My Family Really Does Have a Throne to Inherit

[Added June 17, 2021: Hiromu Arakawa is an idiot! If you're going to read Fullmetal Alchemist, don't spend money on it. She doesn't deserve it!] I'm the eleventh princess of Xing. Though I'm a princess, my life isn't all that comfortable. I have 24 brothers and 18 sisters, and aside from one younger brother, we're all half-siblings. We fight to the death for our father's throne because otherwise our mother's clans won't survive. To help my younger brother claim the throne, I set out with him and our Yao clan retainers to Amestris in search of the legendary Philosopher's Stone... Then, for some reason, after losing consciousness in battle, I ended up in a place called Japan. Everything I've said is true. It was only after I got to know this world's culture that I learned my situation was probably called transmigration. “So, what's the point of all that?” “I want our first child to take my family name, because my family really does have a throne to inherit.” Then I saw my boyfriend give me a subtle look of pity reserved for the intellectually challenged.
