The Master of Ragnarok & Blesser of Einherjar: Volume 3 by Seiichi Takayama

From weakest to strongest: A loser rises to become a sovereign!

As the patriarch of the Wolf Clan, Yuuto is now a figure of undeniable power and authority.

He grew as a person thanks to those around him, such as the warrior maidens Felicia and Ingrid. And in particular, there was a reliable, older brother figure...

In a world ruled by strength and the law of the jungle, just how did Yuuto come to be the sovereign ruler of the Wolf Clan? At last, the story will be told: The Master of Ragnarok's "Episode Zero"!
