The girl and the beast should never have met, but when they do, a quiet fairytale begins. This is a story of two people--one human, one inhuman--who linger in the hazy twilight that separates night from day.

    He's pretty bad at cooking and doesn't have a huge appetite to begin with, but chance brings his little family and one of his students, Kotori Iida, together for homemade adventures. With those three cooks in the kitchen, it's no wonder this dinner table drama is so delicious.

    In its chambers a small community clings to survival, most dying young from the very powers that sustain them. Chakuro is the Archivist for the Mud Whale, diligently chronicling the lives and deaths of his people. As one of the saimia wielders, whose life spans are cut short by their own magic, he knows his time is limited and is determined to leave a better record than his predecessors. But the steady pace of their isolated existence on the Mud Whale is abruptly shattered when a scouting party discovers a mysterious young girl who seems to know more about their home than they do…

    Fortunately, she's not alone... she's got a whole human body's worth of cells ready to help out! The mysterious white blood cell, the buff and brash killer T cell, the nerdy neuron, even the cute little platelets -- everyone's got to come together if they want to keep you healthy!
