Jigoku no Hanazono

Funny how the IMDB summary refers to "office ladies are absorbed in the daily clique fighting", when it's actually all about real violence ( no guns though, just knives, sticks etc ).

Yes. Who knew that the clerks & admin women from those glass/concrete skyscrapers had a gang thing going ? It's a typically bonkers Japanese concept ( thank goodness ) as a quiet young lady ( Mei Nagano, reminding me of Korean actress Chae Soo Bin ) watches as a formidable newcomer ( the fiercely alpha Alice Hirose ) lays waste to a bunch of rival groups. There's more + a surprise or 2, & I was entertained at all times, though I do wish the central idea was embraced more energetically with the sorts of animations etc that enhanced "Real Girl" & "Love Is War" so well.

Nevertheless, it's cutely self-referential & definitely fun.
