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. – ANN

Episode 1 Summary: It’s been two years since Yuuto was accidentally whisked away to an unknown bronze age society, but in that time he’s managed to become the leader and patriarch of a powerful clan. His goal isn’t exactly to gain control of the entire land, though that might be the unintended consequence; he wants to bring about peace to its various warring groups so that he can then concentrate on finding a way back to his native time and place. Luckily Yuuto still has the use of his smartphone, as it gives him access to military tactics and other knowledge he’s able to utilize to gain an advantage over almost any adversary. His most recent victory is over the Horn Clan, and the leader chooses to become his “sister,” a term for a subservient position beneath the patriarch. Soon after their alliance is solidified, another group makes moves to attack the Horn Clan’s homeland. Though the ink is barely dry on their alliance, Yuuto chooses to honor it by sending his armies to aid his new subjects.
