Hannya did discuss with Kamiya, she believes Kamiya should avoid "dying" in Tokoyo.
Hannya's thoughts actually arose right after Kamiyagawa was promoted to Aragami, and grew stronger over time.
Kamiyagawa can be an "Immortal" in Tokoyo, relying on the Substitute Paper Person system intrinsic to "Strange Tales".
According to current understanding, the "Strange Tales" system is likely a method used by Old Takamagahara to guide and lead the Lord of Demons and Gods.
Of course, other possibilities cannot be ruled out, but "Strange Tales" could not have been created without reason.
If we assume, for the time being, that this system is a method of Old Takamagahara, then the Substitute Paper Person system also originates from Old Takamagahara.
This is where Hannya's concern lies.
It must be known that Old Takamagahara's deities have long since decayed.
