that exact same yama should able to be able to be recruited in the guild now. go recruit him.You need him for his high amount of hp and attack. Then put him in his own union for now. Also while your at the guild,talk to the person behind the counter and it should be a recruit leader option go into that and recruit the two on the list. Then put these two into Rushes union. If u need more clarification on what i just said let me know. Or if u completed these steps tell me so i can tell u my battle strategy.
