She returns to the past after being killed during a rebellion against the imperial oppression that took over the blood of the forgotten Empress Arabella, who vomits blood when she moves.

Arabella decided to find the answer from the rebels to extend her life. (-this was briefly translated in a hurry and will be edited after a few hours, maellene ^^)
