Zoe Iris A girl with pale pink bobbed hair and light blue eyes, wearing a hood and a mask. She is kind and calm with impeccable medical skills, but she is also an extreme sadist and a kiss-maniac. She claims that by kissing, she can understand her partner through the components in their saliva. She loves insects and travels the world to collect medicinal herbs, catching bugs to bring back as well; the organization members constantly scream at her to stop. However, she shows no signs of stopping or reflecting on her actions. Because she travels the world, she has a globally known alias: "The Black Apothecary." Despite her foreign-sounding name and global travels, she speaks in a mysterious regional drawl within the organization (First person: I [feminine/regional]). While she is a kiss-maniac, she is uncomfortable around men; she never removes her mask or kisses in front of them. In fact, men feel a certain distance from her. She can create anything, including panaceas. She has a high resistance to medicines and poisons (due to frequently experimenting on herself). She is also an expert on toxins.
