Mukku

Mukku is a pet dog in Ou. Accidentally, he overhears a conversation when Daisuke comes to pet him. He understands that the humans will blow up Gajou and he runs to the mountains to tell Weed whom the strays dogs has told him about.. He has never met him and therefore when he asks Kamakiri where he is, Mukku is beaten up. Luckily, Weed was nearby and he saves him. Mukku delivers his message and goes back home. At his home, he meets Gin who is searching for Mukku’s father, Bingo, who used to be a soldier of Ou. Mukku first mistakes Gin for Weed, but when he realises the mistake, he quickly tells Gin of what has happened. He is then invited by Gin to join his army and overthrow Hougen, an invitation which Mukku gladly accepts. (source: Gingasite.net)
