Summary
It's been a long ride, but Yuma and the Nocturnal Detective Agency are barreling towards the final confrontation with the Amaterasu Peacekeepers. After all the close calls they've suffered, all the betrayals and new friends they've made along the way... They're finally here.
The death threat hanging over Dr. Huesca will signal the beginning of the end. Our plucky heroes will have to dive deep into enemy territory to scrape at some of the secrets they're aiming to unravel and solve.
But the detectives won't be alone! They'll have the leaders of the Resistance backing them up this time, leading to quite the lively chaos in Amaterasu's research labs... Especially with familiar faces from the Peacekeepers stationed down there for the sole purpose of eliminating our heroes.
Yomi. Makoto. Dr. Huesca. Yakou. Vivia. Yuma. All of them have selfish motives in this penultimate Chapter. All of them have goals. Who will come out on top when the dust settles...? Who will be sacrificed?
When it comes time for the Mystery Labyrinth, the only thing Yuma can do is fight for all that he has left... It all comes down to this.

Summary
Yuma Kokohead was a cold, unfeeling Reaper. All that mattered was the job and his heart was a fortress of ice. He was the highest ranking Reaper aside from the original Grim Reaper themself in terms of retrieving souls on Death’s list, and he was happy with that. This was his role after all: helping souls move on. He was content that this would be his eternity.
So imagine his surprise when during one of his latest soul retrievals, a Werewolf by the name of Desuhiko Thunderbolt tumbled into his life, turning it upside down by slowly starting to melt those walls.
How will Yuma cope with opening his soul up again, and how will the other Reapers react to an immortal getting close to a mortal?

Summary
In the beginning, there was truly nothing but an empty expanse, and from that expanse, there, sprang aped, came the Machine Father, and the Earth Mother. Blessed were their spawn, that drew breath from wedded bliss.
But alas, as every mother should know, the Earth Mother underwent a labor so painful that the first hurricanes and thunderstorms drew from her howls of agony. But this effort bore fruit, as the Two became many more.
Blessed Amaterasu, bringer of Light and Hope, holy spawn of the Machine Father, Exorcist of the Past.
Blessed Tsukiyomi, bringer of stillness and simple joys, holy spawn of the Earth Mother, Keeper of the Past.
Alas, the two could never share the same sky, as different as the sun and moon. Not to mention the countless other kin that drew not long after.
And as for the Earth Mother, never the same again, her attitude became cruel and resentful. Nature, the paradise of humanity could no longer cope with the Machine. So her rage became the Yomi Deadlands.
The purgatory where the deceased get judged, and within the deepest layer, where demons and the Dark Mother resides.
But there is hope.
Hope, that resides in the Flame God, Kagutsuchi. -

Summary
Desuhiko is always at the agency and not because he wants to be! He’s waiting, always. And he’s getting more than a little fed up. He’s going to speak up and do something about it!
And while he’s at it he should probably also do something about Halara’s new habit of distancing themselves as far away from others as humanly possible.
Our resident superstar will ofcourse have no problems pulling this off!
