The cult of “Snail’s Garden”, which once secretly exploited the hidden abilities of human beings, exists. However, one of the abilities born led to rebellion and the destruction of the church. Capabilities have also been scattered, and only rumors of huge property falling asleep at church sites have been whispered in the society behind them. Na Mei, who works as an intermediary and trades intelligence for people in the behind-the-scenes society, was caught in a crisis at the behind-the-scenes trading scene one day when Na Mei, who was present, met Kagurok, a man with superb arms. Two people, who were partnered by unexpected events, were born with abilities based on human experiments in the Snail Garden, and people in the back society were involved in the struggle around the church’s property and mystery.
