The Encounter of the Two Nations' Ultimate Weapons

After their brief but fateful encounter, Iska and Alice made an impression on each other, resulting in some sleepless nights. Despite being on the opposing sides of the war, they soon learn that they have much more in common than they thought.

Iska is given a new mission to apprehend the Ice Calamity Witch. By accomplishing the mission, Iska will be a step closer to realizing his dream for a peace treaty. When Iska and Alice meet again, they weren't prepared for what was coming for them.

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.

The members of Unit N07 successfully locate the vortex, but the Sovereignty had already found it. After Mismis is captured, Iska must fight against Kissing, a purebred, to get her back before the Empire attacks the Sovereignty base.

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.

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.

With Risya's help, the Transcendent Demon, Salinger, has escaped from his 30-year imprisonment inside Ollelugan Prison Tower. His unique astral spirit makes him incredibly dangerous to any astral mages, but Alice and Rin must step up and try to stop him.

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?

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.

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.

The Empire's experimental weapon, Object, goes after Sisbell. It also detects Mismis' astral energy. Iska and his team must fight Object to save Sisbell and to stop it from uncovering Mismis' secret. However, it seems Object has gone through an upgrade.
