Ok, I'm getting the hang of this now. I'll probably go back and edit Touko's so it has more close-ups of her nose and mouth too, and probably her basic face structure.
There's a lot to be said about Touya Everdeen. Unfortunately, most of it is relation to plot things, so my hands are tied. I can give you all a brief family history, like I should have done with Touko.
Touya is the result of a teenage pregnancy. His mother was eighteen when he was conceived, and his father ducked out. Her family pressured her to abort him, as having a child out of wedlock was heavily frowned upon. At the threat of being disowned, his mother left the region to live with her Uncle in Unova, where abortion was still illegal. There she had Touya and made a life for them, even though the rest of their family had turned their backs on her.
He grew up between his mom and Bianca's family. Bianca's father worked during the days, so he lacked a solid father figure growing up. However, he loved Bianca's family dearly and treasured having a sister. Since he was born after the cut-off date for kindergarten in October, his mother "Red-shirted" him so that he was in the same class as Bianca.
He met Cheren and Touko through Juniper's egg program a few years later and they became fast friends. The three were selected because of their parent's backgrounds: Cheren's father had experience with Pokemon in the police, Touko's father was a well-known trainer, and Touya's mother was a nurse at Accumula's PokeCenter.
M'kay that's about all I can tell you without getting into spoiler stuff. Hope you enjoyed!
