Giovanni

, better known as, is the Battalion Commander of the 3rd Special Fire Brigade.

Appearance
Giovanni bears a resembling appearance to a plague doctor, as he wears a stitched white mask with a large beak over his entire face, with lenses for vision. Atop his head is a black top-hat, and he wears a white scarf around his neck, disclosing any skin on his upper body. He wears a dark v-neck jacket, dark trousers, dark shoes, and carries a white cane with him.

Personality
As a doctor, Giovanni is exceptionally intelligent and likes to experiment on things. He can be quite pushy when it comes to getting what he wants, and isn't afraid to say what everybody else is thinking.

Tracking the Preacher arc
Dr. Giovanni introduced himself at the conference of the Battalion Commanders in Central Tokyo. After the reveal of Shinra obtaining the Adora Burst, Giovanni suggests that he be put under extra protection from the Preacher, seeing as Shinra is his target, and hinting at Giovanni's temptation to experiment on him. This is ultimately turned down by the boy and Hibana. After the conference, Giovanni confronts Hibana alone, commenting on her affiliation with Haijima like he is, though it seemed like she's treating the 8th Brigade special. She calls his statement nonsense and leaves by saying she'll send data on the giant Flame Humans, much to his irritation.

Trivia

 * His appearance and occupation heavily imply that Dr. Giovanni was based off of a plague doctor — a medical physician, who used to treat people that were infected by the plague and used various perfumes held in bird-like masks to drown out the scent of the deceased.
