Previously, we have proposed a new computer oriented methodology for a sentence structure analysis based on a linear space theory. Its result has clarified that any literatures are composed of the control led flow of the exciting and quiet sentences, sections and chapters. The flow mechanism of these sentences represents not only the identity but also feeling of the authors.
In the present paper, we apply our methodology to the Kenji MIYAZAWA's work focusing on the key words selection. As a result, it is revealed that the story "GINGATETUDOU NO YORU" is characterized by the actions of two boys and the word "2". In addition, It is pointed out that a small variation of the key words may become an important factor in the story.
