Surprise! The strips on panel 3 are from "4koma Diva! Gaiden" and "4koma Diva! Magical," both spinoffs of this comic. There's also another spinoff not shown here called "4koma Diva! Mystery Theater." They are all very short with only 13, 8, and 4 strips respectively. I will post them after I finish posting the main series. Almost halfway there!
