Well then, Rean. Let us dye the world in despair, the dismal end of the fairy tale.
He stays crouched in the darkness of twilight. With the glow gone, the curse spreads through the empire. His cannot express his regrets, no matter how deep his agony. Answers he will not get, no matter how much he asks. Unable to protect what was dear to him and doing what cannot be undone, he wallows in despair. Even his fate as a sacrifice he came to accept.
That is what remains of the Ashen Chevalier, Rean Schwarzer.
And the world has start to move toward its end. Erebonia, the greatest military state in history, overwhelms the world under the name of the Earth Dragon, Jormungand. In turn, the world tries it worst by playing it lowest trump cards to catch the dragon and decapitate its head. All while knowing that the black will attempts to fulfill their long-cherished desire through this conflagration and the snakes' aim in order to make their master's dream come true, resorting to any means necessary.
Grab them at their collars and make sure they understand! Is that "role" not one only we can fullfill!?
Those words rekindled the worn souls.
Erebonian Empire, Thors Military Academy's Class VII. Overcoming differences in social standing, nationality and joined by their juniors, together they are the "best" class. They rise against the demise. They walk tall in order to retrieve their light and their wings.
Well then, let's see it for ourselves: the end of this damn fairy tale.=== Plot ===
Prologue: "Changing World ~From the Bottom of Darkness~"
序章 変わる世界～闇の底から～ / Two weeks after the Gral of Erebos events, Juna Crawford, Kurt Vander and Altina Orion find themselves waking up from a coma in an unknown place. They learn this place is the hidden village of Elin, governed by elder Roselia and the home of the Hexen Clan. Also in the village are Original Class VII and Randy Orlando, from whom they learn the whole story of their escape from the Gral, their seperation from Musse, the situation surrounding Ash and how other students and collaborators managed to get away... except for, as everyone is painfully aware, Rean Schwarzer and Millium Orion.
Suddenly Juna remembers the exchange between Rean and Giliath Osborne. Following up on Kurt's deduction, Altina reveals that they are indeed father and son. Fuelled by anger, Juna desperately calls out to Original Class VII to get their friends back. Inspired by their classmate, Kurt and Altina then also voice their will and resolution. As if they snapped back to their senses, Original Class VII makes up their mind and get to action in order to rescue their dear friends. Rather than each going their own way, Original and New Class VII are determined to overcome the hardships as one united Class VII in the face of this adversity.
In the meanwhile, the Pantagruel, flagship of the Weissland Army, soars through imperial airspace. On board are General Aurelia Le Guin, Brigadier General Wallace Bardias and the Azure Abyss, Vita Clotilde, awaiting the arrival of their leader who appears behind them: Duchess Mildine Juzalith de Cayenne. While she prepares for the turbulence to come she places her trust in her classmates and smiles quietly.
Act 1 - Class VII's Trials
第I部 VII組の試練 / Act 1 8/2 | Together with Randy, Juna, Kurt and Altina are guided to the Saint-Gral Labyrinth by Roselia. In order to regain their former combat capabilities and stamina, they are thrown into a strict rehabilitation course. Determined to join up with Original Class VII's activities outside Elin, the three students enthusiastically engage in their training.
Making use of their crafts and Brave Orders, they make their way to the end of the labyrinth. There Roselia awaits them. In order to pass today's trial, they have to fight Roselia and, with Randy's support, endure the true strength of the vampire's True Ancestor. After the trial, Roselia informs them they finished the first round of their trial. Initially surprised that there was more to come, the students are determined to see their training through.
That night, Randy and Roselia join the students in dipping into the Fairy's Hotspring. The warm water and great company is doing wonders for the mind and body so they feel refreshed to continue their training the next day.
8/7 | After several days of training in the Saint-Gral Labyrinth, Juna, Kurt and Altina learn about the singularity points that have appeared throughout Erebonia via the investigations of Original Class VII and Roselia's visions. By sticking Wedges into the ground of these areas, they might be able to locate the stronghold of the Gnomes - and with it, the place Rean might have been captured. Set on this method, Original and New Class VII set off to find the singularity points. Before New Class VII's departure to the Sutherland Province, Roselia gives them their wedge and a pendulum to make it out of Elin.
