Sylvia Mercury First (シルヴィア・マーキュリー・ファースト) is a highly regarded female CO who attained the title of "First" at an early age. She is introduced as the roommate and support personnel of Angelina Kudou Shields during her missions in Japan.

Besides from her first name Silvia, the rest were all code names, meaning that she ranked first among the Stars planet-class "Mercury".

Given the requirements of the infiltration mission, it was vital for Angelina to hide identity and avoid terms like "High Commander" or "Major", hence why Sylvia is ordered to use her pet name Lina. As Silvia originally possessed an unrestrained personality, she quickly forget about the differences in military rank and warms up to Lina.
