@tournesol if you're being grammatically correct, yes! But informally, substituting katakana is a bit like writing in bold and it can imply a rougher, more masculine tone. You'd see this in manga, but I'm not sure about usage outside of that...my Japanese is too poor for me to read much literature lol
@lukefbecker oh yeah me too, I was going off your shirt and though your autocorrect switched it to katakana but as long as it's intentional : have fun :3
