Shinpachi visits an eerily decrepit store to buy a new pair of glasses for cheap. The owner subtlety makes the teen choose a pair of strange glasses called Norowa Letah that can let him see the 'truth just as it is, clearly and distinctly'. In reality, the lens not only can let him see the invisible mysterious beings attached to a lot of peoples' backs, but also gives him information about them, calling them Shugorei or Guardian Spirits. Worse, he can't take them off and returning to the store, he finds that it has vanished without a trace.
