Hyakuren no Haou to Seiyaku no Valkyria

Hyakuren no Haou to Seiyaku no Valkyria thrusts Yuuto Suou out of ordinary life and into a realm shaped by Norse-inspired myths, clan rivalries, and a brutal code where strength decides survival. While testing a shrine's divine mirror with his childhood friend Mitsuki Shimoya, he snaps a photo beside it and is suddenly dragged away from home, left to rely on the lessons he picked up at school and the solar-powered smartphone in his pocket. In this unfamiliar world, Yuuto becomes connected to the Wolf Clan, the people who take him in and help him navigate customs, alliances, and the constant pressure of living among warriors. The Einherjar, formidable warrior maidens, are both dangerous allies and a source of tension as he learns how to turn modern knowledge into practical advantages. As Yuuto earns his place in the clan, he must balance survival, shifting loyalties, and the bonds that matter most, because every choice can alter his future in this hard-edged land.
