Fear, survival, instinct. Thrown into a foreign land with nothing but hazy memories and the knowledge of their name, they can feel only these three emotions resonating deep within their souls. A group of strangers is given no other choice than to accept the only paying job in this game-like world—the role of a soldier in the Reserve Army—and eliminate anything that threatens the peace in their new world, Grimgar. When all of the stronger candidates join together, those left behind must create a party together to survive: Manato, a charismatic leader and priest; Haruhiro, a nervous thief; Yume, a cheerful hunter; Shihoru, a shy mage; Mogzo, a kind warrior; and Ranta, a rowdy dark knight. Despite its resemblance to one, this is no game—there are no redos or respawns; it is kill or be killed. It is now up to this ragtag group of unlikely fighters to survive together in a world where life and death are separated only by a fine line. [Written by MAL Rewrite]

Several hundred years in the future, the resources of the Earth runs out, and the progression of the human race has stagnated. The world is now divided into "Units." A boy named Hajiki Sanada lives with his mother and sister in Unit 74, in a place called "Night Town," in which all electricity is shut down at midnight. The key in this story is an object called the GAD. GADs have the ability to reconstruct materials while reacting to feelings of an organic life. The size and shape of the resulting product seem to be different depending on the kinds of feelings that the life possesses. When Hajiki comes in contact with one by accident, it transforms into a huge robot—a Tekkoudo, or "Iron Giant"—which Hajiki names Lightning. And soon he realizes that he isn't the only one with a Tekkoudo, and must find out how to deal with those others who he feels are the "same" as himself. (Source: ANN)

In a world of constant war between humans and witches, there exist the "beastfallen"—cursed humans born with the appearance and strength of an animal. Their physical prowess and bestial nature cause them to be feared and shunned by both humans and witches. As a result, many beastfallen become sellswords, making their living through hunting witches. Despite the enmity between the races, a lighthearted witch named Zero enlists a beastfallen whom she refers to as "Mercenary" to act as her protector. He travels with Zero and Albus, a young magician, on their search for the Grimoire of Zero: a powerful spell book that could be extremely dangerous in the wrong hands. During their journey, his inner kindness is revealed as he starts to show compassion and sympathy towards humans and witches alike, and the unlikely companions grow together.

Van, a lanky and apathetic swordsman, is on a journey to kill the murderer of his fiancé. The only characteristic he has to go by is that the murderer has a claw for an arm, hence the murderer being referred to as The Claw Man. During his travels, Van happens to pass through the city of Evergreen, which is defending itself from bandits who aim to rob the city of its treasury. It is in this city that Van meets Wendy Garret, a timid young girl who is looking for her kidnapped brother. When the city pleads for Van's assistance to defend it, he refuses, claiming it has nothing to do with him and thus leaves the city on its own to deal with the peril. Soon after, Van comes across the raiding bandits himself and they eventually tick off the swordsman to a degree where he takes action against them for his own personal vendetta. Surprisingly, Van learns that the bandits had ties with The Claw Man, and in kidnapping Wendy's brother for a reason they did not disclose. After the bandits are dealt with easily, Van and, much to his chagrin, Wendy continue the journey in search of The Claw Man. Little do they know, however, that The Claw Man is involved with something more atrocious than either could fathom. [Written by MAL Rewrite]
