Season 1

Brothers Shin & Jun Kanzato return to their hometown of Ayanagi City to reunite with their older sibling & police chief Ryo. Shin grows suspicious when Ryo, knee-deep in a grisly murder case with impossible victims, tells the two to turn back. This suspicion deepens when Shin develops a mysterious ability called "Persona", and finds himself under assault by those with the same power. Now Shin must uncover what exactly his brother is trying to protect him from. Who is the cause of the murders? And how does it relate to the incident 10 years ago that separated the brothers to begin with? Something sinister is afoot in Ayanagi City, and Shin is going to find out what... before it finds him first.
