Based on a game by Alice Soft. Two large countries, Leben and Carnea, had been ruled by kings of character, and their people had lived in peace. However, Leben suddenly invaded Carnea, and the two nations went to war. The fighting remained evenly matched for over six months, but after the king of Carnea died of illness, Leben gradually gained the upper hand. Recently, a man in a black suit visited Carnea. He was Claude, the former vice leader of the Carnea Knights, who had vanished eight years prior. His appearance had changed completely, arousing suspicion. Yet, when he proposed a plan to defeat Leben, they listened. He suggested hiring experienced mercenary soldiers and having the queen and princesses sell their bodies to raise funds. The queen and her daughter accepted his plan and began taking his "lessons".
