Upsilon

Upsilon or Upsilon Masst is the Deuteragonist of SPECIMEN 4V17, and is the best friend of the main character Vier. She is a Violet Sacre User and a member of the sacred and ancient Masst Clan. In the beginning of the story she enters the PSTF as a secret agent from ROGUE, she was given a task by her father, Lauen Masst, the founder and the current leader of ROGUE at that time, to gather information of what the facility is experimenting on and retrieve the General's Daughter. Upsilon was a mere Regular Scorer among the others and didn't stand out from the rest, she was introverted and had Vier as her only best friend and was also quite close with Acht a roommate of hers. Upsilon helped her friends escape PSTF with the help of the twins, Hans and Eileen Jannsen, Upsilon's allies from ROGUE who have already escaped and graduated from the PSTF in the past, they escorted Upsilon and her friends to an inn they secured nearby, however she didn't manage to find out any information about the General's Daughter. Upsilon was then grouped into the Runaway PSTF Specimens by the Prais government. When they returned home to Rotamm, Upsilon and Hans tried contacting ROGUE, however they were inactive and were deemed to disappear. Upsilon and her friends finally arrived at Rotamm's capital Kapitel and were quarantined by the RGO (Rotamm Government Official) for absurd reasons, they were deemed to be 'non-existent'. Because of Vier's proposal, all of them joined the Battle of Firans District to be able to change their statuses and live in Kapitel. Upsilon joined Team Attack, Sieben awakened as a traitor among the team and managed to murder the entire group except for Vier and Upsilon. Upsilon was saved due to her Sacre activating in a life or death situation, her body used the Sacre ability Protection which saved her life, however this caused herself to be in a coma for a few months. After waking up, she was intrigued by Vier's secretive behavior. She soon learned from Vier what saved her during the Battle of Firans District. She was introduced to Eir Egildottir by Vier, however she already knew her from a past encounter. She was offered to join MAG✛A by Eir, she refused and tried to convince Vier to leave. Vier didn't want to leave nor did want her or Erin to be involved with MAG✛A and decided to cut ties with them. They were both deeply disappointed of what just happened. Later on, MAG✛A caused a Palace Crisis, which was led by Vier, Upsilon went on with Erie to stop her. During the events of the Palace Crisis, Upsilon discovered that Erin might be the solution. She also discovered that MAG✛A was initially ROGUE and was made by her father, which caused her to whole-heartedly despise the organization due to her hate for her father. Upsilon made an oath to herself to bring back Vier, stop MAG✛A from causing anymore destruction and try to find an end to this war.
