About the plot:
A story about a naive and kind-hearted boy named Hitori, who — by some mysterious means — ends up on an island full of (as it seems to him at first) girls... The truth about them comes to light quickly — but it's nothing compared to what lies ahead:
What is this place? How did he get here, and why? These are the questions he must uncover — along with others who ALSO got here the same way Hitori did. However, there's one catch: none of them remember their past lives BEFORE ending up here...

except for Hitori. Can they uncover the truth together? Why were they chosen — and why is Hitori the only one who remembers? Will the others treat Hitori with suspicion for being the only one who kept his memories — or will they see him as their salvation? Should they seek the one behind it all — or will that someone come to them first?...
