The harem will be decided from this list, but if you have suggestions please say which ones. If you want someone give the character a 'like' or comment on the character. It is also possible for simple one-night stands for those not mentioned, such as Yoruichi, who always seemed to me to be more on the type that would like to just have sex for fun and not because of a relationship.

And this is the current Affection Points and Heroine Summaries:

[Akeno Himejima: 'Sadomasochist Queen']

[Relationship Status: Interested in a possible new toy]

[Affection Points (10/100)]

[Heroine Summary: the only child of Shuri Himejima, a Shinto priestess and Baraqiel, a Fallen Angel and one of the leaders of the Fallen Angel organization, Grigori. As a child, Akeno was close to her mother as her father was mostly away on missions. Her perspective on love is marked by what she saw during the time with her parents (they never really closed the door), which led her into sadomasochism. Due to her respect regarding her mother she learned to become a sadist in time, trying her best to imitate her mother, even using the same haircut and manner of speech, but deep down she is still a masochist by nature and gets more excited when getting hit than when hitting others. She fell into despair when she witnessed her mother's death, blaming Baraqiel for not being able to protect her. Thus she searches for someone who won't leave her, but also being able to deal with her severe 'daddy issues'. She sees your domineering act and the aura you emitted as signs of a true dom, something she is curious about.]


[Ruruko Nimura: 'Mischievous Kohai']

[Relationship Status: Curious about her Senpai]

[Affection Points 50/100)]

[Heroine Summary: The only truly normal pawn of the heiress of the Sitri Clan, Ruruko Nimura suffers from lack of self-confidence. She works hard to try and stand out, but never quite manages to do so. She finds the prospect of figuring out this new mystery that has shown up in front of her quite interesting, and that you showed interest in her directly made it all the more so.]


[Koneko Toujou: 'White loli cat with kneesocks']

[Relationship Status: Respect your cooking skills]

[Affection Points (20/100)]

[Heroine Summary: Born as Shirone, Koneko is a young Nekomata who is part of a rare species among her kind, called the Nekoshou. She has considerable abandonment issues due to her and her sister leaving her behind after killing her master. If not for Rias Gremory she would have been executed like most of her race for her sister's sin. She carries great shame and blame due to this, as she believes she should have been able to see her sister 'losing control'. If she had, she could have tried to stop her sister and would stop more than forty thousand members of her race dying due to devil paranoia. She sees Ace as someone who makes the best food, gives great headpats and feels nice to stay close to. Her nekomata instincts are only starting to blossom so she can't yet differentiate properly the instinct for procreating with a strong male who can protect and provide for her and what proper love is.


[Isane Hyoudou: 'Sexy perverted cousin that wants to get in your pants']

[Relationship Status: Likes you for years now]

[Affection Points (72/100)]

[Heroine Summary: Since discovering her own sexuality, she has been attracted to you. She is a sexual being who knows little in the way of patience, and scoffs at the idea of taking things slowly. She wants you to create a harem so as to enjoy both sides of her sexuality, monogamy seems extremely boring for her. She houses the Boosted Gear inside herself and is unaware of the many dangers this will bring her.]


[Yuzu Kurosaki: 'Angelic cutiepie']

[Relationship Status: First crush and brother figure]

[Affection Points (43/100)]

[Heroine Summary: Yuzu Kurosaki, the oldest daughter of the Kurosaki residence, is a sweet girl. She cares deeply for others and likes taking care of those close to her more than most other things, her favorite pass time is making food for her family in the weekends (especially if Ace shows up as she can then show to him how good she is). Growing up close to two older brother figures in Ace and Ichigo she never could not help but compare others boys with them and find others lacking. Since hitting puberty she has developed a crush on Ace as the only male figure close by who she is close to and is not a member of her family. She is someone who got asked out 97 times due to how cute she is but refused every single one as none of them ever even bothered to know her before asking her on a date. She hates these superficial types the most, even if she does try and look for the good on people. However, do not doubt that beneath all that sweetness she is still a fierce girl who gets what she wants without hesitation.]


