I wanted to find some other mangas from Daisuke which are worth reading,and i found this one. You should give it a try if you like weird stories with interesting ideas, so i will get straight to the point.

[Story - 8]
World Embryo has story which is intriguing as many things are happening. The appearance of Kanshu(demons), jinki users and the organization they work for, and embryo from which a little girl is born, and also the main character and the message he got on his cellphone from his dead relative, who got in all of this. Everything in the story is connected deeply, but the story itself has some twists which happen when you dont expect it and thats what it really makes it even more interesting.
From the begining of the manga, Riku gets a picture on his mobile from his dead sister Amane with hospital behind her. When he goes to investigate he is attacked by Kanshu, mysterious beings which are transformed from humans after they hear strange cellphone sound. Riku is then saved by his old friend Youhei and his partner Rena, and finds a strange embryo. The next day though he doesnt remember anything except for the embryo, which he starts to keep. Eventually from the embryo girl Neene is born and he starts to remember everything that happened. After a short while they are attacked again and due to the serious wound he got from kanshu, Neene saves him by turning him into a kanshu which keeps his own mind. But many other things keep happening since nothing is normal again. *telling the rest would be a spoling so read it yourself to find out*.

[Art - 9]
Daisuke Moriyama is truly gifted artist which he showed in this manga as well. Its very well detailed in both characters and the backgrounds. There are some scenes and images which really left me impressed, especially the colorings on the special pages. Characters are well drawn and they really do have the similar style of his previous and current works. He draws battle scenes good enough so you can follow what is happening, and i love the use of blood, since where it is needed he draws it. I personally love bloody manga as it makes it more real then saying " is this guy even human when he is supposed to be"?

[Character - 8]
What impressed me are the characters in the whole story, they have strong connection and personalities. Though i still gave it an 8 because their backgrounds - pasts are just hinted and its more focused on them in present.[update: finally things are becoming clear and the characters have their pasts revealed, and i must say, in interesting way]
The main character, Riku Amami, is specialized in telling lies, which makes the whole story even more interesting,because it makes him get out of bad situation easily. Though as we all know, lies can only bring harm afterwards. He learned that, hard way. Riku has deep connection with Neene, which makes him really protective over her, and wont allow anything to happen to her, which makes him ready to do anything to stay true his goal (i cant say it without spoiling so you need to find it yourself) and by doing that, obsessive. His whole character is complicated but its exactly what i loved. He is not either all goody goody, because he tends to use any means he can to protect himself and his dear people.
Neene is a mysterious girl born from embryo which looks like Riku's dead relative. Neene is not a human, as you can see hear ears for example. She calls Riku Papa and Rena Mama which is really cute. She also grows faster than any human making her more like riku's relative. But by the time she gets protective, smarter, and has a caring and funny personalities. She dislikes fights, especially when her mom and dad are fighting.
Rena is usually quiet and serious girl who tends to do her job properly, but really kind in heart. She almost never smilies but after meeting with Neene and Riku, she started to change and become a different, and more opened and friendly.
Overall the characters in this manga can just surprise you.

[Enjoyment - 9]
The whole setting of story and characters, also action scenes and everything else made this manga quite enjoyable and keeps your interest if you read it enough to make you go crazy XD.

[Overall - 9]
I just think if should be made into anime, that it would be even more better, as this manga deserves more love. And if that happens, it would surely make me and other fans of this manga happy. I still strongly recommend you to read. Enjoy!
