@The Goat is Watching to be fair Gyaru is a style/lifestyle so it’s not really restricted to Japanese work, as long as someone fits the requirements to be Gyaru the tag is warranted. Though in this case I’ve got no clue on why the Gyaru tag is here cause no one in this comics looks like one.
Love Olivia finally having a nose, but kinda confused on the timeline here. I think it makes more sense for episodic adventures to have Amber and Olivia just be coworkers, but I was genuinely happy for them when they had their virtual date in Part 5. Hope to see more romantic stuff from them.
