Caidel lost everything, EVERYTHING, he ever cherished in a single fire, Black Butler style. Parentless, he was sent to an orphanage where he was ostracised for absolutely no reason at all.

However, misfortune has to come to an end at some point and it did. An Earl came to him, he was related to his past somehow and he was also devastated by the catastrophe.

He adopted him and gave the only clue he had about the culprit who set fire to his house. The culprit was a girl with white hair. So in short, just all of the older generation of women on Earth. Pretty valuable insight.

Those four students surely had the time of their lives in high school, as they should. They will never forget how great it was being trapped in that container.

All four of them were knocked unconscious out of nowhere and woke up in between four tin walls.

In a state of utmost panic, they started screaming for help, as if someone would hear them, and kicking the door as if they were superhumans and it would just burst open.

Okay, we can’t blame them, at least they tried, right? However, they have an easier way to get out of that mess. The perpetrator is only asking for one thing, for them to confess their sins and repent wholeheartedly.

I know I shouldn’t spoil the mystery, but keep in mind that I may be wrong. Who else believes that it’s some bullied kid taking revenge?

Mirror, mirror on the wall, who’s the most mysterious of them all? Tell me, what would you have done if you were facing a distorted version of yourself? A dark and evil version, a version that strives for the misery of others, always smiling, always contempt?

You’d lose your mind. Well, the main character of this Manhwa already did. Keeping it together thanks to pills, she will eventually have to face reality in the eyes, she’s a bit cuckoo in the head.

Her heart, someone or something wants it. It’s tormenting her in her dreams or more exactly her nightmares, it’s tormenting her at her work, at home, while taking a bath, everywhere.

Bright red lips, a sharp knife, and a magnificent smile shining on a face that looks exactly like hers, but that’s not her, right? RIGHT? That’s not her!

Mmm… If I had to compare this Webtoon to an anime I think it would be Parasyte. You all know Parasyte right? If not, well, google it duh.

A strange species from outside our galaxy made its way to Earth. They look exactly like us. Impossible to distinguish them from normal humans. And yet, I don’t know how but we found out about them and even gave them a name, Eaters.

When I read their name, I immediately imagined some gourmet alien feasting, and I was on point, it’s just that the main dish is us.

So those Eaters have a special way of communication, no matter how hard we try it’s impossible to comprehend them. There is just one girl on the entire Earth with the special ability to speak their language, her name is Yuli.

And instead of helping us, she went and fell in love with one of them. Nice going girl you know where your priorities lie. An alien human-eating boy > all of humanity.

One narcissist is incoming! It’s a mystery to me how girls can be so obsessed with looks and disregard everything else, and I’m a girl myself. We are so weird and so complicated, how can you handle us guys, really? I want your secrets.

So this MC completely lost it over a boy who obviously only has eyes for himself. The type that will gawk at his beauty in any possible reflective area and flex. Makes me wanna vomit.

However, there is more to our little narcissist here and that “more” is even creepier than what we already saw if you can believe it or not.

And recently, she updated her skill set and added detective to the list. Due to a certain turn of events, she was dragged into a murder case. Not that she’s sad about it or anything, she thinks she found her calling.

 Your first memory, when and where does it begin? A stupid question, right? Of course, you don’t remember, so why ask the question in the first place?

However, no matter how silly that question might sound to you, it will mean everything to the main characters of this Korean Webtoon.

Let’s travel back in time, to the ’90s to be exact. This is when their first memory began. Four young adults, all of them are 24 years old, all of them are leading very mundane lives, in other words, they were just plain boring.

Somehow, they were caught in the strings of a certain crime, a mysterious and horrible crime, a gruesome one. Now, all four of them are in grave danger.

To save their sorry butts they have to put their brain together, however, it’s when humans must cooperate that they never find some common ground…

 I don’t know why they didn’t add horror to the genre list because this one is a creepy one. A man, proudly covered in blood from head to toe is standing in front of a girl. The girl, she’s obviously terrified, she can’t stop shaking.

With utmost confidence, the man confesses his eternal love for her. If only real boys could be as honest with their feelings as he is right? Not saying they should kill someone to turn confident, don’t misunderstand, I don’t want my readers to end up in prison.

The man declares the following. A year from today, the girl will either spend all eternity by his side or she will die a lonely and terrible death.

A real romantic we got there, and he fooled us all, who would’ve thought that he was in fact cursing her.

From this point on, any man that would dare steal the love of the poor girl would mysteriously disappear from the face of the Earth, a fate, maybe, worse than death.

 Sori is just a child but she is way too mature for her age. I mean I’m 23 and I don’t think and act like her.

She understands the pain of others and can’t handle just standing there and watching them suffer. You know kids, they are just cruel at that age and like to bully mercilessly, so every time that happened she’d come to the bullied rescue until she became the target herself.

The miserable life she was leading turned into a fantastic adventure when she stumbled on letters that transported her to the magical world that lies beyond the barriers of reality.

