Trust me, the image I've used is the least offensive thing this show has done.

Abunai Sisters is a series of CGI shorts revolving around the lives of real life celebrities Koko and Mika Kano, the two are nothing more than tabloid celebrities who appear everywhere more for their sex appeal and glam rather than actually being proper celebrities with tabloid, think Paris Hilton with a boob job.
The actual anime, although calling this an anime is kind of offensive, sees the titular girls play as secret agents who protect the source of their power known as the Boobie Stone from villains. The gem giving them really busty bodies and able to manipulate them further by weaponizing the over sized mammaries.
The production is cheap and nasty, the sisters themselves look like even sluttier bratz dolls, the plot basically boils down to how quickly they can weaponize their tits and it was dubbed into English just to rub salt into the wound. A benefit to subtitle versions is not hearing how bad the script is.
It's original run was cancelled after two episodes, even Japan thought this was terrible. The only way I even knew about this series was while searching for the worst anime of all time and this would easily be a contender.
Final Verdict: Someone thought this was a good idea, someone greenlit this show, someone actually dubbed it in English, this is the truest definition of a dumpster fire.
