Hana Tsu-Vachel is the main protagonist of the Fear Effect series. Orphaned as a child due to the death of her parents, she was taken in by the Chinese Triad and forced into a lifelong contract with the organization. She routinely accepts dangerous missions in the hopes that she can one day buy off her Triad contract and be free from their control.
- "Part French, part Chinese, and fluent in six different languages, most of Hana's background is shrouded in secrecy. Rumor has it that she was raised and trained by the Triad in its "Black Inns" of Shan Xi. While a world-class marksman and ace pilot, Hana's true speciality lies in the dealings of love and death. Her orphan upbringing conditioned her to be distant to those that she does not know and to be careful whom she trusts. Desired by many yet belonging only to one, Hana lives life with passion and without reservation. Occasionally taking on assignments from the mysterious Jin for the extra cash, Hana's primary goal in life is to buy back her "contract" from the Triad so that she may leave her past behind and control her own destiny."
