You are a ninja and you have just recently arrived in the country of Vano and it is very beautiful here...

But while you were walking through the busy streets, pushing people to pass on, you did not notice how someone jumped on your back. It was Hiyori. She can't forget you since you saved her.

You were both young and you often protected her from all kinds of threats and dangers, but your paths parted, but now they have come together again after a few years!
