I don't have much to say that has not already been said. This novel has an uninspired plot comprised of repetitive tropes and bogged down by the harem and uni-dimensional side characters.

That said, it does a decent job of fulfilling the tropes that are to be expected with this genre. In particular, I disagree with a comment by toyyoda:

"Recycled plot of 'an enemy pops up which puts all of Earth/another world in danger, but our MC is just strong enough to beat it, hence he gets amazing abilities and rewards... more>> which coincidentally synergise with his existing abilities and will counter the next enemy that comes along'. Battles are nothing beyond a display of MC's abilities and showing how he's stronger than these Goliath-like creatures."

This is by and large what should be expected from the genre. DBZ among many many other fictions face this same issue; some handle it better than others but in the end it is somewhat unavoidable. The fictions that surpass this, or rather achieve a suspension of disbelief from the reader that surmounts this, is hard to find outside of published works. I would even argue that any "power system" that provides quantifiable tiers of power will struggle to convince the reader to care.

What ICDS does particularly well (at least in the first and last 50 chapters) is the fight scenes. The movement and action are easily visualized and have weight. Sadly the middle does suffer a bit from the issue of "special moves" cluttering up the combat. Overall this factor was what made ICDS stand out for me. <<less

It's good. Far from perfect as Toika made several of overdoing and underdoing in this like the Harem and the world building. If your story revolves around world travels and game elements, I believe it is not advisable to make it a 1st Person POV as it limits the perspective of the story to a single person.

Thankfully, Toika learned from that mistake and did a better job on the novel that succeeded this one which Everyone Else Is A Returnee.

Good dungeon story, enjoyable and well-written fight scenes. -1 star for another really boring harem, filled with tons of nonsense (It's a realllllly boring harem in general, only reason its not -2 is some decent comedy, but most of it is bad.).

I like the fact that it combines some of the typical JP novels clichés with KR novels. The chemistry is great, I like the fact there are tsunderes and the MC got a harem while he isnt some kind of adult in a 12yo body with a bunch of lolis following him around. The story is interesting and refreshing.

Would recommend 1000 times if necessary

I don't review ln/wn as much but this one is a gem so I had to share my thoughts/opinion.

I normal get bored with story which focuses too much on dungeon but this one is written so well, the balance between how much time characters get->the world building->skills->grinding->comedy->explaining bits of information is just perfect as it can get for me. Without spoiling anything, I would recommend it to anyone who likes leveling type (even though you will feel it isn't all about leveling and grinding), plus our MC isn't perfect since... more>> he is only a human. Give it a try and just after first 10 chapters you will be hooked! <<less

This one is one of the best dungeon grinder series. The series emphasizes comedy. The downside is, the enemy becomes less threatening as the MC become more OP. But the story is still interesting because how MC plays the role as the hidden hero.

Ok honestly I was on the fence at first but most doubts I had about the quality of the story have been resolved. It's fun and easy to read. The characters are colorful and actually have understandable personalities with individual thought processes. The levels of the dungeon allow for a gradual progression of the story, and dramatic foreshadowing hints at interesting things to come.

Albeit the characters' individual personalities can be weird at times, but thats true in reality as well. (E.g. The Mc's eerily strong love with his sister).

I hope... more>> it keeps getting better and that there's lots more to read. <<less

Rating 5/5. As I have fully read all the chapters of the story, from introduction till the end I can say it's a wonderful story. The story is about the MC getting stronger in a dungeon. The story is a slow paced one but still their are a lot of laughs and jokes in the early chapters of the story, and as for the romance it's wonderfully developed with a lot of character development I to each character. (Well it still ended in the harem route.

As for those who are... more>> planning to read the story it might be wonderful if you like slow paced stories.


Ps. Ending of the story was a cliff T.T (wasn't able to see the marriage part, author ended the story as where you want to finally watch the hero get married.

I've read this novel a few years ago but I dropped it. I recently began rereading it again from chapter 1 cause why was curious why I decided to drop it since I'm a big fan of EER.

Soooo.. I regret my decision. What I like about the author is that he is creative in terms of world building and his power system development. However characters are mostly one dimensional. Toika said in his author note that the novel isn't harem but all the girls just magically fall for the MC.... more>> Like it's not enough that they like MC, they even force themselves upon him. MC has a sister, even the sister is the same which is disgusting.

They novel is not harem but most of the chapters deal with MC's interaction with one dimensional girls. At some point reading just became a chore. Just get on with the plot. After some chapters I'm dropping it again for the last time. <<less

Started off really nice and funny but I had to drag myself to read the last 20+ chapters or so. Ending was also rushed. Other than that, it was a decent read and I actually enjoyed it more than I Reincarnated for Nothing.

At 255 right now, will update if and when I finish. So far? 4.0 but I am extremely easy to please. I just like novels that will pass the time and have an enjoyable story. This is no titan like Overgeared, The Second Coming of Gluttony (or Avarice), the list goes on. If you picked your favorite story, this won't stack up with that. That being said, I think that it has been worth the read so far. An annoyingly dense protagonist who will most likely end up marrying all... more>> of the females in his harem who continuously fight over him (to which he acknowledges but pleads innocence.) In terms of power, it's interesting and I wouldn't say original but not annoying.

I am simple. A protagonist who starts out or becomes overpowered with enough chapters for me to binge read. If that sounds up your alley, give it a shot. <<less

The story was interesting, the worldbuilding was good, but the ending was so rushed it leaves a bad taste in my mouth.

It was at least fifty chapters short of what it should have been and the last two chapters compressed most of that.

The characters were okay. A few stood out slightly, but nothing really outstanding. All in all, I enjoyed it until the last 10-20 chapters, but the ending brought it down to ☆☆☆ and killed my mood

I don't have enough enthusiasm (positive or negative) to go into further detail... more>> except for the incorrect and extreme overuse of the word 'retort' (used instead of every instance of respond). Whether that's the fault of the translator, or the author, I have no clue. <<less

Having read it from start to finish I liked the overall storyline. My only exceptions is of course how dense the MC can be with regards to the harem and how ending began to form a wash, rinse, repeat feel.

And another novel finished! I loved this novel from the very beginning. After reading another work of this author, the "Everyone Else is a Returnee" (which I strongly recommend) I came I love everything this author writes. I really like how the protagonist is awesome both in power and personality and how all the other characters as well are awesome. The comedy is great as well and I can never get enough tsukkomi, it really livens the conversations, doesn't it?

Anyway, long story short I really recommend this novel, 5 stars... more>> from me. <<less

For now I think that this novel is a good read for a selective group of reader as this although not much in my opinion has certain similarities with EER, though I like this one better as although the MC is OP not OP to the extent that it's annoying as it's not an instant OP like EER (I stopped reading EER around the middle since I couldn't take it anymore)..

The story is pretty much relaxed & kinda smooth sailing for the MC but since I already expected it since... more>> I've read a few reviews before reading this so all was within my expectation except that it was actually a good read. My suggestion is to read this without any expectation so you won't be disappointed.

Now what I like about this is the MC. The MC here is quite different as that he started as a muscle-brained martial artist all until he started inputting stat point into his intelligence, also although he has a high INT it was explained that his brain is still "updating" so you don't need to expect him to have genius like actions. Also unlike EER I could see how the MC here grows from zero to hero.


Right now I don't know if there is a reason why the MC became a Hero but who cares why he is chosen at the beginning, it may eventually be revealed or not but is it really that important? In my opinion what the MC's attitude by being hero is more important. At the start the MC's action maybe be called a little cold if seen from a different perspective, but really I think it's logical, there are monsters appearing everywhere you don't know why this is happening although you can hunt them there are a lot of people who are a lot stronger than you so why bother helping killing monster that don't bother you instead the most logical action is to train in the dungeon. But later it was revealed that the appearing monsters have a lot to do with him so some people who don't take time to think why will think he had a sudden turn in personality, if someone told you that monsters/dungeons will appear in large scale in the near future who are outright trying to kill you who would be s*upid enough to just wait for them to grow in numbers, MC might be strong or maybe even OP in his world but he is still one person with limited MP/mana.


The although the MC is dense he is not dense to the point that he won't know what the other parties feeling if they convey it straight to the point. And I think he is not a scum since the girls that confessed to him IIRC were rejected by the MC although the author seems to want the MC to have a harem since they won't give up. I won't go into details about the harem the MC is making since quite honestly I've already expected it since like I said I've read some reviews about how quick the girls are falling for the MC (which was explained that it's because of his charm stat he couldn't control at the start).

The story is pretty simple MC is a dungeon explorer that can train in a different dimension dungeon. He learns about things why monsters start invading his world bit by bit. He grinds boss for stat equips & bonuses. When MC is strong enough it's time for him to confront earth ability users. Then back to grinding in the dungeon after resolving problems back in his world. Mostly are rinse & repeat but the story is mostly progressing faster & faster as he climb the dungeon.

So far I quite like this novel (although I don't know for sure since I've only read about half of the story) so for now it's 3.5-4/5.

P.S. There are a lot of japanese references so those who don't read any JP anime/manga may not get some jokes or "tsukkomi" <<less

Korean novel, which automatically means less bullsh*t and garbage filler compared to CN novels. It's a fun story, but some of the characters are annoying (his sister & ludia), which is probably what the author intended, but still lowers my enjoyment, so 4 stars.

I would go with 3.8 but 4 stars would do.

Interesting but really repetitive. I don't really like harem romance either, since they seem really shallow.

I kind of skipped over the last few battle descriptions and got to the point but unfortunately, the majority of the story are battle descriptions so it would suck if I had to keep doing that..
