Giovanni

, better known as, is a Second Generation, and the Captain of Special Fire Force Company 3. Later on, he is revealed to be working under the Ash Flame Chivalric Order.

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. Later is seen wearing a skinnier variant of the Special Fire Force jacket, with a dark scarf around his neck.

Later on in the series, when Giovanni's true intentions are revealed, he changes his clothing into a large white cloak that covers his entire body from the neck down; maintaining the plague mask and top hat. He's shown to have long, skinny arms and fingers, and hides an unknown (though huge) amount of mechanics underneath this white cape.

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. Giovanni is very suspicious, secretive and deceptive. He is willing to go as far as killing somebody simply because they won't join forces with him.

Preacher Pursuit arc
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 Infernals, much to his irritation.

Post-Asakusa arc
Giovanni appears to Vulcan at his his workshop, persuading him to work with Haijima Industries, but Vulcan denies his request, stating that Giovanni is the man who killed his family years ago. Giovanni leaves him, and meets with members of Company 3, telling them to attack and kill Vulcan, while at the same time revealing themselves to be members of the Ash Flame Chivalric Order.

Soon after, Giovanni begins his personal attack on Shinra. Using his Second Generation ability, he effortlessly terrorizes Shinra from a distance, while he attempts to out-chase Giovanni's wired hand. Giovanni finally confronts Shinra close-up, electrocuting him to the point of unconsciousness, saying he'll bring the boy back to the Preacher to use his Adora Burst

Trivia

 * His appearance and occupation heavily imply that 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.
