Currently Ongoing (Since August 2015)
By Kazuma Kondou and Kataoka Jinsei (who brought you Deadman Wonderland and Eureka 7)
Genre: Shonen (it also has lots of horror elements imo)
The story follows Kakujou Youkou, who lives in a seemingly normal world where medical technology has skyrocketed to new heights, making it possible to completely replace any human organ. Those behind this are called the Ame No Tori (Rain of Birds), but it all turns out to be a plot against humanity where the new technology can take over its host, thus turning them into a killing machine. A task force is created called the Jackalope; its goal is to annihilate these mindless murderers before they raise any more havoc. This is where Youkou's new life begins...
First impressions: Some things the characters do don't seem very logical or make much sense following the next scene. But I attribute it to the fact the main character is such a weird guy in general and has a very strange set of self-made rules to follow. The concept itself is rather interesting (especially the Jackalope weapon concepts). The Rain of birds turning people to monsters kind of reminds me of... nah, I'll spoil that series. But whatever reference I made, it goes much further than that and it's due to the fact that it's an openly known business and has a general societal approval. The beginning is quite a shocker (I'd say just as a shocker as DWML's opening chapter, but I don't think it surpasses that) and a bit odd in some parts in terms of writing, but it's probably to keep things mysterious. I'm interested in reading more of this series so I can get inside the main character's head. Though it seems that he too is an orphan only with a sister (but seems much ballsier than Ganta).
