The last available chapter, Mezzanote (C84), may actually be the first. From a note which I presume comes from the author. I imagine it is him and not someone else who redrew it because it looks like it's attributed to him, and the art looks like his.

From Mezzanote:

The first Bikko book, there was something
like that, wasn't there? I didn't have it
before, but I obtained it through a strange
way. So, at that time, I thought of redoing
it. Of course, I didn't have the digital
data. Also, the quality would be rough if
I were to scan it. So, in the end, I redrew
the whole thing. So, there you have it,
Bikko's debut manga.

If there was an angel who would come
down upon a novice artist, I'm sure the
angel would be a girl like this.
