Deep Japanese personal-website culture from the late 1990s/2000s. キリ番 ('round number') refers to the milestone visitor counts (10000, 50000, 100000...) that web counters used to display, and キリ番を踏む ('to step on a kiri number') means 'to be the visitor who hit that round number'. The tradition was that this visitor would report it, and the site owner would thank them — often by fulfilling an illustration request (キリリク = キリ番リクエスト). A dense dose of internet-era nostalgia.
