"If you lose your virginity, I will destroy humanity." Before seventeen year-old high school shrine maiden appears the goddess of her shrine, Konohana Chiruhime, who demands that she join her as her wedded partner in the celestial world in accordance as Sakura promised as a child. Sakura, however, wants to stay on in the human world for the sake of Ichiki, the boy she likes, so she asks for a little more time - but when Chiruhime sees Ippuu kissing Sakura, she flies into a rage and breaks open the doors of the underworld, allowing gods of misfortune and illness to rampage freely in Shibuya! If Sakura agrees to go with Chiruhime, she will never be able to return to the human world; if she stays with Ichiki, innocents will continue being killed. What should she do...?
