From Tokyopop:

In real life, Roto, Boromid and Ah-Dol are average kids with average problems, but in the virtual world of Lost Saga, they're heroes. They might even become legends... if they can stop bickering long enough to level up. Whether it's werewolves running rampant or a gorgeous pair of troublesome thieves, our boys must be ready for anything, because in Lost Saga nothing is what it seems and murder can happen with a click of a mouse.


The series centers on the main character Jang-Gun and his friends along with their virtual reality avatars in the computer game world called "Lost Saga". When Jang-Gun logs on as a different character, he "Creates" an AI with a personality from the hacked disk he found when renewing his appearance for his once a year renewal process. Yureka is a flutter-brained, but advanced, AI with powerful stats and a real-life doppelganger. It is his turn to see just how deep his immersion in the virtual world goes.

My first impression of this series is good, The art is good, the story is ok and I love the characters. I read few first volumes, but never really put much interest on it at first. Then after a while, I decided to pick it again around volume 27. My impression on the art hasn't change. The story is still good, obviously there are things I don't really understand, which is fine considering my long time absence on reading it, the only problem I have is with the pace, it feels a bit slow for a fantasy story.

For a shonen this is a quite good read. It has some good ideas around the virtual gaming world and interesting story line too.

Started out good, was entertaining for the first 2 arc but then the decline started and players started to Bend Laws hack wack and totally destroyed whatever Universal laws the game has

It's become so Convulated that half the time you will be scratching your head as to what is happening and the other half is soo random that you just won't care

MEH don't waste your time on this one

after reading this manhwa, as a big fan of online gaming, i wish there will be an MMORPG game in the near future that will be created by adapting from this manhwa... while reading the manhwa, even though sometimes i find my self getting bored by the plot, i always think that the concept of Lost Saga game (such as the players are allowed to master more than one job and developing their skills with their own brain) in the story is really something desired...

for a game that supposedly replicate reality perfectly, Lost Saga and it's evolution is shallow

first of all, after 33 volumes of translated part, Lost Saga only ever show 1 city
I don't know whether the game really only has 1 city (what kind of MMORPG is this) or the author just simply don't bother mention any other (i think this is the case). The same with all the dungeons, hardly ever mentioned before (except land of dragons) and only mentioned when they already arrived on the spot.

The Lost Saga universe seems so empty, there were never any clarity about how wide the game world is, skill tree, game functions and limitations. All the information only shown when it's convenient for the plot. Dungeons and skills are seems to be pulled from someone's ass.

world settings aside, the best thing of this manga is the characters, all of them are alive and unique. There are so many recurring characters in Yureka, but they all leave deep impression and one can hardly ever forget them.

the plot is also quite interesting and the continuity is amazing. it's just very unfortunate that it's not perfected by a good world settings.... it has the potential to be the best online game related manhwa, but it failed to achieve that. Still, this is a good read.

Cerebrus syndrome

Started out decent and was even funny at times, by the time I got to volume 25ish I lost all interest in this series, tried continue reading in the hope it got some of its original vigour back, but alas even 4 volumes later nu such luck.
Pretty much all the characters became very tiresome and the antagonists are uninteresting, annoying, and make no sense. Every last bit of humour has left this series and there is no solid story to make up for it.

This manhwa is definitely suffering from a heave case of cerebus syndrome.

Will not rate it because I enjoyed about half of what I've read, and disliked the other half very much.

love the series it takes a few ch to get into though but afterwards u will fall in love with Yureka's naivety its just to funny combined with our Evil sadistic Main char Lotto. After you finish the first arc i reccomend to continue onwards. Everything in perspective will come together concerning Yureka. It truly becomes a conspiracy /love triangle biggrin anyways cant wait for next chapter!!

I was interested at first. But it becomes too apparent after a few volumes that the author refuses to do interesting things with the story. There could be a lot of entertaining things done with the RL aspect of the story, but that is largely ignored. Too many characters and plot elements are introduced when there could be more character development and interactions with existing characters and plot elements. The fighting is mostly boring.

