There's a couple times (not many) in volume 1 where the MC jumps the gun and mentions something that would be better to not be said around a certain sharp character but aside from that, I can't think of any other example of misunderstandings on the other volumes, well, besides the usual ecchi misunderstanding once in a while that is normal for ecchi series like this one.

The second one would be regarding the MC being a weak Demon King, this is actually something pretty subjective, he can make strong attacks with his fire sword and even with his fists, but one needs to remember that his main abilities are only 2 le*d magics and that's it, so it can also be said that he is a strong and a weak Demon King at the same time. For those who still think that he is weak, there's an explanation for that later on in the series, but well, this MC is the type that uses his head a lot more than other MCs of this kind of series.

Now going for a more objective view, for starters the series already tells you from the very beginning that the game is still under development and by the dialogues between the characters it's quite obvious that it's nowhere near it's completion so the classmates being strong (specially since it's mentioned that the speed of leveling up depends on each individual) and other game errors (that do appear later) s not be surprising.

For some people (like me) it makes things a lot more interesting since the MC has to actually face hardships and start using his head, which creates some pretty interesting developments later on, now for others that prefer when the MC is overpowered and just wipes everything without any problem it might be quite frustrating.

The third thing would be the MC being an idiot. He acts a bit naive in volume 1 and is quite confused about his situation in the beginning but, as mentioned before in this review, he is growing as the story goes on and takes more countermeasures against his enemies in case his first plan doesn't work as expected. Many of the demons not being that smart is already clarified in the novel, they're NPCs, and the type that would just be background characters, so aside from important ones like MC's four subordinates, the other demons, although not being complete idiots or nothing like that, clearly don't possess the same level of A.I. As MC's subordinates.

Now regarding the whole thing about him letting his classmates level up, he can't let his identity be discovered because if that happens it's basically certain death for them all, so he needs to act as a normal classmate with them and not attract attention, which would certainly happen if he suddenly started to always try to stop them from leveling up, plus, he can't always be with them anyways since if he neglects his subordinates in the demon side, their loyalty status might drop, which would make them not trust the MC anymore and they could even act violently against him, possibly trying to kill him too.

Here we will see if his classmates will believe, side, or fall to him after they taste his powers. One female classmate, leads the group, one is very sharp but has a secret, and his demon like employer is his s*ave. With our MC having a high position in heirarchy we will see how their fate will turn out.

MC is a idiot that made the demon lord an idiot and all demons are muddleheaded idiots. MC is wasting away his time letting "hero" rise 6 level from 17 to 23 in just 2 weeks unnoticed.

He was moving tr*sh for 2 weeks.

Oh and the last bos almost died 4 times in just first volume.

In the first battle he lost almost all 1000 hp due to few attacks because these newbs skills do 100/200 damage.

Because of the critters outside beginner town right next to the demon castle lmao his true level is 1 and critters can kill him in 3 or 4 hits.

When doubted by cold sorcerer girl in orc village.

In guild hall he lost 95%hp because of a single spell cast by lvl 15 newbie.

Weakest demon lord ever. How the f*ck will he ever protect anything the hero with his level 23 can probably instakill him now.

The author builds up a nice, sweet romance with the MC & Asagiri that leads to a dead end. There are a lot of girls around the MC, but he crushes on this girl in the beginning of the story, she's the girl he's always looking at and thinking about, no one else. The author spends a lot of time building these two up.... They actually go through quite a lot of development. The MC goes through hell and back to saver her time and time again. Then, they finally get to spend a night together and he confesses to her, and they grow close. It's nice. But then for "plot related" reasons she distances herself, starts calling him by his last name again, and then it... just ends. Asagiri here actually comes off as really cold, but it's just the author's fault I think. She's the only one who the MC shows real romantic interest in. After everything they go through together, she doesn't wind up with him... Feels bad...

This girl is a total failure as a heroine, especially for being the #2. Initially she comes off as rude and distant, but that's fine because we have 8 volumes to get closer to her, see her develop as a character while opening her heart right?... Wrong!

She starts with the "ice queen" template, and it slowly breaks as we see the MC getting closer to her. But honestly, she's only good for fanservice. Because her "real self" is even more ugly and insane than her first impression. She's only liked because of her good looks. Her personality remains awful. The MC does a lot for her, but she's always bad towards him. She loves his alter ego, but tries to mu*der him when she discovers his identity. There's a laughable scene where the MC and his friend admire her for, I kid you not, being incredibly selfish and self-centered regardless of others. I feel like the author kind of knew he messed up her arc, because she has less presence in the later volumes, for good reason.

She is the best girl, and my favorite heroine in the novel, so why am I upset the MC winds up with her? Because she's literally a side character most of the time. She doesn't have enough screen time, the MC constantly forgets about her, her role in the story simply isn't big enough. But the main reason is that, for 7+ volumes, the MC describes his love for Asagiri... Aikawa doesn't even get a confession, or a big moment at the end. The story never gives the MC the chance to express how he feels about her, or if his feelings have changed/developed, or how grateful he is towards her. So it doesn't feel compelling or satisfying at the end. The author's just like, "oh the MC is dating her now"... not exactly a good conclusion for 8 volumes of buildup.

The strongest and most handsome Chad in Class 2A, complete with niceness and winning personality as well, was hit with the premium Gacha Adult Only skill, forcing him to do pe*vert things in front of his class. The girls who are attracted to him become flabbergasted with how he groped the succubus' b**bs instead of fighting the Demon King, while the boys were furious and envious over how all the succubus went straight to the Chad. Because the Demon King successfully distracted them all, Class 2A ended in defeat.

Said Chad really suffered in reputation, and Kakeru realized the implications of his actions. Even though he understands that leaving the class in disarray will raise his chances of Class 2A's survival (Demon King must not be killed), he attempts to restore Chad's reputation and succeeds. It's really quite wholesome.
