What? First of all, the author Ai Yazawa is female, and she isn't dead, she had serious health issues back in 2009 which seem to be an autoimmune disease/some kind of cancer so she had to stop for multiple years and I suppose she either lost her motivation or her health still won't allow her to get back to work because she stated that she isn't ready yet to restarting the serialisation of this manga.
But yeah, she is still alive, so there is still a teeny tiny hope.
Is it completed?
