She is more commonly known as Lena by her friends and as Handler One to her subordinates, and is an elite Republican soldier who rose to the rank of Major at the young age of 16. She is the commander of Shin and the Spearhead Squadron, whom she communicates with via the long-distance communication device known as the Para-RAID.
After commanding Spearhead, she becomes known for demanding orders and highly competent leadership, earning the nickname Bloody Regina among the Processors.
Despite Lena's humble opinion regarding her own abilities, she is undeniably one of the best officers the Republic has to offer. Her talents, combined with her determination, allowed Lena to be promoted to the rank of Major at the age of 16. Unlike her fellow handlers, Lena took her role seriously and was determined to do everything she could to help her Processors during combat. During her tenure as the Handler of the Spearhead Squadron, her effective support helped the Squadron to a degree that for a brief time it suffered zero casualties. As time passed, she became even bolder and willing to use questionable methods such as guilt-tripping, bribery, and physical threats to achieve an objective. During the special reconnaissance mission and after, Lena often deployed the interception cannons as artillery support without authorization, which incurred the ire of her commanding officer.
