As he prepares to take his college entrance exams, Youta and Ashura take a break and practice basketball.
After a while, Youta leaves the court to drink water, at that moment, a strange young woman approaches him and begins to claim that she is a goddess named Odin, and that she is above any other god in this land.
Youta believes that the girl is lost, but before he tells her that he will take her to a police station for help, she interrupts him and tells him that she does not need any help at all. Actually, he does not need to continue preparing for his exams, after all, the world will come to an end in 30 days.
As you might imagine, Youta is skeptical of such argument and returns to the court, where Ashura does not take long to make fun of Odin, who is actually named Hina.
Later, Youta decides to help Hina, but first he must go to the library, where Kyouko, a childhood friend, waits for him to continue studying. He is in love with the beautiful young woman, but he has never dared to mention it.
Along the way, Hina begins to surprise Youta, again and again, she makes a statement and it always turns out accurate. Even when they are eating ramen at the restaurant of an acquaintance of Youta, the girl is able to predict the results of horse racing in front of them.
Bit by bit, Youta becomes more intrigued by Hina and what she said before. And once she tells him that during the next few days, she will help him fulfill some of his wishes, Youta does not hesitate to ask her for an opportunity to go out with Kyouko.
She tells him that she can’t control anyone, but she can give him information so that he gets closer to her, in the end, the information seems correct, but, even so, she rejects him immediately, even before he can declare his love to her.
At the end of the day, Youta asks Hina if he can take her to her house, and she indicates him that she will live with him and his family, all he has to do is call home and ask his mother’s permission. He decides to call home, and unexpectedly, her mother accepts the young woman, and the adventure begins.
