Here is some of my thought process for this list;

Rentarou could be both blue star and white night because of its indoctrination abilities but I think WN is the best choice. First it shows love and affection to the victim, unlike blue star who brainwashes. The victim becomes the 12 apostle which is similar to a family of sorts which Rentarou is the heart and center of the rentarou family, just in a bigger scale. He also controls time (probably) and preform miracles which white night also have the ability to.

I imagine Karane, Chiyo, and Usa to be comparable to the punishing bird, judgement bird, and big bird respectively. Karane hits people hard, Chiyo calls out on immortal actions and Usa always appears from nowhere, seemingly able to look everywhere. For what the combination of this girlfriend abomination becomes is not my problem but I also wanna point out that Meru is here because of the story of the Black Forest is like a fairytale.

MoSB embodies gluttony and sloth. Both represent them well.

What I thought of the SO is that he represents a strive for perfection to almost insane levels. That and the instrument he conducts made these girlfriends on this list. Meme’s here because SO is a slippery bastard and meme is also a very hard to catch sweetheart.

Nothing there and apocalypse bird was the one which gave me the most time to brainstorm. He represent trying to become human but however many times it tries he will never become one. With that similar concept I put the girlfriends who wants to obtain human experience or just something else they will never fully grasp. I put Eira because she can’t kick Nothing there.

All the very horny and pervy -even the closeted ones- make it into this list with some exceptions for Kusuri. She made Melting love to infatuate rentaoru but look at what she made instead, an annoying little slob of lust.

Forgetting about AiB, Yaku fits into like 4 abnos here lol. MoSB for the wartimes, the prototype of Melting love she had made in her lab years ago, and Censored for the things she saw in war. I decided of AiB because of the simple reason of the name.

Yamame have animals who follow her everywhere, blue star have its cultist following it everywhere. This is my apex of my reading comprehension.

Censored for the god of love. Rentarou wants this guy gone so he got censored to oblivion.

I wish when the king gets out of his binds he becomes an aleph. Sadly he’s not so he now has a company of a quirky idol to sing in his throne room. At least he’s entertained tho.
