The Day I Became a God opens with Hina Satou, a peculiar girl in a flashy outfit who calmly declares that she is the Norse god Odin. Her claim would be easy to dismiss if not for the fact that Hina possesses genuine precognitive powers, and she uses them to warn Youta Narukami, a teenager already burdened by his own worries, that a catastrophic event is drawing near and could end the world. Youta is skeptical at first, but Hina’s certainty, her strange behavior, and the mystery surrounding her abilities make it impossible to ignore her warning for long.
As Youta is pulled into Hina’s orbit, the story balances the tension of a looming countdown with a quieter, more intimate look at the people around them. The heart of The Day I Became a God is the bond that forms between Hina, Youta, and the friends who gather at their side. Hina may insist that she is a god, but she is still a child who wants to experience everything life has to offer. With only 30 days left, they try to make each one count through small adventures, shared moments, and memories they can carry with them before time runs out.
