Synopsis
Hyoudo Riki is a pretty average guy who just happens to enjoy wearing a tiger mask and practicing Kung Fu, which makes him fit right in at Battle Royal High School. Unfortunately for Riki, he turns out to be the doppelganger of Byoudo, the Master of the Dark Realm. When a dimension gate opens between the two worlds, the evil Fairy Master tricks Byoudo into trying to conquer our world—which is much better lit, by the way. Now poor Riki is semi-possessed by his evil counterpart, and the Fairy Master's minions are mutating his classmates into hideous, lustful monsters. To make things worse, all the interdimensional chaos has drawn the attention of a sword-happy exorcist and the heroic Zankan of the Space-Time Police. All of which means Riki is about to face one nasty mid-term exam. The subject is survival, and forget "pass/fail"—this test is graded "live or die!"
