Clara, also known as Psiren, is a cat burglar who advertises her crimes to keep Aquroya, a city that resembles Venice and is on the brink of disappearing beneath a lake, lively. She employs alchemy using cards and water in her chest-mounted transmutation circle, which she uses against men by unzipping her shirt and utilizing her powers. Ed's first female opponent, Psiren/Clara, was known for her beauty. During their encounter on a roof, Ed accidentally grabbed her left breast with his automail hand while tackling her. Psiren/Clara also exploited Al's gullibility by posing as a nurse, nun, and schoolteacher while stealing to save hospitals, convents, and schools. She displayed an interest in Edward and even offered to steal anything he desired when they parted ways. After her arrest, Psiren/Clara effortlessly escaped an hour later. Unfortunately, she does not appear in the manga.
