Hisashi Igou is Rei's classmate and boyfriend. He, Takashi, and Rei were among the first to try and escape the rampage at the school. On their way out of class, he was bitten by an infected teacher and subsequently turned into one of "them" afterwards. Aware of his fate, he instructed Takashi to kill him before he turned by throwing him off the rooftop of the school building, but died before Takashi could do so, and rose back up as one of "them". Takashi then gathers himself together and takes down Hisashi permanently. A brief bitterness between Rei and Takashi occurred as a result from his death. He was thought to be one of the main characters of the manga because during the first chapter, he was portayed as the cool, calm-headed, leader type of character. Hisashi was responsible for "naming" the zombies as "them".
