Sister Princess

Wataru Minakami, an honor student, misses out on his preferred high school after a computer error derails his entrance exam results. Soon after, he learns he’s been admitted to Stargazer Hill Academy, located on the enigmatic Promised Island, and is sent there at his father’s urging.

No sooner does Wataru arrive than he’s surrounded by twelve bright, endearing girls—each insisting she’s his younger sister. As he begins to navigate life on the island and form bonds with his unexpected “siblings,” questions emerge about the circumstances that brought them all to Promised Island in the first place.
