The English-language film tie-in edition of the novel also uses this title. The novel was Sakurazaka's breakthrough science fiction novel, earning wide praise from fellow novelists including Yasutaka Tsutsui and Chōhei Kanbayashi and was entered in contention for the Best Japanese Long Work in the 36th Seiun Awards in 2005. Plot 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 , extraterrestrials who 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.
