When Doctor Frances Ai's younger sister Maura died in a tragic accident six months ago, Frances swore she would bring her back to life. However, the creature that rises from the slab is clearly not Maura. In fact, this girl, who chooses the name 'M,' doesn't remember a single thing about Maura's life. Despite this, Frances expects M to pursue the same path that Maura has been on--applying to college to become a scientist--and continue the plans she and Maura shared.
