Not gonna lie, while I still like the transformation in 103 - 111 it feels like it's missing a few pages and could've been a bit longer. Like the hair for example going from short to long in the very next frame.

Base +10

I should probably add one more in between panel for the hair, as for the body transformation panel, the current transformation is not the final look and will transform more over time, sometimes reverting back a little. So you will see more transformation pages in future chapters.

Besides that, in the past month, I've been experimenting with tools in Koikatsu, and I managed to figure out how to do more interesting transformation sequences, which you will see in future chapters, it will take some time to appear on the free release, but I'm sure you will enjoy it ;)

Edit: added two more pages in between the hair transformation.
