I was getting ready to ask you guys
(jeepuroppu no minasan) if there was a name for the kind of wispy tendril-y side locks that Airi has. Then I remembered that there's this magical thing called Goggole or something, and
apparently they are called "shokkaku" (触角) which means "insect antennae." An oddly gross yet visually evocative name for such a cute hairstyle.
