His Personal Name is Baldanders (バルトアンデルス, Barutoanderusu?).
Siri is the captain of the Razor Edge Squadron and operations commander of the Strike Package's 2nd Armored Division. He temporarily became operations commander of the entire Strike Package during the 1st Armored Division's rest period.
Siri has golden hair and eyes. He is described as one of the largest of the Eighty-Six with his toned physique and a height even taller that Raiden.
Siri is a playful young man who dislikes conflict. Due to his large stature, he often received challenges for his position in the Eighty-Sixth Sector. In order to make himself seem unthreatening, he made up a fake story about how he lost his sister in battle and decided to adopt her feminine speech. In a sense, he may be a pathological liar.
Siri was the leader of the Razor Edge Squadron during the fall of the Republic. During that time, his squadron fought together with Rito's Spearhead Squadron in the defense of the Republic and its internment camps. Following the rescue of the Republic by the Federacy, he volunteered for the Eighty-Sixth Strike Package and has since become the leader of the 2nd Armored Division.
