Welp... shit just hit the fan.
I am coming up short to say much.... this escalated quickly, the confusion and first attack could be dealt with, but Cross being shot... that complicated things to put it mildly (hope they have hanten to heal him).
There is always an idiot with a gun.
So got my answer about Kaliyans... somewhat... they do have juryoku(loroluka), but if their corpses don't vanish when killed, they are fundamentally different from noroi.
I was curious how the isolate norois forming outside of Tokio... the answer is so simple I feel dumb... they used the same thing mechanic that forms them, the collective unconscious, then they directed the barriers system to isolate the city... considering all the leg work necessary, it still is an unstable circumstance.
And I think this explains why Mahito may be back... all that focused energy in one place, his conscience having stayed alive because of his special technique, it gave him the opportunity, but as it must be a delicate process, it took some decades for him to reform, or he was hiding, doubt he is so eager for his reunion with Yuji as he acted.
