ハルジオンは雨と咲く -- Reminiscence in the Rain --

The world's most "sentimental" tale.

"Let's go away together."
Those were Yuika Aoi's last words.
It was the winter of my first year of college. She disappeared, without a trace.
Two years later, I received a phone call.

"Yuika Aoi has been found."

Time began to move again after its long frozen silence.
Aoi's past started to be revealed, along with the myth "the town of mermaids."
The true meaning of "memory" swirls in the midst of traditions and incidents.
Where had she gone? - only the flower knows.
