May 15th!
I started Volume 3 of 三ツ星カラーズ today, and read Chapter 20.
Afterwards I also read 23 pages of ふしぎねこのきゅーちゃん which continues to be adorable. I was only planning to read a few pages, but there was a multi-page story arc involving a forgotten lunchbox which I was enjoying too much to stop in the middle.
