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.

Introduction arc
Mamoru appeared alongside his fellow mascots — Race and Q — at the Fire Officer Newcomer Tournament. Later, Mamoru gets stuck in a tree, but is rescued by Shinra, to whom it tells that the trial for the release of the convict, Setsuo Miyamoto, will be held. After that, Mamoru meets his fans, with Shinra and Arthur helping it with giving out balloons.
