Adventurer Might lost his life while defeating an evil dragon. However, he was brought back to life by the blessing of a goddess who heard the ‘wishes’ of ‘the companions who saved the world together.’ Furthermore, due to Might’s own ‘wish,’ his class changed from ‘Thief’ to the ‘Sage’ he had always admired! When Might, who returned to Level 1 as compensation for changing his class, heads to the beginners’ guild, he finds ‘a group of girls in a beginner party’ arguing about something…? The second-life adventurer’s harem fantasy begins!
