Ultra Otome: Pandora's Box Mission

18-Year-old Isadani Elordi went to Japan as a short-term exchange student. Affected by the light in the auditorium and confused about her own life experience, she chose to join the UPG special search team to investigate paranormal phenomena. During an operation to capture cosmonauts, she accidentally lost her relatives and was buried in the sea. She woke up again and found that she was already the Grand Duchess Katya Stuart of the Titan Dynasty of Pandora. When she learned that the truth about the death of her parents was caused by the racial war in the Kingdom of Light, she vowed to take revenge. She stabilized the power with her judgment and leadership. She disguised herself as a man and assumed another identity, Anton August, and as an envoy of the Titan Dynasty, she sneaked into the Kingdom of Light to collect intelligence and fully prepare for the war. After the war, her aunt arranged a marriage to Molde, the great monarch of the ancient Azerbaijani Empire, and she was involved in a series of conspiracies. After her aunt died mysteriously, she became the heir to the throne, but she became a thorn in the side of more people. Under great pressure from the environment, she chose to marry Molde and disappeared, planning a revenge. The grudge against the three ghost brothers and sisters came to an end, and she faced the test of fate again - she was charged with the mission of destroying mankind. After becoming possessed, her lover also faced a choice. He kills his loved ones to save the world? Or choose to destroy together to save your lover? Where will the blue phantom go, which is disconnected from her? Why did the sudden appearance of Tartarus, the Absolute, cause chaos in time and space?
