“I Am a Hero is probably the greatest zombie manga ever. It has the slow buildup of a psychological horror manga, but when the zombies hit, they hit hard, and the manga accelerates into volumes-long fight-or-flight sequences that seem like they’ll never stop.” -Jason Thompson (Manga: The Complete Guide)
