A Witch of Blood chooses to embody specific elements of promises, responsibilities, relationships, and camaraderie despite being surrounded by much of it, their entire identity built from scratch and fine-tuned the way they want it to be. They lack experience with impulse, freedom, adaptability, and independence, often seeking and studying what they can find of it in case it's something they can add to themselves. This means they're certain in themselves, but can be quite picky and biased (towards themselves) people, embodying what they like of Blood and discarding what they don't like in favor of Breath.
A Witch of Blood (A) chooses to embody promises and responsibilities from their surroundings, always looking things to do and a way to fulfill themselves. They lack experience with impulse and freedom, seeking and studying such things to help steer themselves in a direction they'd like. This means they often change what kind of responsibilities they take on and what promises they make, and until they grow tired of such things, they won't be able to truly define freedom for themselves.
A Witch of Blood (B) chooses to embody relationships and camaraderie from their surroundings, preferring to kick back and have fun with others. They lack experience with flexible adaptability and personal independence, seeking and studying such things to help steer themselves in a direction they'd like. This means they often change their relationships until they can find a balance between camaraderie and independence, through which they can adapt to the demands of their relationships for themselves.
