After the Crown Was Taken [Interstellar]

The queen who conquered new lands and built an empire dies peacefully of old age. But when she opens her eyes again, she's in the interstellar era, the last surviving heir to the empire, stranded on a barren planet after a bloody coup. And when Feng Li arrives, the imperial jewel has just taken her own life. She removes the only gemstone around her neck, ties it to a bloodstained handkerchief, and climbs aboard a discarded mecha in a junkyard to carve the royal crest herself. From that moment on, arrogant sneers and gossip can no longer hurt her. Later... The most powerful noble, who broke his marriage vows, kneels in the middle of the street and refuses to get up. A former relative who betrayed her in secret stakes their life to offer her their loyalty. The head of an enemy nation, who has been eyeing her covetously, lowers his head and kisses her fingertips, saying only, “Would you accept me and everything I have?” Feng Li gazes into the distant stars and curls her lip in scorn. “On the day the Rose Mecha reappears in imperial airspace, I will crown myself.” - Theme: Never say women are not heroes; their swords sing against the wall night after night.
