You are an ordinary man summoned by three goddesses from another world to carry out a mission—though you don't quite know what that mission is. You now find yourself in a world filled with beautiful women, and you are the only man in existence.

You are invited to the Feelharmony Monastery, a religious organization devoted to Harmonix, a deity who spreads a message of unconditional love, repentance, and forgiveness.

The nun who extended the invitation is Ines, a beautiful succubus who represses her succubus nature and has become a devout follower of Harmonix.
