Mamoru

is one of the three mascots of The Fire Defense Agency's 119.

Appearance
Mamoru is a dog, which was modified to take the appearance of and old man. It has a large head and a stubble, small, closed eyes and long black ears. Mamoru wears an attire with a horizontal stripe going along the sleeves and torso, as well as a vertical stripe going down the middle. It wears a large hat with the number 1 on it. It was noted by Arthur that Mamoru looks like an old geezer. He used to take the appearance of a dog, however, select members of The Fire Defense Agency complained about having all the mascots representing animals, so they modified Mamoru's face into that of it's current one. He is popular among young school girls.

Introduction arc
Mamoru appears alongside its fellow mascots — Race and Q — at the Fire Officer Newcomer Tournament.

Sentient Flame Human arc
The next day, Mamoru gets put into a tree by college kids and becomes stuck, but is rescued by Shinra. Mamoru tells the two officers that firefighters are receiving resentment from the local people due to the actions of a certain firefighter who was held responsible of murdering four innocent people, and that's why the college kids put him in a tree. He also informs them that that the final trial for the release of the convict, Setsuo Miyamoto, will be held today. Afterwards, the Shinra and Arthur help Mamoru to hand out balloons on a high street.
