Another sinful natural charisma has been born in this world (laughs)!”Meanwhile, Iwata expressed her enthusiasm for performing the theme song: “The theme of each of our songs is a fairy tale, and the theme of this song is “Peter Pan”. The excitement and thrill of adventure is linked to this anime as well, and the song is full of a sense of speed.

As compensation for the mix-up, a goddess offers him the right to choose any skill he wishes for! Hoping for a peaceful and quiet life that has nothing to do with fighting or going into battle, he chooses a seemingly boring creation skill. However, it turns out “alchemy” is the most powerful skill that allows him to create everything from a holy sword to flying ships! This cheat skill he unexpectedly acquired turns him into a wealthy merchant and makes him undefeatable in battles! A heartwarming adventure story about (possibly) the most powerful alchemist in another world!
