Modern Japan (and the rest of the world) has been ravaged by a virus, leaving almost everyone above the age of twelve dead.
Monsters called the Four Horsemen of John have come into the world, eating humans they cross. Vampires, afraid that their food supply would be lost, have come out and made human children as their livestock.
Yu, Mika, and the rest of the children of the Hyakuya orphanage are livestock to vampires. This has been the case for four years: living in a city made by vampires that they can’t get out of. Yu hates it, but the person that he feels like is his brother, Mika, feels that by giving his blood, his family (the orphanage) can escape. Something goes terribly wrong in the plan, and Yu is the only one who escapes, vowing to get revenge.
Four years later, at the age of sixteen, Yu trains to be in the Japanese Imperial Demon Army, made up with Japan’s last humanity that fights the Vampires. But what if he meets new friends who can become his “family”, knowing that he is haunted by his past? And what happens when he gets a demon to wield, who tells him that he is not totally human?
This manga is wrapped in chaos, fear, and mystery, making it a very good plot to follow and keep readers on the edges of their seats. Additionally, there is a lot of unexpected comic relief, so this is not a serious manga like Attack on Titan usually is. The characters in this dystopia world seem very real, as though they were people the reader would know. Finally, the drawings are amazing; both action scenes and scenes of down time (school, suspenseful scenes, etc.) are well done and very thorough.
If anyone is looking for an action manga that is not too serious, this is one to read. However, although it can be found in Barnes & Noble, it can not be found in the Mission Viejo Library.
