Although it appeared as if Kissing was defeated by Mei, she stands up again. Lord Mask and Risya, Growley and Nameless are also fighting one another, equally matched. As the back-and-forth battle continues at each location, Talisman reports that he has achieved his goal and is about to leave. Iska wants nothing more than to settle their fight, but an atrocious astral power approaches...

Alice’s hatred towards the Empire grows stronger after their recent attack, when Iska, in pursuit of Vichyssoise, appears in front of her. They can no longer maintain their easy relationship as a friendly rival. With ruthless determination, Alice declares war on Iska, regarding him as an Imperial swordsman, hostile towards the Sovereignty. Meanwhile, a man watches their battle and sighs... Salinger the sorcerer had also followed a similar fate as the two.

Alice is forced to kidnap Iska. Afraid of what will happen to him if word gets out, Alice orders Rin to take them to the Prison Sector to decide their next move. Meanwhile, the members of Unit N07 infiltrate the Sovereignty to get Iska back.

Iska and Mismis survive the eruption of the vortex, but the team doesn't escape unscathed. Meanwhile, Alice decides to go search for Iska in Ein again. They are reunited by fate, but everything is jeopardized when Rin makes a big miscalculation.

After their fateful encounter, Sisbell visits Iska at the hotel and asks for his help, ironically offering a similar deal as her sister Alice once did. However, before they can discuss the matter in great lengths, Sisbell is targeted by one of her own.

Iska arrives just in time and battles Salinger, who not only wields multiple astral spirits, but can also combine two contradicting elements together to make his astral art even stronger. Can Iska measure up to him and defeat him?

Iska begins with the plan to infiltrate Hydra's base to rescue Sisbell.

Two nations, the Empire and the Nebulis Sovereignty, have been at war for 100 years. Imprisoned for freeing a witch, Iska is given a chance at freedom. In exchange, he must take down a powerful astral mage known as the "Ice Calamity Witch."

Joining forces with Alice, Iska and his team quash the Empire and the Sovereignty's conspiracy and successfully protect Sisbell. After the ordeal, they travel to Alsamira to enjoy their vacation. However, Sisbell has not returned to the palace yet, and asks Unit N07 on vacation to escort her back, offering something they can’t refuse. Meanwhile, Alice gets a gut feeling that Sisbell's new bodyguard might be Iska...

100 years ago, a drift of astral energy created a vortex which cursed, or gifted, people with astral power. Now another vortex has formed, triggering a race between the Empire and the Nebulis Sovereignty to acquire it.

Iska sends Miska and the others away to safety and faces Mizerhyby himself. Soldiers with their attack power significantly enhanced by Mizerhyby’s astral power, “Glory,” targets Iska. At the same time, Salinger also shows up in “Snow the Sun.” Vichyssoise attempts to intercept him, but... Will Iska and the unit succeed in rescuing Sisbell in the midst of all the chaos?

Alice is back in the central province and reports to her mother about Sisbell's whereabouts. Sisbell herself also returns to the central province a short time later. However, upon her arrival, there is a surprising encounter.

Iska and Alice suddenly meet again at the Riesbaden station. Alice then learns that he is the bodyguard for her sister Sisbell. Meanwhile, a major incident occurs in the central province.

Unit N07 gets a lucky break; they're given a forced leave of absence for 60 days. They decide to visit a tropical resort to camouflage their attempt to figure out a game plan for Mismis' astral crest. However, fate has something else in store for them.
