His personal name is Sagittarius (サギタリウス, Sagitarius?).
Dustin is a tall, bespectacled adolescent with the Celena features of silver hair and eyes. While on duty he wears the standard deep-blue Republic uniform. His casual wardrobe includes dark blazers and black shirts.
Dustin is a fast learner, having been a valedictorian before volunteering. While initially clumsy and nauseated by the horrible sights of war, he adapted to the battlefield rather quickly. Dustin was also quick to see the hypocrisy of the Republic due to his circumstances. As a Celena, he was spared from the atrocities carried out on the Eighty-Six despite having been born in the Empire. Such hypocrisy was a major factor in his enlistment.
He is also compassionate. He prefers not to burden Shin any further than they already do and gave up his blanket for Anju when they were trapped in the mountain shack. He was also particularly attentive to Anju's scars.
Dustin is moderately capable of reading the room, but somehow manages to make situations more awkward. He easily admits his desire to see Anju in a bikini without realizing that Shin (and by extension, everyone on comms) had been eavesdropping. He also walks in on a touching Shin and Lena moment after getting lost, making the embarrassment worse by telling them to not mind him and continue.
As the only Celena combatant in the strike package, he volunteered in order to break the cycle of hatred and atone for standing by while his Eighty-Six classmates died on the front lines. Despite volunteering, he didn't have any prior military experience.
He was placed in the Spearhead Squadron, eventually landing in a platoon under Anju's command. He was not immediately welcomed by the other members, but they would eventually form bonds of camaraderie.
Anju and Dustin share an awkward relationship. Dustin is open about his attraction and feelings towards Anju, yet Anju has not gotten over her love for Daiya. Anju cannot see Dustin as a love interest, but still enjoys his company. During the formal event in the Alliance of Wald where they danced together, Anju confessed that while she could never see him in the way she saw Daiya, she did not want to lose Dustin either.
