The year is 2222. It has been years since Tears of the New Moon, a mysterious rain, poured and wiped out almost the entire human race. The poisonous rain gave birth to deformed creatures devouring humans, and humanity fled from the danger. As means for survival, the humans then build an underground haven; Amasia. In this newly built dystopian city, in a pursuit of maintaining their existence, they run into an Artificial Intelligence named Magus. Not knowing how things will work between them, the story of how Humans and AI coinciding and trying to find their truths begin.

The second cour of SYNDUALITY Noir.
 
Despite returning victorious from a dangerous struggle, Kanata and his friends have, in a sense, lost a key ally, the amnesiac magus Noir. Having partially recovered her memory, Noir reverted back to her former personality: that of Mystere, who acts in a patronizing manner toward her master Kanata. However, Mystere remembers detecting a signal from Histoire, a mystical city, during her former life as an artificially intelligent magus.
 
Meanwhile, Tokio disappears from Rock Town while hunting down the ghosts of his past; however, shocking revelations await the deeper his search goes. As Kanata, his childhood friend Ellie, and the magus diva Ciel set out for Histoire, a hostile organization named Ideal sends assassins after them. If Kanata wants to stand a chance at accomplishing his dream, he must uncover the unpleasant truth about Ideal—and some of his closest allies.

A short animation of the TV anime "SYNDUALITY Noir" posted on the EMOTION Label Channel. 

I am Ellie, 17 years old. I am a member of "Avanture," a group of drifters who protect Rocktown from the Enders, a threat to mankind. My childhood friend Kanata found a mysterious magus "Noir", and another diva magus "Ciel" has appeared. What should I do? I don't want to get in the way of Kanata and his friends, but look my way once in a while, won't you! It would be easier if I could be honest about my feelings. I'm trying to cook, dress up, lose weight, and my partner Magus Ange comforts me. I won't give up so easily!
