As they were examining the dogs they discovered the bears the Ōu Army was fighting against were of Akakabuto‘s bloodline. Seeing the number of dogs that are injured Hidetoshi knows they need help and more people from the village arrive to help and one by one the dogs were taken away for treatment. When Hidetoshi and Daisuke came near Unsai and Akame he sees the white kishu run off with Andy and the others to finish off the bears surprised at their numbers. Then, he sees Sirius, Shion and Rigel leave after the bears unsure what they are trying to do but Hidetoshi saw that their was some quarrel between the dogs and knew if they don’t pull it together they won’t win. As they try to treat Unsai the two realized they’ve ran out of medicine and had to take him back to the vet themselves. Daisuke begins to ask if Unsai will survive and what breed is he; all he could say is he’s not sure and that will depend on Unsai’s luck and will.

To his surprise, he sees that Daisuke has brought a hunting bow and tells hims that they’ve been outlawed and he’ll get arrested if he uses it. Now that he knows the bears can sense danger and seeing that Daisuke is too stubborn to move he and the hunters surround Daisuke to protect him and finish off the bears. Once the fight is over Hidetoshi counts that a total of 28 of Akakabuto’s Offspring is accounted for, amazed and surprised that so many bears would group together in the same place let alone not try to flee.

Then, when checking on Akame he discovers to see that the kishu’s eye injury wasn’t serious and he fully recovered his sight but Akame had to be treated with eye drops. He told Sasuke to keep his saliva off him and heard someone at the door, for the dogs that survived the fight Hidetoshi called their owners and one by one the pet dogs returned home.
