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.

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.

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.

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.

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.

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."

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.

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.

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?

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.

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...

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.

The suspect who attempted the assassination may target Sisbell next, since she hosts an astral spirit with the ability to reenact the past and identify the suspect. Unit N07 goes on high alert and is left with no other option but to hide at a hotel and wait for an audience with Mirabella. However, a large explosion occurs near the hotel. When Sisbell tries to reenact what really happened, someone with the same "shadow" from the reenactment starts to attack her.

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.
