1)Death Note :
Synopsis
A shinigami, as a god of death, can kill any person—provided they see their victim's face and write their victim's name in a notebook called a Death Note. One day, Ryuk, bored by the shinigami lifestyle and interested in seeing how a human would use a Death Note, drops one into the human realm.

High school student and prodigy Light Yagami stumbles upon the Death Note and—since he deplores the state of the world—tests the deadly notebook by writing a criminal's name in it. When the criminal dies immediately following his experiment with the Death Note, Light is greatly surprised and quickly recognizes how devastating the power that has fallen into his hands could be.

With this divine capability, Light decides to extinguish all criminals in order to build a new world where crime does not exist and people worship him as a god. Police, however, quickly discover that a serial killer is targeting criminals and, consequently, try to apprehend the culprit. To do this, the Japanese investigators count on the assistance of the best detective in the world: a young and eccentric man known only by the name of L.
2) Shingeki No Kyojin (attack on titan ) :
Synopsis
Centuries ago, mankind was slaughtered to near extinction by monstrous humanoid creatures called titans, forcing humans to hide in fear behind enormous concentric walls. What makes these giants truly terrifying is that their taste for human flesh is not born out of hunger but what appears to be out of pleasure. To ensure their survival, the remnants of humanity began living within defensive barriers, resulting in one hundred years without a single titan encounter. However, that fragile calm is soon shattered when a colossal titan manages to breach the supposedly impregnable outer wall, reigniting the fight for survival against the man-eating abominations.

After witnessing a horrific personal loss at the hands of the invading creatures, Eren Yeager dedicates his life to their eradication by enlisting into the Survey Corps, an elite military unit that combats the merciless humanoids outside the protection of the walls. Based on Hajime Isayama's award-winning manga, Shingeki no Kyojin follows Eren, along with his adopted sister Mikasa Ackerman and his childhood friend Armin Arlert, as they join the brutal war against the titans and race to discover a way of defeating them before the last walls are breached.
3) Fullmetal Alchemist: Brotherood :
Synopsis
"In order for something to be obtained, something of equal value must be lost."

Alchemy is bound by this Law of Equivalent Exchange—something the young brothers Edward and Alphonse Elric only realize after attempting human transmutation: the one forbidden act of alchemy. They pay a terrible price for their transgression—Edward loses his left leg, Alphonse his physical body. It is only by the desperate sacrifice of Edward's right arm that he is able to affix Alphonse's soul to a suit of armor. Devastated and alone, it is the hope that they would both eventually return to their original bodies that gives Edward the inspiration to obtain metal limbs called "automail" and become a state alchemist, the Fullmetal Alchemist.

Three years of searching later, the brothers seek the Philosopher's Stone, a mythical relic that allows an alchemist to overcome the Law of Equivalent Exchange. Even with military allies Colonel Roy Mustang, Lieutenant Riza Hawkeye, and Lieutenant Colonel Maes Hughes on their side, the brothers find themselves caught up in a nationwide conspiracy that leads them not only to the true nature of the elusive Philosopher's Stone, but their country's murky history as well. In between finding a serial killer and racing against time, Edward and Alphonse must ask themselves if what they are doing will make them human again... or take away their humanity.
4)Naruto: Shippuuden:
Synopsis
It has been two and a half years since Naruto Uzumaki left Konohagakure, the Hidden Leaf Village, for intense training following events which fueled his desire to be stronger. Now Akatsuki, the mysterious organization of elite rogue ninja, is closing in on their grand plan which may threaten the safety of the entire shinobi world.

Although Naruto is older and sinister events loom on the horizon, he has changed little in personality—still rambunctious and childish—though he is now far more confident and possesses an even greater determination to protect his friends and home. Come whatever may, Naruto will carry on with the fight for what is important to him, even at the expense of his own body, in the continuation of the saga about the boy who wishes to become Hokage.
5) Tokyo Ghoul :
Synopsis
Tokyo has become a cruel and merciless city—a place where vicious creatures called “ghouls” exist alongside humans. The citizens of this once great metropolis live in constant fear of these bloodthirsty savages and their thirst for human flesh. However, the greatest threat these ghouls pose is their dangerous ability to masquerade as humans and blend in with society.

Based on the best-selling supernatural horror manga by Sui Ishida, Tokyo Ghoul follows Ken Kaneki, a shy, bookish college student, who is instantly drawn to Rize Kamishiro, an avid reader like himself. However, Rize is not exactly who she seems, and this unfortunate meeting pushes Kaneki into the dark depths of the ghouls' inhuman world. In a twist of fate, Kaneki is saved by the enigmatic waitress Touka Kirishima, and thus begins his new, secret life as a half-ghoul/half-human who must find a way to integrate into both societies.
