Binding Vow

A Binding Vow (縛り) is a pact made with jujutsu that creates conditions for themselves or agreements with others.

Overview
Binding vows are considered by all jujutsu users to be one of the essential tenants of jujutsu sorcery. Binding Vows are essentially contracts created through cursed energy which an individual can make with one's self or another person. The act of abiding by the rules and restrictions agreed upon in these contracts can result in a greater power or the achievement of a goal, but breaking a binding vow has uncanny repercussions.

Vows with Oneself
The quickest way for a sorceror to raise their level is through binding vows at the cost of risking own life. Self-imposed restrictions that are potentially risky to the user, such as willingly limiting the amount of cursed energy they can use for a period of time, can increase the output of the user's cursed energy and their cursed techniques.

As a product of negative emotions, cursed energy responds to the desires of its individual user. As a result, the user can increase the power of their cursed energy by establishing a self-imposed "Cursed Restriction" that creates riskier conditions to use their abilities. For example, by divulging one's cursed technique, it creates more risk for them, making their cursed energy swell in response to its user's resolve, and thus the power of that particular technique is boosted.

The penalty of breaking a binding vow with oneself is the loss of whatever was gained through the contract.

Known Vows
Showing One's Cards: A Binding Vow that increases the user's technique effectiveness in exchange for verbally divulging how their cursed technique functions.

Overtime: A Binding Vow used by Kento Nanami,which he willingly limits the amount of cursed energy he can access while on the clock working for Jujutsu High. Once his normal shift ends at 6pm and he begins working overtime, Nanami's cursed energy increases dramatically than he normally has without the vow.

Bird Strike vow: Mei Mei was able to force her crow into sacrificing its life in exchange for drastic increase in its cursed energy, capable of one-shotting a special grade curse spirit.

Sukuna's domain vow: By not having a barrier to allow an escape route, Sukuna can greatly increases his Malevolent Shrine's area up to approximately 200m radius.

Vows with Others
Contracts created between two or more individuals are bound by cursed energy. Both parties must agree to a particular set of conditions that benefit both parties. The penalty for breaking a Binding Vow with others is considered to be far greater than that of a self-imposed Binding Vow.

Known Vows
Yuji's Revival: When Yuji's body was deceased, Sukuna proposed a Binding Vow that would allow him to heal in exchange for allowing Sukuna to take control for one minute whenever he said a keyword. He also promised not to kill anyone during that time on the condition that Yuji would forget about the vow.

Yuji initially refused and demanded a fight to death in response. As a compromise, conditions were set by Sukuna. If Yuji wins then Sukuna will revive him without the Binding Vow. If Sukuna wins, then Yuji must agree to the Binding Vow and will lose all memory of it. Sukuna instantly defeated Yuji, forcing him into the vow.

Jujutsu High Mole: A contract between Mahito, Suguru Geto, and Kokichi Muta for Muta to act as a double agent for Mahito and Geto. Mahito and Geto agreed to heal Muta's body with Mahito's cursed technique in exchange for cooperation and information, on the condition that Mahito and Geto would not "lay a finger on anyone from Kyoto Jujutsu High."

It is alleged by Muta that this contract is broken, but Mahito rebuts this point by stating that Hanami actually was the one who hurt the students from the Kyoto College. Muta is transformed by Mahito's cursed technique after acting as a double agent for presumably some time, which brings the contract to an end, although it is unclear whether or not there was a breach.

Itadori's Executioner: In order to become Itadori's fake executioner, Yuta Okkotsu was forced into a Binding Vow with the jujutsu higherups where he was sworn to kill him. He then ends the Binding Vow when he does kill Itadori, but heals him with a reversed cursed technique in the very moment he does kill him, resurrecting him in a sense.
