A television anime adaptation of author Seiichi Takayama and illustrator Yukisan's The Master of Ragnarok & Blesser of Einherjar ( Hyakuren no Haō to Seiyaku no Valkyria ) light novel series has been green-lit. The staff also opened an official website and Twitter account for the anime.

Kōsuke Kobayashi ( Idol Time PriPara , Alice or Alice ) is directing the anime at EMT Squared. Natsuko Takahashi ( ATASHIn'CHI , Romeo × Juliet , Love Tyrant ) is in charge of the series scripts. Mariko Ito ( Log Horizon , ViVid Strike! , Love Tyrant ) is adapting the character designs for animation, and is also credited as chief animation director alongside Miyako Yatsu ( Say "I love you." , Flowers of Evil , DIVE!! ).

J-Novel Club licensed the novels and is publishing them digitally. It describes the story:

Some urban legends are best left untested! Yuuto Suoh gets more than he bargained for when he joins his childhood friend Mitsuki Shimoya in testing out an urban legend. When he uses his phone to take a picture of himself with the local shrine's divine mirror, he is whisked off into another world – one heavily steeped in the lore of the old Norse myths. Using his knowledge gained from school and from his solar-powered smartphone, he has the chance to bring the Wolf Clan, the same people who cared for him, to prominence, all while earning the adoration of a group of magic-wielding warrior maidens known as the Einherjar.

Hobby Japan began publishing printed novels for the series in August 2013. The company published the 14th novel volume last November 1. Chany is drawing a manga adaptation on Hobby Japan's website, and the company shipped the third compiled volume last June. The bilibili booth at the AnimeJapan 2018 convention will host a stage event on March 24.
