Merim Tser♀

Merim Tser is the younger daughter of the Tser family and the long-lost little sister of Captain Ruberan. Born into a poor household in the economically unstable Helman Empire, her parents were unable to sustain the entire family and Merim was eventually sold as a slave to the Aristocratic Golch Family, being separated from her older sister as a result. As the personal slave of Bitch Golch, Merim experienced a great deal of abuse and mistreatment. She was used to serve him and his family as a maid, a sexual outlet, and experienced heavy torture due to the family's sadism (who often enjoyed whipping her).

Despite all the horrible things she went through with the Golch Family, she was given the opportunity to study and learn a lot about archeology, history, and mechanics. This lead to her becoming a great explorer and archaeologist due to her natural talent and enthusiasm for learning.
