Twelve years ago Y/N L/N and Sun L/N were kidnapped. Shauna and Calem, their parents have been searching the worl for them until they made their way to the Alola region where three teens Gladion (17 yo) Lillie (15yo) and Hau (16yo) set off on a journey to save Y/N and Sun who are now 16 years old and have never seen the outside world. Traumatized they learn to start trusting others.
