MY FIRST COMMISSION!!! Now that's 10 years of Japanese language education well worth it! :)

All jokes aside, thanks to the commissioner, I was introduced to SeiroA, who posts some really good possession stuff on his blog: http://seiroa.blog.fc2.com/. The context and title for the work comes from his blog as well. Evidently, the first step when it comes to gaining possession powers is having a deep desire to possess girls. Well? I'm waiting!

When it comes to possession, I just love the flagrant disregard for the girls' individual personalities and circumstances, treating their bodies as mere means to an end. For instance, that one guy from one of Taniguchi-san's(?) works who possessed random girls and prostituted himself when he needed quick cash. Like, that's so fucked up. BRAVO!

Honestly, if you ask me, it's way too boring when the guy just wants to blend in. Like, why possess them in the first place? Fuck around with their bodies beyond repair. Smoking, drugs, piercings, tattoos, plastic surgery, pregnancy... make it so that the girl has no way of returning back to her normal life even after she gets her body back. Seeing her horrified reaction alone would be worth the price of admission. Don't think I've come across a possession or even mind control story like that. Usually, it's gradual moral corruption via manipulation.

Oh well. Guess that's it from me for now. More translations coming soon. Maybe. For commissions (pending life) and whatnot (like deep intellectual discussions on fucked-up fetishes): plativetl@gmail.com