[Karin Kurosaki: 'Tomboy extraordinare']

[Relationship Status: boyish tsundere crush]

[Affection Points (38/100)]

[Heroine Summary: the youngest daughter of the kurosaki residence. She is a tomboy through and through. She never once used a dress out of her own volution and would spend more time playing soccer than dolls or talking about boys. She cares about her family but hates her father when he is being specially annoying (which, for her, is about 95% of the time). Growing up with her older brother and Ace she always know that Ace is a money grabber, he would get the chance to make any money, but despite not looking like it she appreciates it as it shows he is not some 'dumbass' who gets taken advantage off so easily. Since hitting puberty she developed a crush on Ace as he was the only male figure close to her family that she knew well enough and never judged her over her preferences, many times even helping her one way or another. She is a strong fierce girl with a tomboy attitude who does not back down from any challenge life sends her way.


[Mio Naruse (Gremory): 'Red Bombshell']

[Relationship Status: Trusts as bodyguard and protector]

[Affection Points (53/100)]

[Heroine Summary: Mio Gremory is the illegitimate daughter of Sirzechs Lucifer and a demi-goddess born from Hecate, the Greek Goddess of magic. Due to her heritage Mio was born with absurd magic energy levels and great talent, but exactly because of this and other reasons she has had her powers sealed and sent to live as a human in Earth. She lived there until recently when her existence and whereabouts were found out by the Old Satan Faction and subsequently had her guardians, who were like mother and father to her, die in front of her eyes. Thanks to saving her right on time and more she now sees you as someone she can trust and is her greatest pilar of support in this new crazy world she now has to live in.]


[Maria Kurono: 'Loli Succubus']

[Relationship Status: Interested in your body]

[Affection Points (12/100)]

[Heroine Summary: Maria Kurono is a member of the succubus race. Having grown up under a special institute due to various reasons she has only ever met her mother or the rest of her families a few times. Despite that she takes great pride in her family and heritage, refusing to be looked down upon due to it despite many high standing devils doing so for various reasons. As a succubus she is the type that loves pleasure and lust more than most things, but it is not like she would just spread her legs for anyone. She is interested in Ace's body due to his dominating aura born from the Conqueror's Haki.]


[Rias Gremory: 'Red princess']

[Relationship Status: emotionally unstable and desperately searching for a pillar]

[Affection Points (28/100)]

[Heroine Summary: The heir for the Gremory household Rias upbringing was at the same time easy and terrible. Due to her brother reaching heights unheard off amongst devils much expectation was put on Rias since young, expectations which she could not fulfill due in part to her own laziness but, most importantly, for how exagerated those expectations were. Due to how she could not fulfill those expectations no matter how much she tried she simply gave up on trying, not seeing a point to training when she could never be as great as people expected from her. Now her father want to force her into a marriage with the son of a friend of his, a son that carries similar ways of thinking to Rias' own father. Rias hates this very idea since she doesn't want to go through what her mother goes through nor wishes to marry someone who she doesn't love nor respects her, openly saying he would make her produce many kids for his own glory. With no help from her family or friends due to politics she is ready to do just about anything to get out of her marriage but her defeatist personality hampers her. She thinks that you may be able to help her be able to defeat this bleak future that is pressing down on her.]


[Sona Sitri: Water Princess]

[Relationship Status: intrigued and interested]

[Affection Points (55/100)]

[Heroine Summary: The heir for the Sitri household Sona respects intelligence above all else. This, however, faced several problems in the Underworld due to how in it might makes right. Unlike other devils Sona took great inspiration from human society and sees real democracy and equality as something that should be achieved for her race. Her dream if creating a school for all devils to learn about rating games and improve themselves play heavily on that dream. However, no one supports her in this wish in the Underworld, not even her sister who showers her with an unending amount of affection, but this did not deter her in her desire to follow through with her wish. She is fiercely independent, making it a point where, for someone to marry her, they must first beat her in chess and, if the male can do this, he would become her fiance. She is shocked that Ace, the money grabber who she thought was no more than a mercenary, managed to beat her in a game of chess which no one has done before and is also surprised by his ideas which she, as someone born in the Underworld, never really thought off. She also has an inferiority complex due to her body not developing nearly as great as her sister or her own friends.]
