Arisa Date

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.

When Narumi, an office lady who hides the fact that she is a yaoi fangirl, changes jobs, she is reunited with Hirotaka, her childhood friend who is attractive and skilled but is a hardcore gaming otaku. They decide to start dating for now, but being otaku, both of them are awkward so a serious romantic relationship is rather difficult for them...
