I reincarnated as the great ancestor of an empire.

Reincarnating, normal. Being a woman, well, sometimes it comes in the combo package. Having a territory at the principality level, that's where we start having little problems. But being the great ancestor of an empire and apparently having lived thousands upon thousands of years... that's when you can go into total panic mode, activate all the alarms, and seriously consider screaming into a paper bag. Apparently I reincarnated into the world of a visual novel game and apparently I reincarnated into the empire that appeared on very rare occasions.
