Description
Yuuto Suoh, a Japanese high school student, investigates an urban legend at Tsukimiya Shrine and activates a divine mirror while taking a selfie, transporting him to the world of Yggdrasil. Despite lacking innate abilities, he rises to become patriarch of the Wolf Clan. He leverages knowledge from his solar-powered smartphone to introduce Bronze Age technological advancements and military strategies inspired by figures like Alexander the Great and Oda Nobunaga. His leadership emphasizes meritocracy and diplomacy, rejecting executions in favor of subjugating clans through the ritualistic "oath of the chalice," which creates sworn familial bonds.
Initially kind but naive, Yuuto exhibits intense anger when confronting morally reprehensible acts. His early tactical successes include deploying phalanx formations to defeat the Horn Clan and coercing its patriarch, Linnea, into vassalage by threatening to burn her capital. He later employs innovative strategies like sleep-deprivation cavalry raids against the Hoof Clan and flood-based tactics to overcome the Lightning Clan's superior strength. His strategic growth evolves from historical imitation to context-specific solutions, such as war wagons to counter the Panther Clan's berserkers.
Yuuto maintains unwavering loyalty to Mitsuki Shimoya, his childhood friend and romantic interest from the original world. He contacts her regularly via smartphone; her research later reveals Yggdrasil's connections to Norse mythology, identifying Yuuto as Surtr and his clan as Fenrir. Despite persistent romantic advances from warrior maidens like Felicia (who summoned him), Sigrun, and Linnea, he initially rejects all proposals to preserve his relationship with Mitsuki. After a temporary return to the 21st century, Mitsuki insists on accompanying him back to Yggdrasil. He marries her as his first wife while accepting Felicia, Linnea, Sigrun, and others as concubines. They later have two children, Nozomu and Miku.
His personal conflicts include rivalry with Loptr, the disgruntled son of the Wolf Clan's former patriarch. Loptr murders his own father after Yuuto is named successor and later leads the Panther Clan against the Wolf Clan, employing magical berserker transformations. Yuuto also confronts Steinthor of the Lightning Clan, a dual-rune Einherjar initially perceived as a brute-force adversary but revealed to possess unexpected depth. A critical encounter occurs with Sigrdrífa (disguised as "Leafa"), the Divine Emperor of Ásgarðr, who provides insights about the mirror's magic. Her resemblance to Mitsuki causes repeated confusion; she later develops romantic feelings for Yuuto after kissing him for luck.
By light novel volume 14, Yuuto undergoes a transformative ascension, becoming an Einherjar and gaining supernatural abilities. His leadership philosophy matures to prioritize collective safety over personal desires, delaying his return to Earth to protect Yggdrasil's inhabitants. This resolve intensifies after Mitsuki joins him, committing him fully to unifying the clans against the looming threat of Ragnarök.
