The next morning I joined in questioning the hostage with Zanoba.
He's part of the royal family of the aforementioned North Country.
Whether or not they know the existence of Hitogami: No.
Whether or not there was a guy in their country who made a remark or claimed to foresee the future: No.
Then how did they perform the invasion collecting 5000 soldiers in such a short period of time?
They had been eyeing the Shirone kingdom for some time, working towards an invasion slowly.
