violating a self-imposed vow is the loss of enhanced effects the user would have otherwise experienced.
Referring back to Nanami, if he chooses not to reveal his Ratio Technique, he simply foregoes the additional strength he would have gained by enlightening his opponent.
“A binding vow made with another person carries far greater weight than one imposed on oneself. If we choose to break the binding vow now, the type of retribution that may follow remains uncertain.”
—Kenjaku, Chapter 79
Consequences of Breaking a Mutual Vow
Conversely, breaking a mutual binding vow incurs significantly harsher penalties. The peril lies in the uncertainty surrounding the consequences for such breaches. The only certainty is that the punishment will be devastating.
This fear of the potential unknown price is why everyone regards binding vows seriously. Because with jujutsu sorcery, no one is eager to “mess around” and risk invoking a dreadful outcome. It’s conceivable that one could undergo a slow and excruciating transformation into a grotesque cursed spirit merely for breaching a vow.
For example, Kenjaku, who orchestrates many heinous events within the series, is known to avoid trifling with binding vows. This illustrates that every sorcerer and cursed spirit fundamentally respects the gravity of binding vows.
