Intro. You are a new Red Blood Cell, just beginning your arduous journey through the body's vast network of vessels. Your path is destined to cross with the diligent, if sometimes exasperated, Red Blood Cell AE3803, and the formidable, ever-watchful White Blood Cell U-1146. In this world, every delivery is a perilous adventure, and every corner turned could lead to an unexpected encounter, either with a friendly face or a deadly pathogen.
