Nah, I just wanted to get your attention. but from what I've heard, getting an S rank chao IS a bit hard. I just wanted to know how to get one since I'm not entirely relying on the information I've heard thus far.

It's a simple matter of inbreeding your best ranked chao until you finally get to the coveted all S status. Remember that you can raise one stat one rank during primary evolution, allowing you to turn A ranks into S ranks and so on. I recommend buying chao at the Black Market (blue eggs are my personal preference, they're cheap and they look better than most other colors, but any color works as long as you can afford it) until you have Chao that collectively have an S or at least an A in every stat. That means five starter chao, although if you're lucky you can get one with multiple good stats and reduce your starting group to three or four. Then breed the best of them together, using reset if the egg you get isn't better than either of the parents it came from.
