This anime game revolves around a high school student named Takumi Nishijo, who is embroiled in a bloody crime scene on the way home, since then more mysterious events begin to occur, as other equally bloody murder. Takumi has started to face reality and "delusions" that experience to avoid being trapped by the author of these crimes.
As for the story, the show starts out as a mystery-thriller, but a few episodes in, it decides to be a shounen action series with Takumi having a personal army of chicks with magical swords who fights an evil man who claims his actions are for the greater good of humanity. While ambitious story-lines are commendable, the show should have stuck to its murder-mystery roots instead of expanding to a convoluted doomsday scenario driven by “scientific” babble.
