@Aradiel They actually already existed in the form of the author's "4-koma Collection"(i.e. the pre-serialization version)... I was going to say, but apparently that was only partially true. The later ones pre-serialization, have indeed only been touched up a little, like this one (pre-serialization to the left):
The earliest chapters are fully re-drawn though:
I suppose they didn't hold up to the standard of the later pre-serialization chapters/the serialized manga. Not that I mind, seeing these very first chapters with prettier art is sweet.
