A suicidal kid gets a second chance, then discovers the price of living is competing to become god. The show means what it says about desperation and survival: these aren't metaphors, they're the actual weight pressing down on Mirai's chest every episode. It asks whether someone broken enough to want death is the person most qualified to save everyone else, then makes you sit with that question instead of answering it.

After losing his family in an explosion and suffering abuse from the relatives who took him in, Mirai Kakehashi reaches the end of his will to live and leaps from a cliff. Instead of dying, he meets Nasse, a winged being who says she is his guardian angel. She gives him two special abilities and persuades him to keep living. The freedom he tastes comes at a price: Mirai is thrown into a contest against 12 other chosen people, with 999 days to decide which of them becomes the next god. The once hopeless boy now resolves to do whatever it takes to protect his slim chance at happiness. Adapted from the manga by Ooba Tsugumi and Obata Takeshi, the series is a supernatural psychological drama with mystery and romance.
