Terra Derida was a female Phindian. She was the sister of Guerra and Paxxi Derida and the daughter of Duenna Derida. She was also a member of the Syndicat on Phindar and the assistant of the crime organization's leader, Baftu. Terra had been memory-wiped at age eleven, making her a cruel, angry person and worse than Baftu himself. Duenna watched Terra and took care of her by living in the Syndicat headquarters.
