Sekifumi Iwata

This doctor is known for his morally reprehensible and lecherous demeanor, his standing in the medical field largely stemming from family connections rather than true skill. A prominent feature of his appearance is a distinctive X-shaped scar covering his face, a mark inflicted by his cousin, Norikuni Iwata, which fuels a deep-seated animosity. His character draws inspiration from Osamu Tezuka's Black Jack, though his appearances in the anime are limited compared to his presence in the manga.
