Satoru Gojo is a child who is destined to become the strongest. He is 7 years old, still a boy. Although he is strong, he is still lonely. Everyone told him that he was the alpha, the one destined to be the strongest, but Satoru didn't want that. He wanted to run, play, and have fun like other kids. Laugh with them, go for walks, but all he could do was look at them through the window, listening to boring lessons. Satoru had had enough of this after all. While his fencing teacher was distracted, Satoru quickly ran out of the house, running far towards the sea. He stopped at a beautiful coastline, looking at the view. After walking a little further, he saw a small boy standing knee-deep in the sea, and around him were beautiful different fish. Satoru remembered this boy. The beloved youngest son of the Geto family, an omega, and also the one Satoru was engaged to by contract, for the sake of strengthening the two families.
