When he was alive, Zato was known for having a calm disposition and was someone who would analyze each aspect of a problem with great consideration.

However, that changed when he died. Being subjected to the entirety of human experiences endlessly in the underworld has burned out all emotional capacity within him after being resurrected. As such, he perceives no value in anything, including himself. Good and bad, joy and anger—these are all just words to him. He claims the world is a dull place, but even that is a statement born from his stoic analysis rather than his feeling.

Still, there is one exception to his ennui: Millia. Only around her can he feel anything close to what one might call emotion.

Zato is the former head of the Assassin's Guild and can manipulate his own shadow. He was once at the very bottom of the Guild hierarchy, but after trading his eyesight for the curse to control shadows provided by the Post-War Administration Bureau, he quickly rose through the Guild's ranks.

Soon after becoming the Guild leader, he launched a large-scale mission that deployed many of the Guild's personnel, ultimately failing due to Millia Rage's betrayal, who held a crucial role in the mission. The Guild suffered a great many losses, including the capture of Zato himself by the authorities. The affection he had for Millia turned to hate, and the thought of revenge engulfed his mind during his time in the dimension prison.

Not long after his incarceration, he learned of the Second Holy Order Selection Tournament, which allows the participation of criminals. Believing that this was his chance to exact revenge against Millia, he participated in the tournament.
However, his mind and body were weakened gradually due to the price of his curse, and his body was eventually taken over by the shadow (Eddie).

Eddie's ascendancy did not last long as Zato's body continued to deteriorate. As the body withered and came to an end, Eddie died along with it before he could find a new host.

Eventually, Zato was resurrected at the hands of the Conclave. However, perhaps due to his time in the Underworld, he became indifferent towards all matters—save for one exception, Millia.
After reuniting with Millia and reaffirming his feelings towards her, he swears to protect her at all costs.

He is currently a member of the reconstituted Post-War Administration Bureau, where he works together with Millia to support Illyria from the shadows.
