Everything about Naoya's life was as regular as possible, except for his inexplicable talent to be good at almost anything he tries to do, as well as a weird dream that he has been having since his childhood, showing him unfamiliar people, places and languages he has never encountered before. His talent has made him lazy and unmotivated, spending all his time with his hobbies and friends to bring back some sort of satisfaction in his life.

However, a strange encounter with a mysterious old lady sends him into a fantasy world, reigniting a sense of purpose and excitement within him as he eagerly sets off in his grand adventure.

But not everything are sunshines and rainbows in this world, and soon he will discover secrets that he would've been better off not knowing.
