Yveltal and Yoshito Igarashi

This is Yoshito Igarashi. He is a 9 year old boy who lives in kalos and never got use to fit in with other humans and they're other Pokemon.
2 years ago, he was walking in the woods one day with his Zorua and then encountered the legendary Pokemon Yveltal .
Yoshito was scared and hid behind a tree. But Yveltal looked at him and wasn't harming him at all. Yoshito slowly walked to Yveltal
and started petting yveltal's head. Yveltal liked being petted. Till then, Yoshito felt a strange dark aura around Yveltal. Even his Zorua
felt the dark aura. 
Yoshito: You feel lonely. I won't let you be lonely anymore.

So now Yoshito has this strong connection with Yveltal. Yveltal flew off and Yoshito talks to nobody except his parents, and Dark and flying type 
Pokemon. Those two years now, he has a smart additude and will only protcet those Dark and flying type Pokemon. His dream is to also own
his very own Dark type gym. And maybe in the future, Yveltal might want to enjoy the team.

P.S: The reason why I gave him a Japanese name is because it just sounds cool.
I mean in Kalos, its based off of France so...yeah many people were thinking, he should have more of a French name.
