Physical Description

As a human, Leone is the tallest character in the cast.[3] His skin is more suntanned compared to other characters (as of recent art; he was pale in early drawings), and has a stern, sharp face, with some visible wrinkles, as well as a goatee. His eyes are red. His hair is blonde, gelled, and slicked back. He wears a rather loose and revealing undershirt, held at his waist by a thick brown belt. A gold dog tag necklace hangs around his neck, as well as a white beach towel. A big red coat hangs over his shoulders. He sports a pair of grey, striped trousers, and brown derbys.

As a bird, he is a lutino cockatiel, usually drawn smoking a cigar, and bearing a stern facial expression.

Personality and Traits

Leone is described by Hiyoko as being a "quiet, foppish bird". He appears wary and appropriately suspicious of things around him, given his occupation. As an S-Class Agent, he has plenty knowledge about bombs and how to disarm them, and provides aid to the characters for the sake of justice. He also has some knowledge about medicine, as essentially it is him who saved the day in Holiday Star, and Yuuya's life in BBL.

He doesn't let things get to him easily, but apparently is somewhat known for looking unapproachable, and students aren't the most fond of him.


Yuuya Sakazaki

Leone JB trained Yuuya as a Dove Party agent. When Yuuya received his mission to gather information on Hawk Party researcher Souma Isa, Leone was assigned as his agent handler.

Yuuya and Leone appear to have a trusting relationship, which is demonstrated on multiple occasions. During "The Day the Night Slept (After)", Leone trusted Yuuya enough to allow him to risk his life for his brother and classmates, while Yuuya trusted Leone enough to allow him to inject him with psychotropics that would be lethal in the event of an overdose. When Ryouta and Sakuya go to the maintenance office during the Bad Boys Loveroute, Leone only takes Ryouta and Sakuya seriously when they tell him that Yuuya sent them. He even offers his office if Ryouta and Sakuya need to take a break and rest, stating that "[a]nyone Mr. Sakazaki sends is trustworthy".

Leone seems to genuinely care about Yuuya, even going back to recover Yuuya at the risk of his own life at the end of the Bad Boys Love route. Yuuya also seems to look up to Leone; and during "The Day the Night Slept (After)", Yuuya finds the sight of his handler very reassuring.
