Does history repeat itself? Or does it not? St. Kleio Academy is an extremely exclusive school where every student is a clone of a renowned historical figure, including Beethoven, Queen Elizabeth I, Napoleon, Mozart, and Freud. Everyone, that is, except for Shiro Kamiya. While Shiro struggles to adjust to this peculiar campus, the academy's first graduate—a clone of John F. Kennedy—is murdered. Are the clones destined to suffer the same fate as their genetic originals, or can they forge their own paths? And where does an ordinary boy like Shiro belong?
