The Executioner and Her Way of Life

The Lost Ones are wanderers who come here from a distant world known as "Japan." No one knows how or why they leave their homes. The only thing that is certain is that they bring disaster and calamity. The duty of exterminating them without remorse falls to Menou, a young Executioner. When she meets Akari, it seems like just another job...until she discovers it's impossible to kill this girl! And when Menou begins to search for a way to defeat this immortality, Akari is more than happy to tag along! So begins a journey that will change Menou forever...

Journey to where the fog never lifts… Libelle, a city by the sea. Those who venture into its fog are said never to make it back alive—a murderous phenomenon that’s another of the Four Major Human Errors that has ravaged the world. But for Menou, it just may be the solution she’s looking for. To fulfill her role as Executioner, she needs to find a way to murder Akari, the girl who seems to spring back to life whenever she’s killed. Maybe this time, Menou will be successful in carrying out her duty.

To kill Akari, Menou scours the outer reaches of the West in search of a legendary blade that turns all it touches into salt. There, she stumbles across Sahara, a monk, who has history with the young Executioner and begs her to take her life for reasons unknown.

Hoping to avoid a future where Menou dies trying to save Akari, the girl from Japan runs away with her sworn enemy, Momo. The pair ride the rails to a secluded village in the mountains where they believe they’ll be safe for a few days. Unfortunately, they’re not the only ones who decided to stop off there. Manon and Pandmonium have arrived as well, and they aren’t alone. Akari had hoped keeping away from Menou would be enough to spare the girl she holds dear, but keeping the Executioner alive may require a more drastic course of action.

Menou sets out after Flare, determined to take back Akari. If Akari must die, Menou is determined to be the one that kills her, at the very least. To do so, Menou must seek the Sword of Salt—a difficult task even without a time limit. Still, the Executioner is determined to triumph and surpass her former teacher, no matter what taboos she must commit...

The duel with Master Flare in the land of salt continues. Menou should have the upper hand now that she’s linked with Akari and her immense supply of Guiding Force, yet reality suggests otherwise. Master Flare still has a few secrets up her sleeve, and she’ll do anything to win.

Half a year has passed since the battle with Master Flare. In the time since, Menou has become the most wanted person on the continent, evading the Lord’s Executioners at every turn while hunting for a way to restore Akari. Her search brings her to the north and the Starhusk floating above. The bizarre creation could make for a powerful weapon against Hakua, but Menou will have to reach it first. And to do so, she’ll need to get past the Inquisitor Michele, whose overwhelming power is strikingly similar to that of Archbishop Elcami...

Long-buried secrets. Menou and her group venture deep into the City of Ruins to reach the Astrologer, who controls the Starhusk. Instead of finding the ultimate weapon to defeat Hakua, they discover a lost one who should’ve died a thousand years ago. And she’s not the only one hiding below.

Menou and her group finally acquire the Starhusk, their best chance to defeat Hakua, but at the same time, they lose their means of escape. With Michele on the way, will they have enough time to properly activate the Starhusk? In the deepest reaches of the last Human Error, Menou must make a desperate choice...