After warping their way out of Elin through the Magic Forest, they wind up in Ishtmia Great Forest. They continue their trip out of the forest and eventually make it to Sutherland's provincial capital, Saint-Arkh. Using the temporary Bracer Guild in the apartment complex as their base, they start gathering information in Saint-Arkh's districts. The four are soon to notice the influence of the Great Twilight in the behaviour of soldiers and the conscription speed.
Upon returning to the guild house, they meet their Thors II schoolmate Kairi. After the Gral of Erebos events, Kairi tells he wound up in the area together with Tatiana and Pablo, and have started gathering information ever since. In order to track down more clues regarding the singularity points, they head to Parm to meet up with the other two students.
On their way, they find dark red Pleroma Grass growing on the former base they were stationed at during their first field trip. In one corner of the field, they find the Panzer Soldat Juna piloted during the Gral events and, independently, it attacks the Magic Golem that emerged from the Pleroma Grass. According to Roselia, who contacts them after the battle, they have become secondary contractors during the Gral of Erebos incident which may have inexplicably powered the Soldat. Reassured and with a new lead on the Pleroma, they resume their trip.
After arriving in Parm, they discover that the Vander Training Hall has been confiscated by the army and turned into a conscription office. They meet up with Pablo, who had been waiting for them in order to exchange information. In order to meet up with Tatiana, they would have to make way to the Titus Gate on the sourthern border with Liberl.
At the Titus Gate, they find the 1st Armored Division that was until now in charge of protecting Heimdallr. They find not Tatiana, but Rean's peer Margerita Dresden inside the resting area of the fortress. She tells them Tatiana was determined to find the person from the same club as herself, which was enough information for Class VII to settle on their next destination: the forgotten village of Hamel. On their way to the village ruins, they find Tatiana alongside the heavy armor Soldat, Hector. The path toward the village is riddled with Pleroma Grass and at the end, as expected, they find their classmate, Ash Carbide. Overcome with guilt and feeling unworthy to return to Class VII, Ash's argument is refuted by his classmates. Kurt's words in particular bring him back to his senses.
At that very moment, Ouroboros-deployed enhanced jaegers under command of Gilbert Stein show up. Ash tactfully launches a counter-attack, only to run into Zephyr's Rutger Claussell, Xeno and Leonidas. Impressed with his skills, they try to recruit Ash into their jaeger corps. He declines the offer and a fight follows. Rutger then summons Zector, the Palatinate Knight, which Juna and Ash piloting their Soldats manage to hold off. The jaegers leave the scene after Eliot Craig, Fie Claussell and Sara Valestein join the students as reinforcements.
Afterwards, the find the pendulum reacting and conclude this is the area they have to place the wedge. Randy decided to stay behind in the Sutherland Province with the students as Class VII, including Ash, makes their way back to Elin Village through the Spirit Path.
8/9 | Back in Erin, Class VII exchanges the information they have gathered so far in Roselia's atelier.
In absence of the ruler the Imperial Defence takes provisional control of the region, in several places conscription continues and new recruits undergo training, making the upcoming war so much more real. All these events stem originally from the Great Twilight, sped up by Chancellor Osborne and Governor-General Rufus Albarea's diplomatic prowess and charismatic peronality.
Through Ash they learn that Musse Egret, Aurelia Le Guin and Vita Clotilde are plotting something against the government. Allowing themselves one day of respite, Class VII sets off the following morning for the Lamarre Province, Musse's scheme still weighing on their mind.
8/10 | Travelling by the witches' monument once again, they arrive in the south of Avon Hill Country together with their Soldats. After concealing them, they cross the vast fields and wind up in the picturesque town of Milsante.
After asking around, they find fellow Thors II student Sidney at the local inn. He would be gathering intel on Leeves, so Class VII heads in the opposite direction to Raquel.
Despite his disguise most inhabitants of Raquel expressed their relief when Ash appeared before them unsceathed. As they gathered information, they ran into Thors II student Maya. Gustaf and Sandy had travelled further north to gather information in their hometowns. Class VII found their pendant responding to the northern region as well, so they followed suit.
Halfway through the valley they run into Gustaf. His hometown, the mining village of Aragon, had been completely mobilised for the production of weaponry.
