All You Need Is Kill  A manga adaptation, written by Ryōsuke Takeuchi and illustrated by Takeshi Obata, was serialized in Shueisha's "Weekly Young Jump" magazine between January and May 2014 and was also published by Viz Media in its "Weekly Shonen Jump" magazine. In November 2014, the Viz translation was released in a collected edition that included the entire series. A graphic novel adaptation was released in North America in May 2014. A film adaptation from director Doug Liman starring Tom Cruise and Emily Blunt, titled "Edge of Tomorrow", was released on May 30, 2014. The English-language film tie-in edition of the novel also uses this title. The story is told from the perspective of Keiji Kiriya, a new recruit in the United Defense Force. Despite equipping its soldiers with powered exoskeletons, the UDF is losing its fight against the mysterious "Mimics", extraterrestrials which have laid siege to Earth. Keiji is seemingly killed on his first sortie after killing an unusual-looking Mimic but, through some inexplicable phenomenon, he wakes and finds that he has returned to the day before the battle. As this process continues, he finds himself caught in a time loop as his death and resurrection repeat time and time again. Keiji's skill as a soldier grows as he passes through each time loop in a desperate attempt to change his fate. After several dozen loops, he realizes his fate is similar to that of Rita Vrataski, a prominent ace who preferred to use a battle axe rather than a firearm. He uses his knowledge of the day to get close to her and her mechanic, from whom he gets a copy of her massive axe. He learns to use the weapon well; the boltgun that most troops are issued quickly runs out of ammo and jams easily. Realizing that he is a fellow looper, Rita confides in Keiji, telling him of the system the Mimics use: on death, they have the ability to send a signal into the past, allowing them to see the future and change their behaviour to avoid that fate. In each group of Mimics, there is one that acts as a central nexus that can cause the day to loop, as well as several antenna Mimics, all of which signal the loop to reset; Keiji became trapped in the loop as a result of contact with one such antenna. To escape as Rita once did, Keiji must first kill all the antennae and then the nexus.
