Well, here we are again, so soon after the last one: they’ve made yet another comic where the punch line in Japanese heavily depends on the Japanese language. The original dish that Ladiva was serving up was called ajillo, a Spanish condiment combining garlic and a chili pepper (or written in Japanese, ahiijo, which is... not actually how it’s pronounced, since a double-L makes a “y” sort of sound in Spanish, but that’s neither here nor there). Seox wondered why it was called that, and Keehar made up the story that it was because women (josei in Japanese) eat it while it was still piping hot, and exclaimed ahii! when they found it to be too hot, thereby being ahii-jo, or “ahii women”. They then turned to Lyria, who, rather than exclaiming ahii, just sucked the whole thing up with the sound effect ahyuu, making Jamil remark that Lyria is an ahyuu-jo.
Obviously, this joke wouldn’t even remotely work in English, so I went digging for another similar dish that I might be able to wrangle into an English pun, and eventually came across mole de olla, a Mexican soup (olla is pronounced roughly akin to “oh-ya”). It was a dish served in a bowl eaten with a spoon, was Hispanic in nature (though, yes, I know, Mexico is not Spain), and I could see making an English-sounding exclamation out of it, so it seemed like it could work. It worked less well for the secondary joke in the last panel, but, well... what’re you gonna do.
