I Am 100% Human But Not Edible For Zombies! (」ﾟﾛﾟ)｣

At the start of apocalypse, humans transform into zombies or the human-eating undead monsters. I heard their cries of suffering and fear. Also, the world set new rule called "survival of the fittest". Fortunately, Gods pity on them and give them superpowers to fight back but why is it that zombies are ignoring me?! (」ﾟﾛﾟ)｣



And, wait! Why are these zombies vomit when they bite me?! Am I not edible?!!(◎_◎;)
