Kyousei Ranbu: Itoshi no Kamisama wa Amaya ka ni Osu deshita

I, Hiri Yasaka, serve Minakata-sama, the "Guardian God of the Village," as a shrine maiden! Minakata-sama is always kind and wonderful, and even though I have a crush for him, just being by his side like this is enough to make me happy... That's what I thought, until today! It seems that Minakata-sama's power is weakening, and the only way to restore it is to have sex with me, the miko! Even though it was for the sake of Minakata-sama, as he kissed me and gently laid me down.... I couldn't stop my heart from pounding with excitement at the sight of his sweet face and his strong chest beneath his kimono. But then Minakata-sama made me an "unexpected proposal"...! This is the start of a slightly mysterious and heart-warming love story between a God x Miko! (Source: Kanon Comics, translated)
