Mrs Zeppeli

The wife of Gregorio and the mother of five children, she cooks the meals for her family and cares a lot for them, as shown when she kisses Gyro's cheek before he became his father's assistant as an executioner. She doesn't have much medical expertise nor the ability to use Steel Balls, but she assists Gregorio and Gyro as a nurse.
