My senior at the mountain, who was an employee of a precision equipment manufacturer, said that Kumada of the 3rd Run was considered a weirdo even at his workplace, which was in charge of prototypes. That senior also died in the mountains. There is oxidation on the edges due to aging, but it has not affected the pages. The cover's vinyl cover has shrunk and is creased.
