O'Brien, Austin

オースチン・オブライエン

Austin is a third-year transfer student from West Academy who enrolls at Duel Academy. He is a seasoned and efficient mercenary, initially introduced as Professor Viper's right-hand man. However, after Viper's questionable actions lead Austin to betray him, Austin joins Jaden and is subsequently imprisoned by Viper.
Austin uses a retractable Duel Disk that resembles a gun and can be stored in a holster at his waist. In the past, he trained extensively with his father, a mercenary, in jungle terrain to learn survival skills. During his time at West Academy, he applied these skills to performing life-threatening wire stunts to master his drawing technique.
