sunny boy books

I was 15 years old when Arceus threw me back in time to save the region of Hisui. I succeeded, but... I couldn''''t return for another two decades. Now I''''m finally strong enough. One last battle with the Creator themselves and I can go back home. I can see my family again. My friends from school. I won''''t be leaving much behind but I''''ll miss Akari. Though... what will I even do after I come back?
