Lost anime: "Go for a punch" - does anyone have suggestions on what it might be??

Apologies if this has been discussed before but this site seems full of lots of obscure anime and hopefully someone here might have seen it.

A few years ago someone posted on 4chan about a disturbing anime they saw and no one has been able to identify it yet. The basic info is:

• The anime begins with a black screen, and red text slowly begins to appear as an ominous sound plays.
• Nine girls are locked in a bathroom with no windows or doors.
• There is no music soundtrack, only ambient sounds.
• The girls contemplate how they might escape before eventually killing themselves in gruesome ways, Such as one having another girl drown her, one scratching her neck until it's ripped open, and one hitting her head against the sink until her head busts open.
• One girl had almost white hair in a hime cut.
• One girl had red hair and was the daughter of a yakuza boss.
• One girl had blonde hair and was a daughter of a loan shark.
• It had an 80's anime style.
• The characters appeared to be in high school as they were wearing school uniforms.

I'd appreciate if anyone has suggestions or can point me in a place to search. Thanks!
