Born to Hajime and Aki Terakawa, Tomo lost her mother at age of four. Growing up, the girl became devout in her Buddhist upbringing and contemplated taking a religious path in her career when a dream caused her to awake as Sailor Enceladus. Moving from her home city of Kyoto to Tokyo to be closer to Hotaru, Tomo now dedicates herself to guarding the senshi of Saturn, as well as providing a spiritual guide to all Saturn Satellite Senshi.
