Hiwatari Satoshi♂

Satoshi Hiwatari is the police commander in charge of capturing Dark. He is extremely intelligent, Satoshi graduated from high school at the age of eight, and obtained a college degree at the age of 13. He enrolled in Daisuke's middle in order to be closer to Daisuke, whom he knew was Dark's alter ego. Calm and composed, he often pays little mind to those around him and rarely shows his emotions causing others to find him distant and cold. Daisuke seems unaffected by his distant nature, and insists on becoming his friend. Reluctant at first, Satoshi comes to accept Daisuke's friendship, though later withdraws from school to try to distance himself from Daisuke again out of fear. He eventually returns to offer to aid rescuing Risa from Argentine. Satoshi is the last heir of the Hikari family, which created powerful artworks that the Niwa family has been stealing for years via Dark. In the anime version, Kosuke made a play on words with Satoshi's last name being synonymous with light (also pronounced 'hikari'), though the kanji for Satoshi's family name actually means 'ice hunter'.
