Sasaki Oyuki is a man who has lived for over two thousand years.
At least, that's what the truth says.
Sasaki, however, claims to be eighteen.
With no clear memory of his past and only one goal in mind, Sasaki travels across the mortal world in search of The Truth.
Along the way, he encounters strange people, forgotten places, and mysteries that seem to follow him wherever he goes.
But the further Sasaki travels, the more fragments of his past begin to surface.
A past filled with secrets.
A past he may remember.
And with every truth he uncovers, another question emerges—
Who is Sasaki Oyuki?
And will he ever find The Truth?
