Please read my full review so some of your questions will be answered. Thank you. If you don't then I'll say it here. The FIRST THREE girls, join the MC's harem quickly, yes, after that. The rest will join slowly, however, their development does not end there. This is also not a self-insert, even though I have rewritten Chapter 1 to try to be the same quality as the rest, there will still be plot holes and mistakes as THIS WAS ORIGINALLY WRITTEN BACK IN 2020 WITHOUT RESEARCH. However, with the rewrite, I hope to have corrected the majority of mistakes. Peace.
Alright you bunch of incels, listen up. I've seen a increase of brain-dead comments lately so I'm gonna say it straight. Since 90% are unintelligent monkey's. This is a story that's going to be told. If you're looking to self-insert yourself into the MC then leave. He won't bang things on the spot or killing random people cause uwu they didn't agree with me. If you want to read incel type novels like that, there's plenty of others on this site. Seeing as how the author won't regulate his reviews or comment section cause he's lazy. I'll do it, if he deletes this then good on him. He does things that seems weird or 'Why can't he do this or that since he's an Outer God'?, Ever heard of story telling? It's to make them interesting, to add drama, to add suspense, it's to tell a story. Reading perfect protagonist becomes stale over time, and you get triggered since you can't self-insert.
I'm a bit disappointed that you didn't bring Rias into the Harem, because Akeno and Rias are one complete package in the DxD harem. If you set the time before Akeno is reincarnated, it might make sense and I accept it. But here Akeno has been reincarnated by Rias, if you want the Queen of Rias Peerage. then better get the King too (Rias)
