At the age of 12, Rosa received the "Baptism" that everyone must undergo—and because she was granted two skills that are normally impossible, she was sold as a slave!? "I'll never become a slave! I want to eat my fill every day and marry a wonderful man!" For the sake of her dream, she fled into the forest, where she became friends with three companions: Yuki, P, and Ho. Using the skills she received, Appraisal and Storage, she enjoys a survival life in the forest! ...Or so she thought. She ends up being attacked by goblins, rescued by knights, attending school...!?
