RADIANT

Seth returns home and tells Alma of his encounter with the mysterious man during his battle with Konrad, but Alma isn't buying it.

Seth sets out for the capital but gets intercepted by a Merchant-Baron airship. Seth barely escapes thanks to Grimm, and successfully reaches the capital where he encounters Doc and Melie.

Seth runs into Melie and Doc, but Melie is cold toward him and quickly leaves. So Seth heads to the castle to look for clues about Radiant, but he's turned away at the gate. Then he encounters a myserious old man named Myr who leads him to the Knights-sorcerers' stables. There he meets an aspiring Knight-sorcerer named Ocoho, who's preparing to set out on a mission to defeat a Nemesis. Seth is...

When the battle threatens to ruin farmland, Seth does his best to protect the crops. Ocoho is impressed and casts defensive magic to help him, but she's reprimanded for going against orders. But then Queen Boudica appears and praises Ocoho for protecting the land as the legendary sorcerer Merlin did. The farmers also say that a spirit called the Dullahan started appearing in the area around the...

Seth visits Melie at the inn where she's staying, but she treats him coldly. Seth had left Artemis on his own because he didn't want to hurt his friends with the power he couldn't control, but Melie wanted Seth to have faith in her as his friend; the two of them just can't see eye to eye. Seth is left with nowhere to go, but then Ocoho asks him to train with her, offering to look in the castle...

Ocoho's search for information on Radiant isn't going well, so Seth makes up his mind to sneak into the castle archive himself. For some reason, even though he's never been inside the castle before, he feels as if he knows it. He takes a hidden passage he'd seen before in his dreams, and beyond it, he sees a Nemesis and a young man. The young man reacts with fear upon seeing Seth's horns and...

A Nemesis that looks like Seth has appeared, brought forth by a mysterious man who lurks deep beneath the castle. He is the one who has been making the Spectre Nemesis appear. After making his way beneath the castle, Seth was attacked by a Nemesis and blacked out, finding himself trapped within the realm of his own consciousness. He comes face to face with his memories, which causes him to...

The mysterious man, who claims to know Piodon, is terrified of Seth's out-of-control form and ends up being blown out of the castle. When Seth disappears, Melie, Doc, and Ocoho follow traces of Fantasia to find him, but they end up in a forest that no one has ever escaped after entering. As they make their way through the forest, they find Myr and his wife Jill, who have been protecting Seth....

Ocoho and Melie are blamed for disobeying orders in the previous battle, but Mordred saves them by telling the queen that it was all Lord Brangoire's mistake. Seth, meanwhile, remains in Caillte's forest, training so that he can learn to control his power. With the help of Myr and Jill, he learns how to harmonize with Fantasia, but when he tries to control the darkness inside him...

Led by Lord Brangoire and Lord de Gulis, the Knights-sorcerers set out to battle a Nemesis that has appeared in the surrounding farmland. Ocoho is the only one who notices that the enormous Nemesis is actually a composite of several Echo Nemesis, which then split apart and begin rampaging as countless individuals. Ocoho calls for help, but no one can hear her, and she's left with no choice but...

Seth is still unable to control his rampaging power. He tries to suppress it by force, but only ends up closer to being completely engulfed by it. But by thinking about all the bonds and relationships he's forged up to this point, Seth experiences an awakening and learns to use his power to create rather than destroy. He also learns that if he can use his power of creation correctly, the world...

As the town bustles in preparation for the upcoming ordination ceremony, Ocoho leaves quietly, avoiding being seen. Lord Brangoire grows suspicious of her behavior and attacks her. Melie stops him, but is shocked to see Ocoho starting to call forth a Spectre Nemesis. Seth stops Ocoho when she appears to go on a blind rampage, but when she returns to her senses, she doesn't remember anything...

Dragunov and Liselotte meet with Doussant of the Merchant Barons, who proposes an alliance that could help the Inquisition that would mean the neutralization of Fantasia. Meanwhile, Ocoho seeks the truth about who is using her curse to make the Spectre Nemesis appear.

The ordination ceremony has been called off. Queen Boudica refuses to surrender and leads her forces in a do-or-die resistance. The Knights-sorcerers charge into battle, but they face a crisis when they lose the ability to use magic due to the strange machine supplied by the Merchant Barons. Meanwhile, Seth finds Diabal again underneath the castle, and Diabal tells him they are something like...

Diabal started cooperating with the Faithful of the Hermit in order to escape Piodon's pursuit and protect his hiding place. Through the realm of consciousness, Sidh, Seth learns that a war has broken out above ground. He hurries back to the surface, but Melie is caught by Dragunov as bait to lure him. Meanwhile, Ocoho leaves the battlefield to follow Mordred and Sagramore... only to find them...

Mordred is revealed to have no emotions. He had infiltrated Caislean Merlin as a child and spent his life there creating chaos in anticipation of this day, all on his father's orders. His father, Baron Doussant, has been working toward the goal of making all infected people into slaves. Back on lang, Queen Boudica flies into a rage and attempts to destroy the machine that's negating Fantasia,...

Dragunov had been told by General Torque that capturing Seth was his only objective, and that a military intervention was not his wish. But even after Dragunov reports that he has Seth, the Inquisition warships begin to bomb Caislean Merlin. Dragunov defies orders to join his former squadron and try to stop the war. Meanwhile, Seth takes on Santori, but is overwhelmed by his immense strength....

The mysterious knight turned out to be Doc trapped in a suit of armor along with several memory stones. The soldiers race to rescue the queen, but Verone's petrifying ability impedes them. Santori attempts to have some fun in his battle with Seth and ends up causing him to go berserk. Santori then talks about using people as if they were tools, causing him to explode with rage. Ocoho and Melie...

Cornered by Ocoho, the Merchant Barons show their true colors. It seemed this would be the end of the battle, but the when the Inquisitor Ullmina learns that Santori has been lost, she has an even more powerful Harmonizium dropped into the forest. The Fantasia there begins to disappear, and the soldiers under the control of Ullmina's powerful miracle close in on the castle wall. Seth hurries to...

Engulfed by despair, Myr sets out to on a rampage to destroy everything. Seth responds to Myr's rampage by flying further out of control, and ends up captured by Ullmina. As the biggest crisis yet closes in, Ocoho grills the disheartened Queen Boudica on who she truly is. Encouraged by Ocoho's words, Queen Boudica gets back on her feet to destroy the Harmonizium. With the help of Grimm and...

The thing that finally stops Myr's rampage is a memento Seth found, left behind for him by Jill. Seeing new life growing before him, Myr finally finds hope again. After beginning to question the Inquisition's intentions through this war, Dragunov returns to Bome to question General Torque. The long battle is over. All the people of Caislean Merlin gather as Queen Boudica declares an end to old...
