Looking for a more mature voice here! 

Example of the Japanese voice over: https://youtu.be/desYQeHMPZ8

Centorea "Cerea" Shianus is a centaur and the third girl to join the household, and allows only those people closest to her to call her by the nickname "Cerea" 

She is the stereotype of a Nordic person: she has yellow-blonde hair, pale blue eyes and a very large bust.

 Her "Horse part" appears to be the size of a small horse or a large pony, with an even, light chestnut coat, no mane and small hoofs. 

She is a herbivore (with a special fondness for carrots).

Like all centaurs, she is a warrior, living in a nearly bare, authentic Japanese room with her Western-type armor and weapons, pretty much in samurai style.

 Her demeanor and language is that of a medieval knight, and she has sworn herself to be Kimihito's servant through a series of misunderstandings after they crashed into each other by accident and later chased a motorcycle-riding purse snatcher together
