Muu is one of supporting characters of Ginga Densetsu Weed: Orion & Ginga: The Last Wars. He is brother of Shirozaru, Rara and adopted grandson of Akame.


He is a pure black Kishu Inu.



Ginga Densetsu Weed: Orion

He was born to Miya as a domestic dog, and because of the oath he had no permission to become Iga's ninja dog. When Akame is believed to have died in the Ōu volcano, he is free to leave with Shirozaru and Rara to Ōu.

The other one rescues Sasuke with Shirozaru and Rara when the Kamakiri boys attack him. The other is also involved in rescuing Bella. He and Rara take Bella to safety, and then he returns to the warriors.

Ginga: The Last Wars

He is at the beginning of the story on Mount Mie Akame with his brothers, Weed's children and a few other dogs.

Later, Akame runs to indicate that the Monsoon have attacked Ōu. The rest of the squadron immediately sets off. They are waiting for Yamabiko's packs in the Kyoto Mountains, but after two days they decide to leave before Ōu. Orion and Yamabiko's packs join later and arrive at Nagano to Unsai. The United Dog Army then heads towards Ōu.

As the troops stop in Kunim, Unsai orders four reconnaissance teams in all major directions of the Futago Pass. Unsai assigns Muu and his brothers to the West as the fourth group, and the rest apparently acts as its leader.

At night, the rest of the group meets Cross, Maru and Sunny, who are staying at Daisuke's house. They tell Cross, among other things, the intelligence teams heading to the Futago Pass, and they themselves get information from Cross. The brothers eat the dog food offered by Daisuke and are then leaving, but suddenly Bob appears on the rock. Cross tries to persuade him to come down, but Bob escapes. Cross commands Muu, Shirozaru and Rara to Bob, but also tells them not to be too fierce about this.
