Appearance
Maron is a really small dog with a black and white color scheme,which is  mostly white and  black on his back over his head. He has big round black eyes and is always seen with his tongue out, he is described by few characters that he has a goofy yet cute face.

Personality
Maron often describes himself as a "Proud Boston Terrier". Maron has the utmost respect for Haruna, because she takes such good care of him. Maron sees himself as a freeloader, and feels that he must protect and comfort Haruna. Maron hates baths, however, he would never let Haruna know that. He describes his full name as Maron Sairenji, after his owners.

Maron believes that licking is a pet's greatest form of affection to its master, and takes great pride in his "skills" in licking, apparently not knowing its perverted appearance on a female human. In chapter 44, after Rito became a dog because of Lala's body-switching invention, Haruna ignorantly brought him home to take care of him, and Maron aggressively teaches him to lick Haruna, which Rito reluctantly forced himself to do before running away in shame.

Haruna Sairenji
His owner who he respects the most for always taking care of him, he describes her as having a mild and soft-hearted. He is aware of Haruna feelings towards Rito saying that she has love problems.

Akiho Sairenji
Akiho is his actual owner but due to always working, Haruna is always the one taking care of him.

Nana Aster Deviluke
As Nana is able to speak with animals, she and Maron occasionally speak to each other. She asked Maron to help console her friend, Mea, and Maron proceeded to aggressively lick all over her, possibly causing her to develop a fetish for being licked.
