I finally caved and bought the disc for PNST-002 and ripped the video.
This is my Tachibana Nagisa folder, instead of reupping vids already available in the main megas I've just listed the other movies as .txts. Also included are archived pics from a now scrubbed twitter account and LIBE page. I'd also appreciate if anyone knows of any other content of theirs I am missing (I'll probably try to buy it)
Edit: I've been informed in the otokonoko jav thread there are more films. Definitely going to try and get the crossdressing ones ACSM189, ACSM209 and ACSM234.
