Kiriyama Seito, an ordinary high school student, stumbles upon the scene of a kidnapping during summer vacation.
Using his quick wits, Seito succeeds in freeing a girl, Luna, who was about to be kidnapped.
After rescuing her, he hides her in his house for a few days.
After that, she is picked up and everything seems to be over without incident.
Little did Seito know.
The girl he had saved was actually a princess who had come to visit on a secret visit, and he had been noticed by her.
The two were to cross paths once again.
Luna comes to study abroad in Seito’s class.
