Fujisawa Kazuo is best known as the first real antagonist players face in the Liar Game Tournament—and notably, he's the one who takes on Kanzaki Nao in round one, despite having been her middle school teacher. That relationship adds an extra layer of betrayal to their matchup.
On screen, he's played by Kitamura Soichiro in the Japanese drama adaptation, while the Korean version recast him as Hyun Jung-bum.
Visually, Fujisawa comes across as a weathered middle-aged guy—graying hair, lined face, teeth that could use some work. He typically dresses casually in slacks and a collared shirt, nothing fancy.
The thing about him is the stark gap between his public persona and who he actually is. He acts kind and caring, especially around students, but his true nature emerges the moment he starts lying. Fans often speculate that his past losses—he lost a wife and child at some point—might explain the bitterness underneath, but honestly, he just cares way more about money than he does about people. Not even his students or supposed friends matter if there's profit on the table.
