Ash came back to Alola after his journeys, he missed them so much, even though he also misses back at home in the Kanto region, he misses everyone in Alola aswell. Little did he know that his childhood friend and rival from the Kanto region came to the Alola region aswell. Professor Kukui meets him and finds out that he's training to be a pokemon professor/researcher and asks if he wanted to help him teaching some of his students, he accepted. I wonder what happens next? Who's the person that came to the Alola region? Who is Ash's childhood friend and rival? Who did Professor Kukui meet? Why did the strange person even accepted to help Professor Kukui to teach his students? Well its time to read to find out!! DISCLAIMER: I do not own ANY of the Pokemon characters, i only own the plot of this story. (i just remembered that After Sun and Moon, he actually went back to Pallet Town, having journeys with Goh ;-; So just pretend that Ash's journey was actually going anywhere else like the Hoenn region and the Kalos region ;-;)
