Bikini Warriors is an anime about two things: buxom fantasy heroines dressed in nothing but bikini armour, and making fun of some of the most prevalent JRPG clichés.
Let's be clear up front: There is a stupid amount of fanservice in this short-form anime. So that alone may move it off (or onto) your watch list.
However, what keeps me watching each week is its comical jabs at JRPGs. Each four-minute episode is focused on one cliché or another. The first episode is the most obvious one: chainmail bikinis (and the absurd notion that they provide any protection at all).
The second episode deals with the odd economic disparity existing in the lands heroes visit -- i.e., the reward for saving a kingdom quite often being less than the price of a night at an inn. The third hits on an obvious target: JRPG heroes are basically the world's most blatant thieves.
My personal favourite episode so far has been on the useless stockpiling of elixirs -- I mean who doesn't end each game with a dozen or so, stashed away for an emergency situation that never comes.
Long-time JRPG fans will likely get a good laugh or two out of this anime, if they can come to terms with the fanservice, that is.
