The Master of Ragnarok & Blesser of Einherjar (Original Japanese Version)

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.

Yuuto cozies up with Felicia and the others underneath his new kotatsu. Later, things heat up between Yuuto and Ingrid.

In the 21st Century, Mitsuki's friend, Ruri, takes her to her cousin, Saya, hoping that her knowledge of mythology might help them find out more on where Yuuto is.

The girl who resembles Mitsuki claims to be Leafa of the Jarl Clan and Yuuto takes her to the Wolf Clan's palace. However, she is soon revealed to actually be Sigrdrífa, the Divine Emperor of the Holy Ásgarðr Empire, the ruling power of Yggdrasil.

Out of ideas, Yuuto decides to face the Panther Clan head-on and inspires his men with a rousing speech, but is it all in vain?

Yuuto returns home and reunites with Mitsuki, but he can't stop thinking of Yggdrasil and the time he spent with Felicia.
