Princess x Princess

Fall has arrived at Verbena Academy and Princess Lithia of the divine realm couldn't be more content. Her childhood crush Raito became her boyfriend this summer, and she is experiencing earthly autumn for the first time. As their relationship develops toward marriage, she begins to think about the future in terms her human surroundings do not quite account for: where she comes from, polygamy is normal and accepted. Her conclusion: the relationship would be perfect with a second bride. Without telling Raito, she begins a secret search for a candidate. Then a mysterious aircraft lands on the school grounds, and the amnesiac girl who steps off it introduces a complication that changes everything about what Lithia thought she was planning.
