Ginga Nagareboshi Gin
The cubs and their mother were hiding from the rain in a cave, when Daisuke and Gin showed up. The bear mother attacked them to protect her cubs, but she was killed by Daisuke. The cubs then came out of the cave and Daisuke realized that the bear only wanted to protect her cubs.
Even though the cubs were Akakabuto's children, Daisuke wanted to let them go. However, John appeared and killed them without mercy. Gin tried to protect them, but he failed.
