If this is truly Dashigara, it must be pretty old indeed, as it does not look at all like him/them.

Any way we could get a Torrent?

@OmegaSin : I understand your doubt, but there is a proof ! :-D
Take a good look at the contents of page 4.
On the UPPER LEFT CORNER there is the title "Before nightmare".
On the UPPER RIGHT CORNER (just next to Sophitia's head), there are 4 kanjis in a black box.
Those Kanjis can be read as "Minpei Ichigo", which happens to be the other name of Dashigara 100% ! :-)

Yeah, I know it doesn't look very much like him but, hey, This was made several years ago ! (probably around 2005).
Good old Dashigara was probably just starting his drawing job.

I always had a doubt this was an early work of Dashigara 100% because of 3 things :
1 - the way Sophitia was drawn reminded me Ayane in "Never any Volleyball" and "Ayane Gaiden".
2 - the fonts Dashigara used to write the text inside and outside the balloons are always the same.
3 - the male character looks a lot like the "average fat and ugly Oji-san" that Dashigara always draws as a sexual partner for his heroines (with the only exception that he usually draws them without ANY facial expressions).
