The Lost Monster Hunter Returns

When ten-year-old Erling, the son of the renowned hunter Karl, is snatched away during a beast attack, a forbidden elixir wipes his memory and another boy takes his place. Under the name Viggo, he is worked as a mistreated thrall, while the impostor Gunnar is brought up as Karl's cherished successor. Eight years later, Viggo signs up for the Hunter Trials hoping to earn his freedom, never realizing that the father who has been searching for him all this time is competing right beside him.
