During his coming-of-age celebration, Crest acquired a skill known as 'Gacha,' yet struggled to master its usage, leading to his exile into a treacherous forest teeming with beasts. In this unforgiving wilderness, Crest gradually grasped the potential of 'Gacha,' fueling his determination to endure, thrive, and reclaim his rightful place.
