This is my first review so let's see how it goes.

So, recently I was craving a psychological manga and randomly picked this up.
What a pleasant surprise.

Story: 10/10*
The story starts off in our main setting: the orphanage. The sun is shining and the birds are singing and the big happy family is having a meal together. Well, almost. This does not last for long, despair and sorrow will soon follow. This is the day when the main characters stumble upon the secret behind their home and its origins. The story is unlike any other manga I have read before and shows great potential. There are many plot twists in this story and I hope it continues to surprise. It also explores themes of philosophical and ethical nature which make you question your own values.

Art: 9/10*
Clean, consistent and most importantly, very good at adapting its style to the emotions behind each scene. Of course, this is a psychological drama and whenever you need a reminder, it will remind you. The scenery is always beautifully drawn. The world that has been created looks intricate and original. I also want to point out something that I rarely see done right in manga/anime. That is, the way different races are represented. I feel that there is good detail given in racial features which makes the art more realistic and universal.

Character: 8.5/10*
I would like to give this a higher rank, however, the main characters are rooted in some almost stereotypical themes.
BUT! This is executed in such a way that it does not bother me. I will briefly talk about the 3 leads (of the same age).
The main character, Emma, has the typical "I will be Hokage" attitude and while not the smartest of the 3, she shows great insight in times of need. She does not lack any emotional or physical strength and it's a breath of fresh air to see that in a female lead.
The third lead, and probably one of the most complex, Ray, is the typical lost soul, smart soul gone emo. His backstory is explored a bit more and we get to see the reasoning behind his actions.
The second main, Norman, is this virtually perfect character. He is as smart as they come and acts almost as a mediator between the 3, meticulously choosing his course of action in order to reach the best outcome.
If you are hungry for sharp-witted characters similar to the likes of L and Light Yagami look no further. And yes, that was pun intended.
There are of course plenty of other characters and many of those play with your head in terms of being classified as good or evil.

Enjoyment: 10/10*
I found myself so intrigued in this story, bonded with the characters and in awe of what happened. The pacing of the story is appropriate to its complexity and every chapter kept me on the edge of my seat.*

Overall: 9/10*
What I would like for the future of this story is more character development and a chance to expand and explore its world.

*This rant is based on the first 56 chapters of the manga so please keep that in mind while reading this review.

Some recommendations:
~ Go blind into reading this manga!
~ As a comparison of similar themed stories, this manga is a grandchild of Made in Abyss + Attack on Titan. This is based solely, on their anime related content as I have not read their original stories. If you have enjoyed similar themes of survival and raw emotion then you will enjoy this manga.
