From Takashi's flashback in Volume 4, they have known each other since at least middle school. Despite knowing Takashi's feelings, he dated Rei, ultimately betraying him, which led to their estrangement. In Episode 1, after being bitten by Wakisaka, who had turned into "one of them," he vomits blood and becomes the first proven case of "being doomed just by being bitten." He agonizes, lamenting that he doesn't want to become "one of them," and just as Takashi, understanding his former friend's feelings, is about to finish him off, Rei stops him. He then turns into "one of them" and is put down by Takashi. Regarding the living dead, he created the term "them" because "it's not a movie or game, so we can't call them 'zombies'." According to Saya's later interpretation, this was because he realized the possibility that they would have to continue fighting "those who should be human."
