Between scrubbing the toilets and blackmailing the student body, the janitor in this well-done piece of Japanese animation is a busy man.
You'd think being the only guy at an all-girl school would find an easier way to score campus coochie, but he revels in being an emotional sadist and the girls of the school serve as his masochists. There's lots of things that will make viewers of couples fare very uncomfortable, but nothing fans of Japanese fetish material would find surprising, such as scenes dealing with enemas, urination, defecation in addition to coerced sex through blackmail - though nothing is really shown, just hinted at.
There's also the usual draws of Japanese anime set in an all-girls schools - the Sailor Moon-ish uniforms, the latent lesbianism and hair colors that look like they came out a Manic Panic bottle (purple, green, pink).
The main draw, however, is the voice talent, with Asia Carrera and Rayveness. Casual fans might not be as interested, but hardcore fans will be sure to snap this up for the novelty aspect of the video. The voice direction overall is emotional, and not flat and overly-wordy.
A nice distraction from giant robots beating the crap out of each other.
