I can greatly divide the literature activity of Jun Ishikawa in the 1950s into two. One is a flow of so-called revolution novel to see to ``What is the revolution`` "Hawk" "Coral" "Thunder" "Rainbow" of the early 1950s and "Falling of blossom" "Aster story" "Hachiman omen" "Asura" in mid-1950s, "Hakutogin" and "A shadow", then in the late 1950s catches the "Secret" "Mirage" "Miraculous medicine 12jintan" "Apparition Ishibotoke memorial service" "Liver of the fox" , and is plot in the false history to see it to "Brides after the death" with a "Nude woman altered phase" "Kiju dojo" and fantastic novel group. He in particular confronts the system and order, power and shows the mind exercise that I sometimes fight in figure - alone in a group and challenge of fighting people. And it is usual to be over by a method to indicate a flow of the mind exercise that one exercise ends and accomplished as a fight new again. This report puts the principal objective in showing the grounds that you should classify into locating the reason and the revolution novel group. Thus, of meaning of "the shadow" named as "a shadow" and because read relations there revolution novel with "Tosu Shogo" prove what a meaning can read enough, and it is a purpose of this report that "the shadow" proves the thing that is one of the revolution novel group.
