Sanders

Sanders is an instructor at Duel Academy in Fusion Dimension who trained the Battle Beast. He is a serious and strict individual. He firmly believes in Duel Academy's agenda and teaches his alumni with a rigorous mindset. He has shown to be a strategic and methodical individual as he devised a trap to capture the Lancers and often remarking to his students the best course of action in battle depending on the mission at hand. He instructs his students to be completely obedient; anything less will not satisfy him, to the point of threatening the Battle Beast over seeing him smile in relief at avoiding a loss. Sanders seems to be a man obsessed with war and strength as he pursues to create the strongest duel soldiers ever. His enthusiasm is such that he refers to his students as gladiators and as their training grounds as a holy place, seeing no greater honour than in combat itself.

He tends to usher the catchphrase "Glory on the Academia".
