Both protagonists are physically strong women. Nasty characters are excessively cruel and vicious, no matter where they come from. There's also lots of "almost gratuitous violence" against the victims in each episode, quite hard to stomach and so not for the faint-hearted. Then our héroïnes, start slowly with their moral little speechs sort of "Ijimae is bad, hurting the weaker is wrong..." and bam, they let rip at the assaillants despite their light calibre. Both are very repetitive due to the episodic format.
