Years ago, humanity almost got wiped out by huge magical armored insects that had become too strong and aggressive to handle. Because of these giant bugs, humans do not live on the earth anymore, but in floating cities instead. However, this does not mean that everything is lost, because the wizards from prestigious floating wizard academies are fighting these monsters. Kanata Age is a young man now labelled as a traitor even though he was once praised as the Black Master Swordsman. He gets a chance to repair his reputation by instructing the team E601, which seems to be facing some difficulties. It consists of three girls, Misora Whitale, Lecty Eisenach, and Rico Flamel, each with problems of their own. It appears that Kanata will get in deep waters more than once because of them...

A bus full of eccentric individuals is headed towards the urban legend known as Nanaki Village, a place where one can supposedly start over and live a perfect life. While many have different ideas of why the village cannot be found on any map, or why even the police cannot pinpoint its location, they each look forward to their new lives and just what awaits them once they reach their destination. After a few mishaps, they successfully arrive at Nanaki Village only to find it completely abandoned. Judging from the state of disrepair, it has been vacant for at least a year. However, secrets are soon revealed as some of the group begin to go missing while exploring the village and amidst the confusion, they find bloody claw marks in a forest. As mistrust and in-fighting break out, will they ever be able to figure out the truth behind this lost village?
