Storyline

The player assumes the role of a young treasure hunter who has learned of the existence of an ancient, treasure-filled ruin underneath Kamiyoshi Academy in Shinjuku, Tokyo. Entering the school as a faux transfer student, his true goal is to explore these ruins and unearth the treasures (and OOPArts) they hold. This is not an uncomplicated task, however: the ruins reveal themselves to be an upside-down Ancient Egyptian pyramid, guarded by traps and age-old monsters of Japanese myth – and the school's student council, being more than it seems at first glance, is equally determined to get in the way. The story is told as in an anime: divided up into "episodes", each one starts and ends with the same opening and ending sequences, and has separate sub-stories contained to each episode.
