Puppy, Walk into Tomorrow! (Koinu yo Ashita he Ayume!- ( 子犬よ明日へ歩め!)

Kazarin killed a mother dog when testing her soon-to-be-beast-fighter wolf, Garus. The puppy who lost his mother was then kept by Daijirou. Kenichi didn't like his brother keeping a pet dog. When Voltes was fighting Garus, the puppy recognized the beast fighter as the former wolf who killed his mother.