The letters are addressed to her, they are the key to her happiness, who wrote them, and why, no one knows.

 If you are too good at something you become the target of jealousy. If you are too bad at something you are shunned by society. In this Manhwa if you are one or the other, that means you are a witch. Can’t find the logic here, but okay…

Two outcasts found each other, and mixing rage together is never good for the world. Resentful against everyone that ever rejected their very existence, they are planning to achieve ultimate happiness upon the misery of their bullies.

 Yoseob is a very posey and quiet child, however, the quiet ones tend to surprise us the most. Yoseob is at the police station right now. He didn’t steal anything, he didn’t hit anyone, he just stabbed 8 people.

We still don’t know if he really is the killer, he just really doesn’t look like it. But it’s creepy how calm he is in that nerve-breaking situation.

Is that a grin on his face? Maybe he did it! Does his brother complex have anything to do with it? He wouldn’t go that far to keep him for himself would he now?

 Adventurer Kim Su Hyun fought and grieved for more than ten years to get the ultimate power, the “Zero Code”.

The code can grant any wish and the overpowered warrior is at the end of his adventure holding it in his hands.

As he was thinking of what he desired the most, which is something he should already know since he put his life in danger for it, he realized that he lost way too much on the road.

He used the power, and his demand was to revert time, to go back to the beginning of his journey so he can try again but do it right this time.

That’s nice and all but couldn’t he have asked the code to give him back the people he lost? I mean its power is omnipotent, what an idiot!

 The Player That Can’t Level Up, the title is pretty straightforward, our MC awakened as an adventurer, acquired an S-rank ability, and was supposed to make a grand entrance on the battlefield.

It just happened that his ability is pure trash since he has been fighting for 5 years now and is still stuck on level 1.

Turned out that the idiot couldn’t figure out how to use his skill. When he finally did, he learned that he could level up weapons called “Egos”. Egos are extremely powerful and have wills of their own.

Bond with them, feed them right and you will turn into a killing machine yourself, however, you will revert back to a loser if separated from them.

They are double-edged swords that will bite back in the most inappropriate moment. Our MC has got to tread carefully from now on.

 A building collapsed over nine university students. They were trapped under the rubbles for 14 days without food or water.

When they were finally saved, only six of them survived and four of them lost their ability to speak because of the trauma.

When they recovered the bodies of the dead, they were unrecognizable and not just because a building fell on them.

The rescue case turned into a murder case just like that and all the survivors are now suspects. With only two sane enough to answer the police’s questions, can they even investigate properly based on that?

I personally doubt it and anyways what happened is obvious, isn’t it? They ate them Hannibal style, Dah!

 A boy shipwrecked on what looked like a deserted island. After exploring for a bit, he found out that a family was living there. A family and a man with a pig mask on his head.

From the looks of it, the pig boy had nothing to do with the family. Was he living there alone? How did he get there, he isn’t here by choice, is he? In fact, who is he? Why the mask? Where did he get the mask? So many questions are left unanswered.

And that’s not all, that family is super shady and so weird. There must be something they are hiding. But if they are the bad guys why are they the ones afraid of the newcomer.

Is the newcomer the villain here? I’m completely lost. If one of you can understand what is happening here please share your insights with me.

 The poor girl’s boyfriend didn’t just break up with her, it seems like he really despised and actually poisoned her to death.

The girl woke up in a novel where she incarnated a meaningless extra that was destined to be killed off as well.

To avoid another ridiculous death, she pretended to be the Duke’s fiancé, and well, that is how she ended up in his mansion if that’s what you were wondering.

Don’t worry, that’s not the big mystery of this manhwa, you can read and find out what it is… if you want, nobody’s forcing you… except maybe me a little. It’s a great story we got here.

 Just so you know X-ray vision is not for peeping at people and that comment goes for you girls as well. In the end, we can be as naughty as boys, we are just more elegant about it. Keep notes boys. That comment will help in your future.

Not only can our MC use X-ray vision he is also an overpowered martial artist, he learned fortune-telling, he is also quite a good medic, plus he is an artist and a refined collector… okay that’s way too much talent to pin on one guy Mr. Author.

The purpose of the story was lost in his perfection. I don’t think there is anything he can’t do, so just imagine a plot he’ll most probably end up victorious in all the scenarios you can come up with.

Unfortunately, her mother died as well and her disgusting uncle forced her to live with him. He treated her like trash and the only way to escape was to kill herself.

When she did, she went back in time, to the year her mother passed away. The joy she felt when she saw her again was nothing compared to the pain of seeing her close her eyes forever for the second time.

However, this time was a bit different. She drew her last breath but left a message behind: Your dad is still alive, go find him!

Everything changed when a transfer student arrived at his school. He gave him an opportunity, an opportunity that he took. He introduced him to the world of DICE, a world where all is decided through a single puny roll.

You can think of this manhwa as No Game No Life minus the cheerfulness.
