With great advancements in technology, mankind has created hIEs,
human-like robots that act as public and personal servants for society.
Unlike many others, the kind-hearted high school student Arato Endou
treats hIEs as equals, but his financial situation keeps him from ever
owning one.
However, his normal life is shattered when an ordinary run to the local
grocery store goes horribly awry. Viciously assaulted by a hacked hIE,
Arato is on the verge of death; but luckily, he is saved by an abnormal
hIE carrying a weaponized coffin. Her name is Lacia, one of five highly
advanced hIEs that recently escaped the clutches of the mysterious
MemeFrame Corporation.
Faced with a hacked car threatening to run them over, Lacia offers Arato
a deal: in exchange for saving his life, he must register as her new
owner, thus taking full responsibility for her actions. With little
choice, he decides to trust this artificial girl and allows her to live
in his home. Though Lacia begins to adapt to her new, peaceful
lifestyle, she warns the entranced Arato of one thing—she does not have a
soul.
