Mercie is a cheerful albeit childish girl with a very large soft spot for kitties. She has rescued hundreds of them, and with her brother and his girlfriend's help, was able to slowly turn their dying cafe into a fully revamped catfé where customers can pay to spend time with kittens and even adopt them.

She may not be the brightest, school wise, but what's admirable is her sheer dedication towards the things she loves- which are her friends, family and cats- and rarely does she give up on anything. Speaking of friends, Mercie loves to make new ones and tries to be there for them, always.
