Amongst the undine companies, it's a tradition to keep a blue-eyed cat (breed is not a problem here) as mascot for good luck.

President Aria is the Aria Company's mascot, a male Aqua breed feline (common trait are bigger than Earth breed and human-level intelligence). He is smart enough to understand human speech. President Aria was a stray cat before being taken in by Grandma twenty years ago and has been the company's mascot ever since.

He really loves to eat - coupled with Alicia and Akari doting on him - making him really chubby.

He has a crush on President Hime and is mortally afraid of President Maa and her tendency to latch her jaw on to his sizable stomach.
