Overview

Sanae Sakuramachi, a CA of Miroir Airlines, was boarding flight 28 from Mexico to Tokyo. Sanae was trying to calm down a passenger, an archaeologist named Ryo Kume, who was having a phobia of flying and was having a panic attack. However, Kume starts a lengthy personal life, and begins to decipher a stone field he says he found in the ruins of the super-ancient civilization Arconia, which opens the door to the other dimensional space Arconia. The plane crash-lands in Arconia. The passengers try to escape from Arconia, but Sanae gets involved with Yodas, a beast that lives in Arconia, and the infected female crewmember turns out to be a leper.
