Tableau Gate

High school student Satsuki Hikawa lives alone in a mansion while his grandfather, his only living relative, travels around the country as an art dealer. When his grandfather sends him an art book called Tablet, Satsuki finds pages resembling tarot cards with most of their symbols missing. A mysterious girl soon arrives, claiming Tablet belongs to her. She warns that the escaped symbols must be found and returned before “they” cause trouble. To capture each one, Satsuki must call out the correct symbol; those he returns to the book become his servants. He sets out to retrieve them all.
