Ah Man quickly wrote a letter to Harano, informing him of her plans and asking for support.
Harano didn't object; previously, he'd been misled by modern information and really thought of the Ainu as a single "ethnicity", but once he actually dealt with them, he realized that wasn't the case at all—just getting these tribes to form a loose alliance was hard enough, and getting them to go to war together was even harder.
Just by their current loose combination, at most they could hold back the expansion of the Lizi Family, maybe only slow it down—they couldn't possibly drive them out.
He thought it over for a while and agreed with Ah Man's judgment, telling her just to send people over; he would certainly make the preparations here. After sending the letter, he went back to raking in money.