I don't really want to talk about how "hackers" are portrayed in fiction, and it's best if you ignore those parts too.

The series is overall a solid shounen series and I was drawn into it because the protagonist was said to be a selfish and calculating one. He didn't turn out to be the heroic uncaring sociopath like I'd expected (while he wasn't a crybaby either), but the quick pace, nicely-done fights and the ever-increasing level of absurdity (in a really good way) just keep pulling me back to the series. That's always been a strong point of fighting manga, and this series probably nailed it.

Judging from the last chapter I read, it looks like there's still a lot to come. I was literally glued to my seat for the latter half of the first arc, and if the author can pull that off again, I'm all for more.

Read it for Rotto

Come on, a selfish, smart, and sly SHOUNEN hero? I was hooked. Normally you have the main character who is as dumb as a block and probably with a head as hard as one. He will jump in front of a bus to save his friends, nakama, family, etc. Not Rotto. Oh no, this guy will gladly throw his friends under the bus. And then laugh. Luckily, he is still likeable when he shows his nice side. Which is hidden deep, deep, deep, deep, down. You'd probably need a team of miners to dig that deep but still.
I really liked the first arc but the second one is sort of...blah. Rotto doesn't improve at all, in fact it seems as if he has gotten weaker, and the funny Yureka is gone. Replaced with this "assassin" or hunter, killer, whatever girl. I think more than a volume is wasted with her moans about how she can't kill someone and how she wants Rotto to suffer because now she has a crush on him. Yeah. Stick to the first arc guys.

A fun manga that seems a bit long

Probably the best thing about this manhwa are the characters, particularly the main, Rotto (or Lotto). After a while you just get tired of your classic shounen justice focused leads and Rotto is about the closest thing to a cure as you'll find. You wont hear a "must save everyone" speech from this guy. He'd probably sacrifice his friends for a power-boost if he could-without asking first. He's pretty evil, and maybe not the brightest tool in the shed when it comes to interpersonal relations, but he's actually relatively smart, which is a plus. He's one of those character that even if everyone he crosses in his world will hates him after, you wont.

All of the characters are pretty extreme, but it helps to keep them unique from each-other. Although the art might not be to everyone's liking, its really quite good in its own way. Particularly in that the artist is able to differentiate her characters in ways other than hairlenght. This is a rare manga that even if a you haven't seen a character for volumes chances are you'll remember them (even if your character/person remembering skills are as bad as mine). They're all "endearing" in their own way and the story would feel like its missing something if they weren't there. Even the extremely minor ones.

The biggest problem I find with this series is that its a bit slow. It can spend volumes on something that could have been substantially compressed. In particular, the series spends way too much time (I find) twiddling its thumbs between major events. You can expect volumes of interlude material between the conclusion of one major issue and the start of the next. Admittedly its during these times a lot of character information is released, but it makes things feel choppy and a tad tedious. A battle of epic proportions is looming on the horizon and you'll be continually informed of this, but you'll have to wade through 3 volumes of characters talking and hypothesizing (and mauling each other). You just start thinking "get on with it already, I want to see something get smashed other than Boromir's face (which is still amusing 25 volumes later)."

Overall I'd give it and 9.
The art is pretty nice: the characters are recognizable and if you shaved everyone you'd still be able to tell them apart, action is clear and fluid, and I find the style to be pleasing. 9/10
Characters: Rotto is awesome and rest are all memorable. However, other than maybe Rotto and Yureka there isn't a whole lot of character development and they're all pretty flat. They're who they are and they stay that way. However, they're all interesting enough and don't follow flat archetypes so you don't get bored of them. 9/10
Story: The overall plot (once you get there) is pretty cool and takes on vast proportions. Due to the extreme nature of the characters the plot isn't as predictable as most other shounen, though you may have a vague idea of where things are going. Unfortunately its a bit stop-go in nature. 8/10
