Altar of Invocation

"Do you think we are the same as human?"
*
To overcome the decline in human resources due to the infertility epidemic, SEES tried to create artificial humans who could think and feel like humans. Until nineteen years later, Professor Lant succeeded in creating a perfect AI named Ivy.

With Ivy's success, Professor Lant tried to develop the perfect AI by creating Augfheim - an artificial world where AIs grow. Ivy was assigned to help them, and met Ash and Ciel in Junon City.

However, Professor Lant's childhood friend and leader of the military organization ISAC, tried to destroy IVY and develop a killer AI. Lavent captured Professor Lant, then hacked into the world of Augfheim and took IVY into custody.

Because of their friendship, Ash and Ciel plan to rescue IVY. However, during their journey, the great secrets of their world begin to be revealed.
