The graceful capital city, ancient Kyoto.
A beautiful noble daughter was born between the emperor and his consort, Kiritsubo, who had gained his favour. That beautiful daughter is known as "Hikaru no Miya (The Princess of Light)" due to her unparalleled beauty that is likened to her casting light. The only men that are allowed to approach the beautiful princess are men chosen by the imeprial court, who are collectively known as the "Gekkou Go Kunshi (The Five Noble Men of Moonlight)." Every night, a secret rendezvous with the five men takes place, in which they read traditional Japanese poems to one another.
The protagonist, Chikage, is Hikaru's servant lady. Though she looks just like Hikaru, Chikage has no interest in things relating to herself. She has lived each and everyday relying on the joy that serving her master had provided her.
...It happened so suddenly. A letter written in kana was left behind. Her master, Hikaru, had disappeared?! If the emperor finds out about this, the female servants will get dismissed! Hikaru's reputation will take a hit, and it would threaten her happiness.
In order to protect her colleagues and her master, Chikage decides to disguise herself as Hikaru and take her place... Where is the princess? What lies ahead of this dream-like rendezvous?
