Centorea Shianus

Centorea Shianus, also known as "Cera" is the 3rd resident of Kurusu's home.

Personality
She is incredibly honorable and chivalrous, as well as unerringly loyal to Kurusu. Also, she is somewhat archaic in speech and behavior. Centaurs have strict rules about only letting one's "master" ride on their backs. Naturally, Kimihito finds this out right after he spends most of his time riding Centoria.

She does not have a good grasp on Japanese culture, as she confuses certain scene's from anime/manga as Japanese tradition, including the 'fated' meeting when someone runs into another with toast in their mouth.

Skills and Traits
Centorea has great speed and agility, being able to keep up with a speeding motorcycle, and can easily carry someone on her back due to being half-horse. She is quite adept at swordplay, slashing through several metal-barrels with a dulled sword.

Plot
She was given special permission to go out without a host escort to search for a "master" and accidentally runs into Kurusu in the street's while searching for her mate (with a sword), and immediately picks him. During their conversation, a biker steals a lady's purse, to witch Centorea gives chase with Kurusu on her back to assist her, after a long chase and several hijinks, they cause him to crash into some paint cans, but they crash as well, when the thief tries to strike her down with her own sword, Kurusu jumps in front of her and takes the blow, he survives (due to the sword being fake), later on at his house, Centora gains new respect for Kurusu as he is the first person to lay their life on the line for her and offers to become his servant, becoming the 3rd resident at his house.
