Important note. I only know English. So I have zero knowledge about ether language. and Im using Google Translate. so take this with a pinch of Salt. However if you know Japanese or Malay, or know what language Zer0finix is speaking. feel free to let us know.
Zer0finix has done done comic dubs of her own character. even claimed to do Japanese versions. ( sadly i have no evidence of this claim, so Take this with a pich of salt. once i find one Ill be sure to update this) however when you take diolouge and run it through a translator. it does not add up. nether does the Malay. which is the official Language in Brunei. However Brunei has other languages and Dialects. So who knows for sure.
now is she lying about a language? its possible, but I dont have any way to prove it. just speculation.
Now if she is why would she do it? Probably to attract the weeaboos. that be my guess. but We cant know for sure. all speculation.
