Prime Minister Tsukasa Mikogami and six other world-renowned Japanese teenagers survive a plane crash and wake up in the Freyjagard Empire, a medieval realm of magic and beastfolk. Rather than panic, inventor Ringo Ohoshi and the rest of the group start applying their real-world expertise, treating the crisis as one more problem to solve. This manga adapts the light novel series, following the prodigies as they build, argue, and negotiate their way through a world that has no idea what it's dealing with.
