Kayla was once an ordinary teenage girl, except she was terrified of aging and dying. On her 18th birthday, she volunteered for the Transcendence Project, a scientific research project to turn robots into humans as a means of immortality. Sixty years have passed, and since then she has remained the same outgoing, bubbly, flirtatious girl she was before. Being immortal and needless, she devotes her time to meeting new friends and pursuing a wide variety of hobbies.
