holy cow, this gotta be the most beautiful fanart of chris lightfellow I've seen.

and oh, who's the other chick?

I was wondering that myself. She doesn't look like any of the 108 stars from that game. Maybe she's supposed to be the Flame Champion's girl (I forget her name) when she was young?

I just checked the artist's gallery, it seems like chris and balsa are his favorite ones to draw, and so I think the other chick is Balsa of serei no morobito.

Yeah, that definitely looks like the same way he draws Balsa in his other pictures. I'm going to go ahead and tag it as such.
