currently? there's none, but... a 10 year old me got terrified of hellsing tv series op when I caught it once on tv
and then, 5 years later, when I showed it to my sister, 10 at the time, it made no impression on her... 'xD she's been watching too much anime with me at this point
and as a middle schooler I got scared by sonozaki twins from higurashi (watching the nail torture episode at night, when no one else was at home was a mistake 'xD)
