Along his way, he meets the art of "production" and people that have mastered this art. Watch as a total novice creates a revolution in the gaming world and create the "ultimate" support class.
If you're looking for a VRMMORPG story with some actual plot or conflict, you've come to the wrong place.
The whole point of Only Sense Online is its slice of life-like nature, and its gender bender MC, and for this reason, people tend to feel on one side or the other when it comes to this light novel. It's been criticized a lot for how unrealistic the main character is (a guy, whose avatar is a girl in the VR world) and how nothing really ever happens, but, as its meant to be a nice, relaxing fluffy gender bender VRMMORPG where you can read about
crafting potions and polishing rocks, I would say that it accomplishes this quite well.
How so? Well, firstly, the story's mechanics of the VR world are actually quite fun to read about, as they are simple and easy to understand. Everyone gets a few "Senses", which can be anything, ranging from the ability to use swords, to fishing, or blacksmithing. This provides a great deal of variety in the story, as the author can pretty much pull anything out of his ass as a "Sense", which actually keeps the story fresh and interesting at times. For example, Yun later obtains the ability to cook in the story, and also the ability to climb. The author takes a great deal of effort to explain just how the mechanics of these Senses work, which is fascinating as it pulls you deeper into that fantasy world that we would all like to live in. You can really start to imagine how you yourself would prepare and craft certain potions as you read about the meticulous details of Yun's work, and how he (she) dries the herbs, crushes them, dilutes them, etc. getting it down to an exact science. Eventually, he (she) also gets a shop, and begins to craft many other items, such as gems, tablets, slimes, etc. all described very in-depth. Other VRMMORPGS would gloss over these details, since they would be more focused on actual story and conflict, but as this is essentially the main theme of OSO, if you enjoy thinking about these kinds of things, you'll find that OSO will provide in spades.
Secondly, Yun really hits my strike zone, and probably will hit yours too if you're into guys denying that they're actually cute high school girls on the inside. If you've tried looking for guys denying that they're actually cute high school girls like I have, you'll find that there's actually a lack of content out there. Most people don't write about it, or use it as a main plot point, which often means serious emotional conflict. If you're really just looking for just reading about cute high school girls that are actually guys, well, OSO can give you that without all of the other extra stuff. Yun's character is pretty average, always looking to support people, good at cooking and cleaning, consistently outperforming the other girls in the story in terms of girl power (though not in chest power), but the tsundere "I'm not a girl" is really the GOLD that you're looking for, and it's pretty common in the story. You'll read about how Yun gets his chest grabbed by his best friend, whose a guy, and then act bashful and tsundere, even though he's a guy. Damn. So cute. That being said, this novel is actually very innocent, with no serious romantic or sexual implications at all, just teasing here and there.
Okay, if you've read this far, you probably think i'm a gigantic pervert, but all joking aside, you'll have to be an audience that at least can enjoy these two points in order to enjoy OSO, since they are the main selling points of the novel, and basically a huge portion of it. The rest of the characters aren't too interesting themselves, and the fighting isn't too exciting either, and although there is a fair amount of it, it usually devolves into Yun drinking multiple revival potions to tank damage as he (she) is an incredibly weak character. And again, there is no point to the novel. There is no big bad, no goal that the characters are looking for, no interesting thought about how Yun (probably) is starting to feel uncomfortable in his guy body, nothing.
But, still, it can be interesting to think about what it would be like to live in a VRMMORPG, while getting some of that gender bender tsundere gold. If that's what you're into, then I recommend OSO, as I enjoyed it quite a bit myself, though I wouldn't say it's an objectively well written light novel. It's more of just a guilty pleasure kind of thing. Still, it fulfills its role well, and I quite enjoyed it.
