Aji woke stiffly in darkness. He tried to search for light as he gropes his way out. But he discovers something that might have been the end of everything. He has no identity. He spent his day wandering around. Yet he can’t remember anything. He’s so occupied trying to remember everything. Figuring out why he woke up in the midst of the autumn. He just can’t seem to get his mind off those things. But he met a girl, Ayu. She was a very nice girl who is helping him unfold the history. Will he finally be awakened?
