Idol A v01 c06 has been released, and for now it's the last chapter(who knows when or if volume 2 will ever come out...). You can find it on Mangatraders.
The volume contains even a one-shot collaboration between Adachi Mitsuru
and Takahashi Rumiko (of Urusei yatsura, Maison Ikkoku, Ranma 1/2, Inuyasha, Rinne fame...)
called My Sweet Sunday to celebrate the 50 years anniversary of the magazine where the two authors published almost, if not all, their works. It was translated years ago by the good guys at I Eat Manga and you can find that on Mangatraders too.
To it I've added the extra pages that where in the volume and renamed everything to be consistent with my releases (that were named to be consistent with chapters 1-3, IIRC). They used magazine raws at the time and you'll see the quality difference from the other stuff. Everything else is their fine work.
Seeing how the poll is going, I guess you'll read Slow Step next week, unless Gamushara makes a come from behind...
