Aria, a former high school student, underwent reincarnation as an aristocrat's daughter, and was betrothed to meet with Prince Eugene, a reputedly strange and eccentric individual. In their conversation, he revealed to her that he was Oda Nobunaga in a previous life, which Aria thought might have been the reason behind his previous engagements falling through.

Thus began Aria's days of being pursued by one of the most formidable and influential princes in the world, with the capability of uniting entire nations.
