Set in a post-apocalyptic world called Alcia, Hina Farrow is given an enigmatic orb called a Ballot containing the number 10000 by her mother Tsukina, who urges Hina to find a Legendary Ace. Tsukina is then dragged into the Abyss after her Count has reached zero. After searching for five years, Hina travels from her hometown of Fieni to a public foot bath in Irinis, where she meets Licht Bach, first appearing as a masked pervert. Licht is shunned by his boss Nana Bassler, owner of a mobile taver
Three centuries ago, the seven Legendary Aces ended the Waste War with their superhuman abilities, but they vanished thereafter. In the present, Licht uses his superhuman speed, in which his footsteps can crack the ground. Meanwhile, Nana mentions that Licht is nicknamed the Ace of Flashing Strikes, even though the number -999 printed on the back of his left hand represents the number of times that he has been rejected by women. With Hina in tow, Licht does a supernatural leap into the sky above
Hina is relieved when Nana informs that the Alcian Royal Army has started distributing wanted posters of Licht, believing that he is currently holding onto Hina's Ballot. A sergeant major named Lynn May and her subordinate named Pele Poporo are stationed in a peaceful mountain village called Homhough. It is revealed that Lynn's Count on her uniform represents the number of times that she volunteers to help people. After Pele shows Lynn the wanted poster, Lynn encounters Licht wearing a pudding c
Lynn expresses her despondence to Pele over having lost a potential promotion as a second lieutenant. When Licht suddenly appears, Lynn chases Licht throughout Homhough, leading the villagers to believe there is a lover's quarrel. Licht then makes a clean getaway when Lynn complains about the miniskirt of her uniform. Saying that the mobile tavern must be rebuilt, Nana hires Hina as her employee. Distracted from chasing after Licht, Lynn is bombarded with requests from the villagers. Admired by
Inside the iron barrier, Licht and Jail engage in an intense battle, as Jail's iron manipulation is strengthened by his convictions. Licht surrenders after being confined to iron restraints conjured by Jail, who deduces that Licht was a former soldier in the Alcian Royal Army based on his hand-to-hand combat techniques, though Licht refuses to answer. When Jail proceeds to torture Licht with an iron chain, Lynn shields Licht and gets injured in the process. Jail berates Lynn for ignoring her off
Hina and Nana finally find Licht in the grassland. Nana says that Jail has set up roadblocks all over Alcia due to the incident in Homhough, while a jealous Hina scolds Licht for leaving her behind. Licht is forced to save a woman named Pelmo from falling to her death in an experimental human-powered aircraft resembling a steel bird. Bringing them to her shed, Pelmo asks Licht and Hina to help make her dream of flight come true, even though aviation research is a crime punishable by death. Licht
In a tent, Licht wakes up and prepares to leave, but he reconsiders when Hina asks him to stay during her somniloquy. Licht and Hina visit a town square, but Lynn and Pele spot them. Lynn tries to arrest Licht not long before thanking him for saving her life in Homhough. After Hina and Lynn swap stories of how they met Licht, Nana hosts a cooking competition for Hina and Lynn with Licht as the prize. Lynn cooks a sweet-smelling cream stew using various vegetables, while Hina cooks a deadly-smell
There are no survivors in Linden, and its lake has been swallowed by the Abyss. An injured soldier arrives and claims that a fire-breathing demon came from the Abyss and destroyed Linden. While Jail does not believe this story, Lynn and Pele take the injured soldier for treatment in Anesis, where they find Licht, Hina and Nana. Before Jail starts confronting Licht on what he knows about the demon of the Abyss, Nana suggests for Licht and Jail to play a drinking game. Jail drunkenly accuses Licht
As the helicopter gunship attacks Anesis, Jail shields everyone with an iron wall, which is then destroyed by a missile. Jail becomes confused when Licht reveals that he was a former colonel in the Alcian Royal Army. The townspeople begin to evacuate as Licht draws attention to the helicopter gunship, but he is stopped by Althing, the long black hands that emerge from the Abyss. While trying to grab the helicopter gunship, Althing is attacked by Licht, who is repeatedly electrocuted as a result.
