Kagehime no Konrei  

The Wedding of the Shadow Princess, Two Princesses, Two Princes, 影姫の婚礼

Izuna has been living as Princess Kisara of the East country for some time now, dedicating herself entirely to represent the weak health princess. Although only a few people at the Royal Palace knew about Izunas true identity, she was called by her real name only by the actual princess. Her service as Princess Kisaras double was supposed to end once it was decided that the princess would marry the Crown Prince of the West country to establish peace between the two nations. However, just a few weeks before the wedding ceremony, Princess Kisara's health deteriorated suddenly. The princess realized she had failed to free Izuna from serving as her double and apologized repeatedly at her deathbed, leaving peace on Izunas hand. Now, Izuna will likely have to continue living her life as Princess Kisara, marrying someone from the enemy country. She has vowed to fulfill the dying wish of the princess but promised never to fall in love with her future husband. So, what exactly awaits Izuna in the West country?
