"Since we are going to make a move against Lord Hemitrygon, it is better sooner than later."
"On the east coast of Oguri Island, near the Hemitrygon Shrine situated within the mountain forest, I noticed that during these few days of the sacrificial offering's presence on the island, Lord Hemitrygon will intermittently appear at that location in the dead of night, concealing his aura."
Hachisaku-sama divulged the critical information she had.
That was the possible time and location of Lord Hemitrygon's appearance.
She suggested that for the following days—tomorrow, the day after, and the days to come—Kamiyagawa should lie in ambush near the east coast of Oguri Island at night, waiting for Hemitrygon to show himself.
As for Hachisaku-sama herself, she would rest as much as possible, ensuring her combat strength.
And then, rush to the battlefield at the first sign of Lord Hemitrygon's appearance to provide support.