A Star Stake commences in an all-or-nothing showdown between Licht and Mizuka. Despite being shot several times by Mizuka, Licht succumbs to his bloodlust, releasing a powerful aura and raising his Count to 57000. Licht moves at untraceable speeds with his shockwave blasts, overwhelming Mizuka. Nana finally reveals that Licht has been taken over by an alter ego who will only stop when he collapses from fatigue. Licht defeats Mizuka, whose Count drops to 16000. Having also been under the influenc
As Licht, Hina, Nana, Lynn, Pele and Mizuka recover in a cottage, Althing has not left yet since the Star Stake between Licht and Mizuka remains deadlocked. Much to Licht's amusement, Lynn, Nana and Mizuka are harassed by Althing due to their large busts, unlike that of Hina. Meanwhile, Jail is summoned to the royal capital of Neue Welt, the main headquarters of the Alcian Royal Guard, where he meets supreme commander Alexandrov Grigorovich, his doting adoptive father. Alexandrov informs Jail th
Hina, Jail, Lynn and Pele enter the academy and try to find out how to change the past. They are soon confronted by Taketora Doan, but Jail is left defenseless without his black gloves, while Mizuka and Tokikaze Sakai try to stop Taketora. However, a rivalry is sparked between Jail and Tokikaze. During the entrance ceremony, captain Alan and second lieutenant Firenda explain that Japan is the only country left after a world war, revealing that the academy is the 13th Special Military Forces Scho
Hina, Jail, Lynn and Pele decide to enroll in the academy, in which Schmerman will take the place of Alan to personally instruct the students. Alan previously overheard Hina, Jail, Lynn and Pele talking about Alcia in the school library. Schmerman says that the every student will receive two stars, in which they will graduate with extra food rations after collecting ten stars and they will face expulsion after reaching zero stars. After it is explained that stars can be earned by performing task
When Rihito is suspected of peeping in the women's bath, Saki and her friends Asumi Sumitani and Kyouka Narimiya catch Rihito in the act after Pele switched the bath entrance signs, leading Jail to accidentally enter the women's bath instead of the men's bath. Since Alan technically caught Rihito in the end, the students are forced to survive in the woods together. When Rihito purposely knocks Saki, Asumi and Kyouka into a river, they decide to abandon their embarrassment like disciplined soldie
As Jail realizes that Alan is actually a young Alexandrov, Alan deduces that Nana is trying to change the past which will alter the future. The next day, Alan escorts Hina, Jail, Lynn and Pele to a suburban area full of starving residents, demonstrating that there is no practical way to feed everyone. In the school library, Hina, Jail, Lynn and Pele remain undecided since the existence of Alcia was spawned by Licht winning the Waste War. After the students become exhausted from jogging around a
Jail tells Hina, Lynn and Pele that they must not stop Rihito from undergoing the Ace procedure by Firenda in the laboratory. Taketora claims that Mizuka is a weakling and proceeds to steal her remaining star before leaving. However, Jail ends up giving up one of his two remaining stars to Mizuka after advising her to have conviction. Lynn confides in Pele that she loves Licht. Hina and Jail both believe that Alcia will still exist if they allow Rihito to become Licht but have him remain nonleth
Rihito survives in the nick of time when Jail manages to start up the backup generator. Schmerman gives Rihito an ōdachi, explaining that is it a Replica of a Ballot activated by a Count of his choosing. Rihito defeats the Joint Force with his superhuman speed, earning him the nickname the Ace of Flashing Strikes. The Joint Force sergeant then reveals that a nuclear bomb is implanted somewhere inside the academy and the detonator is hidden somewhere in his body. Left with no other choice, Rihito
Nana narrates the story of the Waste War. Rihito became Licht and single-handedly slaughtered thousands of enemy soldiers, eventually hiding his face behind a mask. Tokikaze, Taketora, Mizuka and Alan later qualified to undergo the Ace procedure. Schmerman told Alan and Firenda that the world is beyond saving. Rihito eventually went berserk and severed Mizuka's left arm. Two years after the Waste War ended, Schmerman, Alan and Firenda collected the seven Ballots, using them to create the utopia
Nana celebrates the return of Hina, Jail, Lynn and Pele with some drinks on the house. Mizuka cautiously watches the party from afar. Hina decides to drown her sorrows since Licht turned her down due to the apparent age gap. Realizing that Nana also has unrequited feelings for Licht, Jail punches Licht in the face for being oblivious. The memory card contains recordings of a young Nana documenting about how she felt about Licht for the past 300 years. Licht feels ashamed that he lost his smile a
Tsukina was Licht's childhood friend who survived for 300 years without being surgically altered and stole a Ballot from the Special Services Unit five years ago, which left Schmerman with only three Ballots. Moreover, Tokikaze was Hina's father whom Licht previously murdered. Hina, Nana, Lynn and Pele all pass out from wine drugged by Licht, who plans to defeat the Special Services Unit on his own. However, Jail is immune to the wine drugged by Licht. Alexandrov is informed by his secretary Eri
Hina, Nana, Lynn and Pele find an unconscious Licht at the Dead City of Hoffnung before they are surrounded by the Special Services Unit. Meanwhile, Jail interrupts Alexandrov during his lunchtime and challenges him to a Star Stake. Easily melting Jail's iron devil, Alexandrov reveals himself as the Ace of Explosive Strikes. In the past, Alexandrov was a soldier in a small village, where he was a father to an eight-year-old son and a three-year-old daughter. When the children were later murdered
When Lynn manages to flee on horseback, Taketora uses gravity telekinesis to shoot debris through her torso, gravely wounding her. Taketora agrees to wager the lives of Hina, Pele and even Nana on the certainty that Licht will return by sunrise. Lynn finds the unconscious Licht at the Dead City of Hoffnung and attempts to perform cardiopulmonary resuscitation, but she begins to pass out due to blood loss. She is saved by the arrival of the Homhough villagers, including Avsayette "Greengrocer Lad
Schmerman wonders how Licht will pit against Mizuka and Taketora. Licht is blamed for unforgivably causing Mizuka to go berserk and for his former classmates committing suicide to honor his dream of a nonlethal army. Before succumbing to his bloodlust, Licht is stopped by Jail, who offers to fight alongside him. With his Count reduced to one, Jail can only summon a single piece of iron, but it serves enough to block all of Mizuka's shots. Jail renders Mizuka psychologically incapable of finding
Licht awakens in the world of darkness, where floating masks belonging to Taketora, Alexandrov, Mizuka, Tokikaze, Nana, Licht himself and even Pele try to convince him to give up pursuing the impossible dream of a nonlethal army. Although he eventually accepts himself as a murderer, Licht regains the motive to come back to his friends. He successfully destroys the masks and pierces through the world of darkness, bringing him back to the real world. After Licht knocks out Taketora, a flashback re
