Four special-grade Curse Spirits!
The number of registered special-grade Curse Spirits at Tokyo Jujutsu High totals only sixteen, yet four have appeared simultaneously, none of which are ordinary special-grades!
At least, based on the intel provided, Tokyo Jujutsu High and various Curse Mage families have dispatched large forces to confront these special-grade Curse Spirits, including numerous first-grade Curse Mages, but all ultimately returned empty-handed.
Normally, even if a first-grade Curse Mage can't kill a special-grade Curse Spirit, they should be able to handle them, like Todo Aoi who could eradicate one special-grade and five first-grade Curse Spirits in one go, thus showing the caliber of a first-grade Curse Mage.
But facing these four highly intelligent special-grade Curse Spirits, even dispatching first-grade Curse Mages resulted in failures and heavy losses, nearly complete annihilation.
