An outwardly normal high school student charged with the duty of maintaining balance between heaven and Earth finds his battles aided by a magical sword and a supernatural protector in an animated tale of adventure from director Ryo Yasumura. When Yonosuke Hiruka learns that a horde of malicious demons have escaped the netherworld to plot the destruction of earth with the sister of his faithful sidekick Tsukinojo Inbe, he is forced to do battle with the most powerful forces of darkness. Subsequently stripped of his protective sword by a stealthy demon, Tonosuke is forced to navigate a dangerous world of darkness with no weapon and no means of detecting the creatures that stalk him from the shadows. ~ Jason Buchanan, All Movie Guide
