Hiwatari, Satoshi

日渡怜

Satoshi Hiwatari is consistently calm and composed, rarely displaying emotion. He presents as a distant, cold, and silent figure, yet this demeanor does not seem to hinder his closeness to Daisuke Niwa. He is highly intelligent and holds a college degree. Nevertheless, he attends Daisuke's junior high school in an effort to lead a normal life. He serves as the police commander responsible for capturing Dark.
Driven by his family legacy, he is nearly obsessive in his pursuit of Dark. As the sole surviving member of the Hikari family, whose artworks are almost invariably targeted by Dark for theft, Satoshi is deeply invested. During the Toki no Byuushin incident, he recreates one of Daisuke's paintings, asserting that he can mimic any artwork after seeing it just once. His reproduction is a precise imitation, indistinguishable from the original.
He was adopted by a 26-year-old police officer named Hiwatari, leading to a change in his surname to reflect the adoption. Throughout the story, he gradually begins to care more about Daisuke's safety. It appears that Daisuke acts as the trigger for Satoshi's alternate personality, Krad, to emerge. Satoshi strongly opposes Krad taking control of his body; he has adopted an uncaring persona to "seal his heart," and thereby, Krad. Krad is Dark's "evil twin" or opposite—a homicidal blond whose sole motivation seems to be eliminating Dark.
