Hey guys, I was wondering if someone could help me out on this. As a Teenager I saw a hentai I considered good at the time.
I got it over a torrent for a movie I wanted to see by accident, so I didn't get the name. My father found it soon after and deleted it, so I haven't kept any source material.

Sideinfo: it was dubbed in German, so I think it was not censored. I saw it about 2008 so anything past that time is not the source


Things I remember:
Protagonist is a cop/detective in a futuristic world, they have high functional Androids or A.I.
> he wears a white/grey cape most of the Time and has blonde hair
> He has a sister who is a cop. Sister gets raped by a bunch of thugs and inflated with a gas pipe up her ass, survives the assault but is taken to the hospital

> there are some Drugs involved, which, taken in the right order, give you superpowers. At least this is a myth... I don't remember any character actually achieving Superpowers

> There is an AI or a Robot involved, who is female and is actually the mind of a childhood friend of the protagonist. Of course they fuck.

> the whole plot took about an hour, maybe more.

Do some of you have an Idea what this might be? I know it's pretty hard to guess, but maybe some anon has seen it and remembers the name (I hope)

It's not Blue Sonnet and not Tokio Private Police (these are the only ones i found googleing some of the Tags)
