Kaguro

Kaguro is the mate of Miaosora and the father of Iuka and Kayla. He lives in Osaka as a stray dog in the alleyways. When he comes to the forest to visit Miaosora, at the same spot where she gave birth to Iuka and Kayla, he sees her with Weed and Kagetora, but the puppies are missing. He looks under a fallen tree, but Iuka and Kayla are still out of sight. He thinks they might be in a tunnel or barrow then complains about how adventerous they are. He eventually finds Iuka swimming in a swamp and he asks her where Kayla is. Iuka cries in grief and says Kayla suffocated while trying to climb out of a tunnel, upsetting Kaguro.

Kaguro returns to Osaka in the next chapter and because of that, he doesn't get to see Miaosora die from bloodloss in the battle against the bible-thumpers.
