Alice, a younger sister who saw such a pitiful appearance, recommended a job change test to the guild of the kingdom, and Atlas was suddenly selected as the captain of the S rank party!

Atlas, who was having fun in the kingdom's number one guild, dismissed Captain Tony's plea-a different world fantasy that has made a big turnaround thanks to his sister, now opening!
