Princess Knight Lydia

Altein is a fantasy kingdom ruled by two princesses blessed by goddesses: Lydia, a dancer knight, and her younger sister Fregia, a priestess who guards the demonic gates. After their father the king dies, Lydia assumes the throne but is betrayed by her uncle Coretchio, who allies with demons to seize power. The royal guard is annihilated, the castle falls, and Fregia is captured and subjected to cruel subjugation. Lydia escapes to a village below the castle and must find a way to raise funds to hire mercenaries, rescue her sister, and reclaim the throne—all within a time limit. She pursues multiple income sources: trading at the general store, accepting quests through the guild, exploring a dangerous dungeon, and engaging in more morally compromising activities. Her choices determine her fate, with four possible endings ranging from defeat and corruption to triumph.
