Y'know, I have this little bit idea for a doujin : It takes place after the ending of OreImo, where Kuroneko, still bitter inside after being rejected, finally snapped and come to Kyousuke wearing a wig and Kirino's uniform, and trying to seduce him with her eyes being hollow and yandere-esque.
Or maybe instead of Kuroneko, it can be Ayase who did it.
