Half an hour later, the Oya Family opened their gates and surrendered.
The death of Imagawa Yoshimoto was a huge blow to them. Plus, after getting tormented by New Wanjin for several years, they were exhausted, completely lacking any will to fight. Even if a couple of diehards wanted to "risk their lives" for a desperate struggle, nobody responded. In the end, the Oya Family hastily gathered their valuables and gold and silver, opened the city gates, and staked everything on Harano keeping his promise to spare their lives.
Harano had no intention of breaking his word. He wrote travel passes for the Oya Family's few dozen people and sent them packing. Then he left some of his own men to take over the castle, while he himself led the Wanjin Army to keep heading north.
