A special grade Cursed spirit born in the heian era as a conglomerate of what was supposed to be 2 separate Cursed Spirits those being Giman and Enma Daiō.
Giman, is a vengeful Cursed spirit born from a sorcerer who was stabbed in the back and that sorcerer, after being reborn changed their name to Giman although their Cursed technique was lost and subsumed by Enma Daiō's Cursed technique in their fusion.
Enma Daiō is the disaster curse born of lies and possess the Cursed technique: Sekai no teian (world suggestion) which allows for certain "suggestions" that are forced upon the world. The more complex or destructive these "suggestions" are the greater Cursed energy is required for them to take effect.
Even with the Cursed energy limitations there is still a limit to these suggestions. It's user cannot "suggest" the Death of another since the death of another is less of a suggestion and more of a demand causing significant backlash upon its user and depending on the target of these "demands" the complete Erasure of the user from reality.
Things like demanding the destruction of an object, stopping the activation of a cursed technique, attempting to control a jujutsu sorcerer, changing a sorcerers biology or cursed energy reserves in any way also counts as a Demand.
Kyohi also has a unique body structure due to the imperfect fusion of two cursed spirits and therefore has two separate minds and two separate Cursed energy reserves.
The final and ultimate tool of this curse is the apex of jujutsu, its **Domain Expansion: Two-faced Reality**
The sure hit effect of Two-Faced Reality is the enabling of "Demands" without consequences making the inside of a domain complete and near instant death for anyone caught within it.
