Eros

Eros is one of the neutral divinities in the Monster Girl Encyclopedia world who is neither explicitly pro- or anti-monster. As the God of Love, Eros grants blessings to both human and monster lovers. Although naturally in the era of the current Demon Lord, the Order views Eros' human devotees with a little suspicion, she seems to mostly embody the virtues of classical, romantic, chivalrous love, as opposed to the crazed rape and hedonistic debauchery of the succubi, so her worship remains broadly accepted by the Chief God's church. Nevertheless, Eros inevitably has many monster followers. While one might be blessed with eternal love or even be rewarded with an angelic partner for good deed's in Eros' name, she can be wrathful if crossed: adulterous followers are likely to be cursed so they can never be loved again.

Monster related religions / gods (Fallen Maidens, p62)
In this world the most well known god is the “Chief God”, who is regarded as the creator god. Most humans are zealous followers of the Chief God, but because her doctrine is hostile towards monsters, of course there are almost no monsters who have faith in the Chief God. However, the Chief God isn't the only being that is called a god. There are various gods under the Chief God, and since they're not monolithic, they're not necessarily hostile towards the monsters. The neutral “God of Fighting, Ares” and “Goddess of Love, Eros” even have monster adherents. Also, these gods are said to grant blessings and protection to those who have faith in them, even monsters. In addition, many of the gods related to art and recreation are also regarded as neutral.

Quite a few of the gods have even taken the Demon Lord’s side. There's the previously mentioned “Fallen God”, and the “God of the Sea, Poseidon” who is worshiped by all those who live in the sea, etc. These gods also have an extremely high number of monster adherents.

Eros, God of Love (Fallen Maidens, p67)
A mid rank god who governs love. She is a god who views the love that living things direct towards other living things as beautiful, and blesses couples of the opposite sex that are in love with eternal love. But on the other hand, she's extremely strict about betrayal and other things that destroy love. It is said that if one of her adherents performs infidelity, etc. not only will they lose her protection on the spot, they'll suffer her divine wrath and become unable to be loved by anyone for eternity. It seems she is very empathetic towards the monsters who are overflowing with love for human men, and it is said that she even actively grants them her protection.

It is said that in the spaces where her devotees spend time with the opposite sex, there is always a sweet atmosphere, and the bonds of love that her devotees share with their lovers of the opposite sex can never be broken. The monsters are granted even greater blessings. As for monster devotees, depending on the potency of their love, the pleasure they give to their partner during sex, and the pleasure they receive from their partner become stronger, and sweeter, thus enabling them to express their love more strongly. Because of this doctrine and blessing, lately the number of monsters becoming her devotees is said to have skyrocketed.

Also, there are times when she dispatches her subordinates to men who perform good deeds. Her angel subordinates are all extremely beautiful physically and spiritually, and they strongly desire to love human men. Their mission is to continue showering men who've accumulated good deeds with love as their wives until they die. One would think this behavior is close to that of the monsters, but no matter what, it's regarded as “a way of expressing appreciation for those who have done good deeds.” The Order views it with suspicion, but it isn't treated as heresy or blasphemy.
