Shindo, Ranmaru

申道蘭丸

Alongside his young sister Saya, he is one of the original survivors of the Machida massacre. He joined the police force to determine who was responsible for murdering his parents. Assigned as a non-uniformed detective in the Tokki division at the Shibuya Precinct, he discovers through his work that demons from the dark realm orchestrated various massacres to destroy Japan. Subsequently, he joins the Tokko division to save the country from being overrun by these demons. He suffers from post-traumatic stress disorder resulting from the massacre and the deaths of his parents, which occurred when he and his sister were still in college and high school, respectively. He originally had brown hair but dyed it yellow with orange highlights after graduating from high school. His symbiont tattoo is located on his right arm, and a second one appeared on his left shoulder following his 'awakening'.
Because he survived the Machida incident, all Phantom demons received orders to eliminate him, as well as any other witnesses who had seen the events.
As the only survivors of the Shindo family, he and Saya grew very close after being tragically orphaned. It can be inferred that he harbors feelings for Sakura Rokujo during the series, particularly in scenes where they are alone on a building's roof discussing how glad they were to meet.
