This is a set of issues 99 and 100 of Kurashi no Techo. Kurashi no Techo has a unique system where the first editor-in-chief, Yasuji Hanamori, left behind 100 issues to represent a century, and this system is still alive today, so there is no issue number 101. Therefore, issue number 100 of the 4th century represents 400 issues since the first publication. Thinking about it that way, it's quite moving. Thus, issues 99 and 100 are the issues that span the century. A special feature commemorating issue 100 is also included, so please take a look if you are interested. - Title: Kurashi no Techo 99 - Issue Number: 99 - Publication Date: April-May 2019 - Title: Kurashi no Techo 100 - Issue Number: 100 - Publication Date: June-July 2019 These were stored at home, so there are some slight creases on the corners of the books, but there is almost no dirt or damage to the main body of the books. Please consider purchasing only if you are satisfied with the condition. Thank you for looking.
