: A Master and High Driver of the Dryfe Imperium. He specializes in piloting giant robots called Magingear, which he can power up using his Embryo Cocytus. In real life, Hugo is actually a girl called Yuri Gautier and she created the Hugo character in an attempt to emulate the knights in shining armor from theater plays she enjoyed. He is member of the Triangle of Wisdom and goes along with Franklin's plan to invade Gideon, thinking it will keep casualties to a minimum and bring the Altar-Dryfe war to a quicker end. As the invasion starts, however, Rook makes him realize Franklin never had any intention of sparing the citizen and he actually wants to destroy the city and kill as many as possible, causing Hugo to betray him and instead assist the city's defenders. As Ray confronts Franklin, however, Hugo steps in to defend him, revealing that Franklin is actually his older sister, Francesa. With Franklin losing the battle of Gideon, he removes Hugo from the Triangle of Wisdom in an attempt to protect him.

In the real world, she used to be a manga artist who created "Marie Adler" as the main character of her manga until she hit writer's block and used ''Infinite Dendrogram'' as a way to live vicariously as Marie.

His Embryo is Pandemonium, a large monster holding a monster-producing factory on its back. He initially uses a penguin suit and the "Dr. Flamingo" alias to travel across Altar without arousing suspicion, but he later reveals his true identity everyone in Gideon as he begins his plan to end the war between Altar and Dryfe. He gains an interest in Ray after watching him subvert his plans to weaken Altar, to the point he tricks Ray into drinking a potion that informs Franklin of his status and weapons and later uses that information to create a monster with the express purpose of killing Ray. As the battle of Gideon ends, Ray defeats Franklin, but not before Hugo reveals that Franklin is actually his older sister Francesa. With his forces depleted, Franklin removes Hugo from the Triangle of Wisdom, both in an attempt to protect him and to undo any moral restrains he himself may have in his goal towards beating Ray.
