Generally speaking, whether they were Curse Users, Curse Sorcerers, or Cursed Spirits, all practitioners capable of deploying Domains would shape them into closed barriers.
This was to prevent anyone from leaving the Domain and escaping its range.
Only those within the Domain could receive a boost in power from its caster, and only within the Domain's range would their Cursed Techniques become attacks that were guaranteed to hit.
If people could simply leave a Domain at will, then that power would hold little meaning.
Thus, most Domains were closed, including Riezel's and Gojo Satoru's Infinite Void, as well as Mahito's earlier Self-Embodiment of Perfection. Once a Domain was deployed, it became extremely difficult for those inside to escape.
But Ryomen Sukuna's Demon Subjugation Kitchen Shrine was different.
He had deliberately shaped his Innate Domain into an open world that required no enclosure. By using the freedom to enter and exit after deploying the Domain as a binding vow, he had gained a far larger guaranteed-hit range.
His Cursed Technique was slashing attacks, so naturally, the larger the attack range, the better. Any living or nonliving thing that stepped into the Domain would instantly be sliced into fragments, so it did not matter whether others came or went.
As long as they entered, death was certain.
And if they wanted to leave, they would have to cross the enormous attack range gained through the binding vow in an instant.
Once such a Demon Subjugation Kitchen Shrine was deployed, it did not form a spherical barrier floating in the air like Infinite Void and Self-Embodiment of Perfection had earlier. Instead, it unfolded directly on the spot.
The blood-red sky, the reflections on the water, and the demonic, ghostly Buddhist shrine were all displayed openly in the outside world.
"Bang!"
At that instant,
