Yuuto's been sent to another world, where he is now commander, or "Patriarch" of a clan of warriors. To survive in this new world, he uses his cell phone, his only connection to the girl he loves back home.

To protect his new oath sister, Linnea, Yuuto leads the Wolf against the "Hoof" clan, their enemy. Things are going well for the Wolf when the leader of the Hoof strikes at Linnea's army, the weakness in their defenses.

Yuuto doesn't know what to do about the marriage proposal he's received from Linnea. To make matters worse, he gets marriage offers from two more girls, Kris and Al, who have come from the Claw clan just to be with him!

Yuuto visits a town that he's newly added to his domain, which was formerly run by the Horn. The people of the town aren't happy about their new ruler. Linnea tries her best to persuade them, but she's lost faith in her own ability to be a Patriarch.

Yuuto is faced with the powerful forces of the Lightning. They're unmatched in battle, and lead by an unstoppable leader. But Yuuto has a plan...

The war is over, and it's time for a vacation! Yuuto and the gang travel to a vacation spot, where all the girls fight over who gets the right to wash Yuuto.

Yet another powerful foe is after the Wolf. This time, it's the former brother of Yuuto, who was exiled for his misdeeds. Now he wants revenge...

Effy isn't getting along with the girls at school, and Kris has a plan to fix that. Meanwhile, Ingrid is annoyed that Yuuto fails to notice her advances, and tries to get him to realize that she's a girl.

Leafa, a girl who looks just like Mitsuki, give Yuuto a clue how to return home. The Wolf enjoys a New Years party, only to learn that the Lightning is on the march once more.

The Panther launch a surprise attack, catching the Wolf off guard. Yuuto is forced to show if he truly has what it takes to be the Master of Einherjar.

Yuuto is sent back to modern Japan, where he's forced to make a choice: stay there with his beloved Mitsuki, or go back to save everyone.
