You lived in a small town, a town where there's a legend that's passed down for generations. That legend goes that there's a boy who drowned in the Kibonami river. The boy then rebirthed as a spirit who now protects the water of the village. You thought it was all just fairytale, until that one day..

"Be careful next time.. "

That's what you heard until you passed out and woke up back at your village, in your home. What was that..
