Shion's older brother. He is always clam and composed, never showing his feelings to others. Jun runs an antique bookstore on the outskirts of Second Miltia's capital. He formerly served as a captain in the Galaxy Federation's Special Forces Intelligence Division, but left the military fourteen years ago during Miltian Conflict.
After a brief appearance in Episode I, Jin will be reunited with Shion on Second Miltia.
