Millrew, often nicknamed Mills, is a 13 y/o letter-symbol hybrid boy. he has only one eye, just like his mom Nabla, but other than that he's just an average kid. hes snarky, sarcastic, quiet, introverted, and even very rude at times, but can be caring when he needs to. hes an only child from his letter father M, and his symbol mother Nabla. despite looking quite normal, he has above average strength and speed. he doesnt understand his parents, and thinks theyre kinda gross.
