Overall, the writing quality is good, and I didn't come across any noticeable mistakes. The story development is great, and the pace is well balanced. There is a potential for further improvement and growth. The main character (MC) is likable, and the interactions between the MC and their future harem are cute. The world background has enough details to provide a solid foundation. Regarding the updating stability, I would give it a 5-star rating for now. In terms of evaluation, the story is fantastic and well balanced, showing a lot of potential. However, I found the chapters to be too long. It would be better if they were shorter, perhaps around 1.5k to 2k words. Please note that I will provide a more detailed review once the story reaches 15 chapters.

mc name really bothers me since it's the same as Abaddon family's name it's like someone being named sitri bael or gremory bael.

I am not gonna say much, but I hate Mc’s personality. I know he is a devil and as such he should act like one, but sometimes it gets too annoying. He seems like a flat character to me right now compared to a round character. Hope this fic gets better overtime, when it does I will change my rating, no hate!

I mean, I can bash him pretty hard for not reading original Light novel. He probably just read a wiki, and that's all. Another cliche with aika. Eh, I just can't fathom what people find in her. Come on, we in a world of perverted girls that's more hotter than her by quite a lot. Even with all my hate to sona, mostly because of her simps(and to be honest, she is on the same character level with aika) ,but even she is better the aika. I just confused. But okay. It's still a good read. SURPRISINGLY. From you failed harem in rent a prostitute, I wasn't expecting you to have balls for an actual harem. You was just endlessly simping for you actress waifu. And in the latest chapter, kaguya. It's mind blowing that you can actually write a character with balls and make a harem. Unexpected development. But isn't unwelcomed.

the personality of the protagonist is insipid and without charisma, many of the facts that lead to a conflict are absurd, the personalities of the cast do not finish convincing (the character is not captured)

Mc has a horrible personality, has worked for nothing he has and is worse than riser when it comes to harassing females. Majority, if not basically all the chapters are filler, latest chapter is an example.

I thought at first that it reeked of fem ideologies but some comments gave me insight to the truth: MC is a simp and not only for Rias; he over-exert himself for several others. No problem with the quality of writing but if the premise can hype, the story dev is disapointing. He is depicted as carefree when in actual fact he appear to me unbothered and it's only by what doesn't concern his sins or his pursuit of idealised waifus. Unless MC truly fall in love he shouldn't bother to lower himself with his supposed carefree attitude and his self-proclamed comformism to devil customs. The social status of an heir coupled with his succes in rating games and his level of power should come with admiration and awe in devil society and if you add the enticing Bael P.O.D, he should be a dream marriage candidate of many if not every house. At 17 he should already have a contract marrige if not severals. Bluntly the story feel frustrating to me.

Trash young master attitude is all I can say about that protagonist

MC's personality is incredibly flat, Rias being the best peerage manager feels wrong since it looks like they still all have their tramas. I get them being willing to die for their king but that's just most peerages, We've seen Sona's peerage stand up to the MC for their king for example.
