I don't normally post requests, but this is a request for something I've simply been unable to find. It's a work by Senno Knife (a.k.a. Senno Naiff, Senno Naifu). Senno Knife seems to be a fairly popular mangaka, so I wouldn't think this would be
that hard to find. Anyway, here's the G-Zone link:

Looks pretty cool. I ran the text on that page through BabelFish and it looks like the girl shown there starts to grow at a rapid pace because of some weird medicine she took.
On a side note, this is another one I noticed at G-Zone that looks interesting, especially if you're a mini-GTS fan:
