Owari once again descended into chaos, so Harano had no choice but to temporarily give up exploring the Ise Mountains and return to New Wanjin to muster his army, in order to help Oda Nobunaga deal with the challenges from Saito Yoshitada and Oda Nobuhide.
There was really nothing he could do about it—he was still highly dependent on the trade routes controlled by the Oda Danjo Chonosuke family. Even though his ally Oda Nobunaga was a huge pain, constantly demanding him to join this battle or that, he still had to go. The truth was, only with New Wanjin in good shape could he keep exploring the Ise Mountains—without the power of New Wanjin and all these elite subordinates, he'd last maybe three days alone in the mountains before getting gored to death by a wild boar. So much for exploration.
