They are as follows:

Jenny: Bartender and owner of a bar in District 49, also a broker of unusual qualities, she has connections with pretty much most of the underworld of Balkan.

Evelyn: Government agent, she's essentially a member of the special police force of the city.

Aris: Sinclair's Tower prodigy and professor at Labathenon Magic University.

In my opinion, This is a masterpiece among fantasy novels not because it's perfectly written, matter of fact is there's still flaws in the novel (I will list the flaws later) but it was thoroughly compensated by the amazing world building and very immersive plot. This universe is complex and cruel. What really sets this novel apart from other fantasy novels is the protagonist's continued realistic growth and complexity of worldview. Stable development without sudden unexplained factors. No s*upid plots and inconsistensies especially in regards to many novels where the MC is suddenly being dumbed down and hypocrite just for the sake of plot development. No annoying characters and damsel heroines, no unnecessary harem and forced romance plot. (Not saying there's no potential romance, it's just not the main focus of the novel)

The unique worldview, which is a mix of cyberpunk-like machines and magic, is well incorporated into the work, and the main character's genius talent has a huge penalty, so even though he has overwhelming talent, there's a balance. The process of disassembling and incorporating the principle of magic and weaving it with talent, rather than feeling like unreasonable and too broken/OP, it's more like 'Oh, so this is how it works?' The way how the author explains and construct these things is what prevents it from feeling too broken. Thanks to that, the incident is moderately tense, battle scenes were top tier and immersive, and the level of adversity is well set to the extent that you can feel MC's growth.

I personally think this is by far the best novel with a wizard MC and magic settings that I've ever read. I also like the realistic and detailed magic expressions and explanation of author which makes me wonder if he is a real wizard with how he even thought of the magic and ability concepts here. Whether it's magic, summoning, martial arts or any mechanics was properly delivered and well blended in the series. The depiction of the dystopian worldview is well harmonized, and the setting for magic and the realm of enlightenment are really appropriate. Most of all, I liked how the MC made his own decisions without being swayed by anyone and being consistent in his beliefs and putting his own interest first throughout the series. The characters were fine, it was well developed and fleshed out. Now some might argue that the characters were boring, dumb and lacks individuality compared to the MC especially in the first half but I assure you that is not the case.

The obvious flaw of the story is the typical repetitive pattern in every battle results which is very prevalent in every novels. In most cases, there's a strong feeling that the battle results will be in favor of the MC in the end even though the tension and difficulty is really high because obviously that's the normal troupe for every novel where MC will overcome the struggles and challenges in every novel. Don't misunderstand that MC here is snowballing every fight, the fight is properly balanced and the enemies are smart and they're making the fight really difficult. Sometimes MC will encounter a more powerful character, sometimes he will also encounter an unfavorable fight due to a lot of factors like bad matchup/compatibility or bad environment, sometimes even encountering it in a bad circumstances, which force him to escape or put him on stalemate. So if you like a novel where the MC is getting defeated or getting whooped then this is not for you. Cuz this can cause some people to feel the tension were going down as you go along the story but good thing is author's writing ability were really good and the battle scenes are impressive, immersive and properly explained which shows that MC really did overcome the difficulty instead of snowballing every fight.

2nd obvious flaw that other people might say is the lack of romance, If you read the story then you will understand that this has something to do with the worldview and development. It's not that there's no potential romance however it's just not the main focus of the story and it's being required by the plot. MC is busy struggling for his life in a world where he doesn't know if he can achieve his goals and get answers or if will eventually fail in the end. Matter of fact, this topic actually caused a minor controversy that caused a lot of people to spam lower ratings on other platforms due to author's remark. Why would he or the plot development lean towards romance instead of focusing on the original premise. So for readers who like harem or romance, this is not for you.

There's also very few minor plot changes caused by author revising some of the setting but it really shouldn't matter cuz it didn't affect the overall development and you will really not notice it except if you will remember the previous dialogues or the early plots.

Overall, the narrative of the series is great. Every expression, decisions and actions of the characters, the concept of powers and level ups of abilities were properly explained. If y'all like a story driven series without any forced plot, unnecessary romance and annoying characters then this one is for you. The MC is properly driven with purpose and always stay true in his belief which is always demonstrated multiple times in the series. Of course this is just my opinion and everyone can disagree as we have different perspective and preference in rating a novel. To each their own.

FWIW, so many reviewers were comparing this to Genius Warlock that I went to read Genius Warlock up to chapter 44 (when I got bored).

Genius 'Warlock' is about an emotionally stunted teenager aimlessly following random people around out of curiosity about pretty lights. Genius 'Wizard' is about a normal transmigrated adult gamer who becomes a mercenary because of his ambition to survive and learn wtf happened to him.

They're not at all alike, unless you think every book with a mage MC is the same—which you shouldn't. 'Wizard' has way more action and the MC is more goal oriented. The magic systems and tone are totally different. IMO 'Wizard' is a lot more entertaining to read than 'Warlock' on a chapter by chapter basis, but 'Warlock' seems more thoughtful thematically. YMMV.
