I'm not interested im this subject (male zako), but Danial Zako is correct to post this here. The word "zako" doesnt specify gender. It translates to "small fish" and is commonly used in japansse to refer to "disposable minions", regardles of gender.
There could be another catagory for it to be in (like "guru"??!!) < no idea what that is,
but it's the same as saying "zako" is the same as "henchwomen" or "minions". Countless subdevisions of basically the same thing.
How do i know "zako" can be male or female ? Anyone who's been on this forum for a while and seen my posts can probably imagine the rediculous amount of time i've spent searching the internet for new (female) zako content. And yes, a huge amount of results for "zako" comes up with male goons (mostly video games)
In the end, i dont see a problem if people want to post "male zako" content in its own thread. If you're not interested in the subject, just ignore it (which is what i do with any thread/post im not interested in.)
