Back in the old Heian era, Domains used by Jujutsu Sorcerers were nowhere near as complex as they are now.
They skipped the elaborate process of building a sure-kill effect.
They were simple Domains centered on one thing alone: a guaranteed hit for the Cursed Technique.
Sukuna's [Malevolent Shrine] was the same.
It only looked especially monstrous because his technique was slashing. It had no special Domain effect beyond that.
Yorozu's Domain, [Threefold Affliction], was no different.
It, too, possessed only a sure-hit effect and nothing more.
Her technique was [Construction Technique].
By sheer coincidence, it was the same technique as Mai's.
But her understanding of it, and the structures she could create with it, far surpassed Mai's.
Because Yorozu did not have Koyanskaya of Light or Assassin at her side.
A white space.
Within it floated pillar-like bundles of nerves connected to what looked like the brains of insects.
Mai frowned the moment she saw the Domain.
It was disgusting.
