Urara, self-proclaimed Goddess of Matchmaking, appears before Hajime Kanbayashi with unwelcome news: his years of dabbling in love spells and charms—harmless individually, catastrophic in accumulation—have thrown the law of cause and effect out of alignment. The outcome: permanent solitude, unless he ties the knot within the year. Urara presents three candidates written into his destiny, each with a "destiny count" representing the romantic distance he needs to close: Nanami Nagumo, the prime minister's daughter, at 870 million; Yukari Suo, Japan's top detective, at 65,535; and Suzuna Akagi, an idol, at 15. The race is on.
