Czesław Meyer

Czesław Meyer is the youngest Advenna Avis immortal in the series «Baccano!». His guardian, Fermet, tortured him to test the limits of immortality, but Czesław managed to devour Fermet, ending his suffering. Unfortunately, he discovers from Fermet's memories that he was merely a source of amusement for Fermet. This leads Czesław to become paranoid and distrustful, making it his mission to devour other immortals before they can devour him. In the 1930s, he appears indifferent to the lives of others, but after meeting Isaac and Miria and receiving forgiveness from Maiza, he stops hunting other immortals.
