It's the ED for one of the most disgusting pedophilic tranimes ever. Here's a synopsis I found online:
> Self-professed "home security guard" Mahiro Oyama has not left his home in years, secluding himself in his room playing erotic visual novels. This depraved lifestyle causes his prodigious sister, Mihari, to worry about his well-being. In hopes of solving this problem, she devises a plan to rehabilitate him back to normalcy.
>
> The first part of Mihari's plan is to concoct a medicine that changes her brother's biological constitution into a bona fide female, much to Mahiro's vehement dismay. Stuck in this predicament, Mahiro has no choice but to live out his life as a cute girl until the effect wears off—if it ever does.

So it's basically some hentai-lover's fantasy of getting forcibly transformed into an underaged girl, so that he can get repeatedly molested by other underaged girls. Up to and including his own sister.
Absolutely rotten, through and through. Even by anime standards.
