Not even my closest friends.So, when I was tasked with hunting Emma down and taking her life, it was just another day on the job. I couldn't have been more wrong. She's not like the others. She tangles with me without fear of the devil she might discover.Now, I find myself willing to challenge my darkest demons, or worse, unleash them—all for her. There's just one problem......

I read her words. I felt her soul. I knew she was destined to be mine.She's the light in the darkness, the epiphany of my redemption.I'll do whatever it takes to get my hands on her—though I'd rather her believe it was her own idea.So, I set the bait, luring her into making a deal with the devil.But surprisingly, she doesn't take it.And now, I'm left to force her hand.Because without her, I'm afraid I'll be devoured by the mo...

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 ...

To save both her own world and Japan, Menou must face off against Hakua, the very girl who created her. Just as it seems Menou and her allies will emerge victorious, however, Hakua manages to turn the tables and teleports herself, Menou, and Akari to a new world of her own design. In this idealized Japan, Menou experiences peace and material abundance for the first time in her life, while Akari and Hakua get to live a version of their high school days they could only have dreamed of. But t...

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.

Meanwhile, a mysterious entity that’s hidden in the Star Memory for centuries emerges, ready to enact a plan one thousand years in the making. Menou and Akari have managed to triumph over every challenge set before...

Menou on the run.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 overwhelm...

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. Genom Cthulha has left the Mechanical Society to set himself up in the ancient city. Does Menou stand a chance against an enemy even Master Flare couldn’t beat?

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...

Pandmonium in the mountains.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, bu...

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 h...

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. Meanwhile, the one of the Four Great Calamities begins to unfold in the undeveloped regions of the East and slowly inches toward them, leaving a trail of destruction in its wake...

Akari is back, and she's free of the Pure Concept Time. But she and Menou don't have long to celebrate their reunion. Pandæmonium has escaped her fog prison, and Hakua is ready to enact her plan. To defeat the twin threats of Evil and Ivory, Menou and the others must come up with a strategy capable of taking on two impossibly powerful foes. But are they prepared to make the necessary sacrifices?
