After the destructive damage caused by Zerg's Shelther and their fellows, Abyssals, the Earth again felt back to the darkness age of mankind civilization. 

​

    With so much difficulties ahead, the protector of the Earth, Kanmusumes would not choose to give up so easily; by teaming up with spiritualized elite Terran combat and supportive units, they decided to rebuild the world again.

​

    Still, the reason of spiritualization could still keep stable remains a big mystery. According to Karax's research, Void Energy should be the essential matter to sustain such phenomenon, so there was no one can explain why for now.

​

    As they rebuilt the broken world brick by brick, a brand new editable, multi-purpose resources, "curry" was found at the same time, treating as the crucial key to regain the lost technologies during the war of Zerg's Shelther.

​

    However, this curry seemed to be discovered and gathered by a strange group of yellow "penguins", who were believed to live in the underground world for numerous years.

 

    The underground world beneath the solid they stand, had a name called "Netherworld", a place where demons live.

​

    The seemed-to-be destined meet with these demons, Kanmusumes and Terran were all understand, there would be a storm coming very soon...

    Chaldea Security Organization, an organization which has it's 

duty for restoration of Human Order, extending the future of mankind.

​

    On the recent Grand Order, an unexpected error during Rayshift leaded to master Ritsuka to land on a mysterious place where no records in the Chaldea's database.

​

    Ritsuka is a Magus who is capable of giving command and controlling the Heroes and Heroines, who are spiritualized as 'servant' in their current summoned space.

​

    After accidentally stepping into this unknown place and losing the contact with Chaldea, Ritsuka must first build up the outpost to figure out the situation; even her best comrade, Mash was not on her side, so Ritsuka ended up with finding out the solution on her own, but at least she realized that she might be able to look for the help from locals.

​

    A young country girl, Shallotte, who ran a local atelier with her Alchemy, showed herself in capable of helping out this foreigner girl with her full hospitality.

​

    However, after seeing the receipt written by Ritsuka, Shallotte seemed to know that things got a little bit out of her expectations.  

​

    "Servants? Holy Grail War? I can not even image that there's still something pretty much worse than the 'Dusk', oh I guess I'm into this thing for sure, right?"

 

    The counterpart by exchanging the information, they knew they were going to face and try to solve the utmost, distorted, upcoming chaos together, or it would no more be something capable to be solved by a single treasure, Holy Grail.

 

    "Perhaps the 'Dusk' you mention here might be the key to cause the instability of Rayshift, and for me what I'm going to say is, the overture of the Holy Grail War, it had already begun..."

    In the year of 2050, after the fallen of Amon, another unexpected ancient enemy, was waiting for bringing the great disaster to the entire universe, once again.

​

    But this time, their ambitious conquer might be not for the sake of ruling the world, but seeking for a salvation, and an answer they were eager to know for centuries.

​

    Artanis, Hierarch of the Daelaam, noticed an unstable reaction of Void Energy on the planet called "Earth", and this may be the first time he and his Templars traveled here with their gigantic spaceship, Spear of Adun.

​

    As the time they sent some Probes for investigation, a sudden eruption of Void Energy just made the time and space itself into a huge distortion, making multiple universes connected with each other.

 

    Everything just happened too fast, when Artanis and other warriors with him, opened their eyes again, they just found out they changed into young human girls without any warning.

 
​    Karax, the phasesmith, told Artanis that the phenomenon they saw here is called "spiritualization", which would change their physical appearances with enhanced combat ability.

​

    "The actual and direct reasons to made such things happened must be found out." said Artanis.

​

    To find out the answer behind spiritualization, Artanis had to seek for other lost Kanmusumes on the planet Earth, and help they to defeat their feuds, the Abyssals.

​

    How would Artanis and other people make use of the power of spiritualization? And what was Abyssals actually looking for? The answer would only be found as they kept moving on...

Two enemy forces that threat human kind for years: Neuroi and Abyssals, has put their lives in to great danger and might bring the extinction of human. 

​

In order to stop them from bringing more destruction to innocent people, the 501st Joint Fighter Wing has their allies contract to share both sides technologies and combat skills:

Kanmusumes gonna learn how to enhance their anti-air capacity by learning magic system, and Witches will need to face the problems from submarines and other water-borne Neurois with the help from Kanmusumes.

​

However, the evolution from Neurois was faster than they can image, the secret for their unexpected evolution may be hidden in the alliance of these two powerful foes...
