Okasare Yuusha III: Yuusha nano ni, Binkan Sugiru Boku no Ochinchin...

The Empress suddenly assigned him to put down the strong monster, Kyubi (fox of the nine tails). Being a fresh exorcist, he tries hard to meet the expectation; however, dreadful yet sensual monster girls take advantage of his lack of experience and assault him sexually without a break! Can he defeat the powerful monsters to save the world? Or will he fail his mission and go to the heaven in ecstasy? (Source: VNDB, edited)
