Ok establishing volume. I enjoyed the initial setup with a human from our world and with a player character in a game being sent forward to a world 200 years in the future from when their character is said to have died in lore. But then I felt like we didn't really get to witness Lufas do much of anything the rest of the way (besides build an RV motor home). Her greatest attacks were basically punches that left enemies on death's door step.
The narrative does like to throw out numbers, and while they do establish what powerful warriors are and what Lufas, an absurdly powerful person, is, I don't recall them establishing what an average person is. Either way, the numbers are just so ridiculous and the reasoning for them is all over the place (for instance, the main character makes a golem at one point, and somehow it has random stat gains for its shape and make-up that aren't at all even zero ending numbers). I did kind of like the idea that the devil king can lower the heroes' stats, which is making things a bit more even. Other characters we learn much more about their ability sets, for instance the fire based rainbow sheep monster Aries of the Heavenly Stars and the water based elf mage Megrez who leads the kingdom of Svel iirc.
Speaking of the heroes and the Heavenly Stars, the novel establishes some more numbers with them being made of 7 (4 living?) and 12 members respectively. It seems that the plot is going to mainly focus on Lufas re-establishing support from those Heavenly star monsters
World building is maybe just ok, but the myth building is pretty good. It was kind of fun how the wacky designs human players came up with have to have lore excuses (things like rainbow wings or jet black wings that would look out of place are in fact strange mutations or something). Visiting the library and seeing the way Lufas and the heroes battle was thought of after 200 years, it was interesting. Even the way some characters would turn on everything she established (joining up with demons) was intriguing, though that's as far as it went. I didn't feel like anything in this volume was that "fun" or "rewarding" as a reader, just neat. Probably the most intriguing element was Dina's ability sets and the reaction to her from other members of team Lufas, most not remembering her from the castle despite her claims to have been there the whole time. I'd guess she's in league with the demon king, or trying to overthrow them to establish her own rule. Her mind wiping abilities in particular could be used for all sorts of shenanigans from changing the history books to even wiping out Lufas' 200 years of history (if she didn't "die"). Her knowledge of doujin and also referring to an enemy as an "NPC" makes me think she could also be a developer or a player, but we shall see.
More than half the story felt "vignette" like, with perspectives from a child in a random village to a younger 20 (well, in elf equivalent years) something Megrez from the past. I would have liked a bit more in the present day, and it would have been nice to get just a bit more on what's going on with the demon realm.
In terms of content warnings, there's some really incel sounding crud in the early going with the main character. As the main character was a man in the real world, and now has the body + shares the mind + brain chemistry of his female avatar, he undergoes some changes in terms of his libido. And (please read this sarcastically, this is horrible) what better way to talk about this change in his mojo than when he's thinking about the naked bodies of two Goblin victims he just saved... Yeah. He also proceeds to gloat about how men who play female avatars are more popular than actual women online because "men know what other men want to hear". Yeah, I'm sure the women are broken up about not appealing to these dudes online. Finally he proceeds to call the goblins, who mind you kidnapped the women to have babies with them, proper gentlemen when it comes to wooing them and compares their plight to others unfortunate enough to be born by God with a raw deal in looks... ie, incels. That part was pretty entertaining in how awful it made the MC look, and I don't think that reaction was at all intentional. Some folks in the story are also sympathetic to dictatorial rule, looking back to the control + order of Lufas' rule as ideal, but I think it handled that better (Lufas basically saying that she didn't deserve to rule and has no say in future affairs, that the heroes should be proud and humanity should move forward). Kinda reminded me of how Dracul is venerated in certain countries in Europe while he was known as a vicious tyrant in his time.
The writer is kind of harsh on himself in the outro, a bit defeatist in saying to buy this for the illustrations. But they clearly did something right for this series to go as many volumes as it did. There were some elements that it sounded like they added to chase popularity though (the "boy that looks like a girl" side character), which I don't really care one way or the other about, just should be noted as I know some don't like when stories have a sort of "by popularity / by demand of contests" stuff in them. I will read more, but volume 1 was just a bit forgettable.
