Again, not my art, I'm just an editor.
The idea was Serena and Ash are travelling Kalos, and Calem is tagging a long to the next gym.
Serena introduces Ash to Calem, who is one of her rivals and he soon becomes Ash's rival as well.
Again NOT my art, I just used editing tools like PicMonkey and Pixler.
