Heavenly Restriction

"Heavenly Restriction" (Tenyo Jyubaku) (aka Heaven's Binding Curse) is a restriction of a sorcerer's ability in some capacity in exchange for increased ability in another capacity that was imposed upon them at birth (Chapter 38). It is similar to a contract in that it is an agreement to exchange something for another; however, unlike a contract, it is fixed upon the sorcerer in question at birth, meaning the person who it is subject to has no choice in the matter (Chapter 38).

Formation
It is unknown how exactly a Heavenly Restriction is placed upon someone. It is most commonly speculated among fans that it is something akin to a disability, in that the sorcerer is born with the restriction in place. A less popular fan theory is that that Heavenly Restriction is a type of contract imposed between parent, child, and a third being, but there is little evidence to support this theory.

Characters with Heavenly Restrictions

 * Kokichi Muta is an extreme example of a Heavenly Restriction. He was born without his right arm and lower part of his legs, cannot withstand sunshine or moonlight without sunburn, and experiences extreme chronic pain which he describes as feeling like every pore in his body feels like its being stabbed constantly (Chapter 38). In exchange for this, Kokichi has vast amounts of cursed energy that he uses to control innumerable puppets of various different shapes and sizes (chapter 38).


 * Toji Zen'in is thought to have been subjected to a Heavenly Restriction where his ability to use or create cursed energy was sacrificed in exchange for unrivaled physical ability (Chapter 77).


 * Maki Zen'in is similarly thought to have been subjected to a Heavenly Restriction of a lesser extent, where her ability to control and manipulate cursed energy and its flow in her body was restricted to that of a civilian, in exchange for physical prowess (Chapter 42).
