A series of 18 illustrations by Shuno to celebration Hatsune Miku's 16th birthday. The first and the last feature Miku's 16th Birthday design. The 16 remaining, matching the year of the birthday, are divided into 4 sets of 4 seasons-themed illustration.

The illustrations are posted on Miku's birthday, August 31st. On Weibo, they're gradually released every 6 hours through out the day. The opening illustration is released at 00:00. The first set is supposed to be released at 06:00 but Shuno woke up late so it has a 13 minute delay. The second set is released at 12:00. The third set at 18:00. The fourth set at 24:00. And finally the ending illustration at 00:00 again, of the next day, which is just the same thing as the 24:00 of the post before.
