Sho Kahara (華原 ショウ Kahara Shō?), also known as the Black Knight, Knight (黒騎士・ナイト Kurokishi Naito?) and the Hacker Tamer (ハッカーテイマー Hakkā Teimā?), is Tsurugi's childhood friend, though he has grown distant with time. He is protective of his black Digimon Mini, even shoving Tsurugi away when he moved to take a closer look. As Knight, he has the power to turn the Digimon he defeats into trash data, unable to be reborn.
