The manga shows more of Kasumi Asakura's past as a 14-year-old child assassin in service of a terrorist group called ALICE prior to joining up with ASALLT.
Anime News Network's review of Rose Hip Zero have positive as well, stating that the manga was well done for using the "buddy cop"-style of relationship,[5] similar to the Lethal Weapon series done in the 1990s,[6] though Anime News Network critiques it for having Kasumi use non-lethal bullets in her weapons, which has "no place in a gritty police drama."[5] Teenreads.com has even said that Rose Hip Zero is a fine read especially to those who prefer "shoot-'em-up action movies, police dramas, or even the flying-fists of Jackie Chan."[7]
