User blog comment:Warmachine375/Starbiter Satsuki, a new full-fledged series?/@comment-27347138-20151220055800

I highly doubt it, as it has been around for quite a while now. Even if it were to be serialized, Mashima-san would need roughly 2 more chapters of it done before he could submit it for serialization. The story's last page also has the feel of ''The End" (maybe this is just a manga artist feeling...?).

Another possibility is that this is just a artist's blank/writer's block remover. The hardest chapters are anywhere from 2-10(actually getting the plot going) and 100+(running out of ideas).
