I've noticed that pretty much every single girl named Akira in manga is ridiculously hot and/or cool? The one from Canno's Polycule series, the one from Taiyaki's (first) mothercon series, the one from the Revue Starlight mobile game, and like twenty others I've probably forgotten. It seems to be a name that guarantees chadness.
It's an unisex name, gender-neutral, you can give it to a girl or a boy.
Because it's both a boy name and a girl name, the trope is that it carries an androgynous quality, especially for a girl. She will almost always be a tomboy or a cool femme, and make other girls go doki-doki in excitement.
For whatever reason, it doesn't work the other way: a boy named Akira most of the time will be a vanilla chara and won't be feminine or anything.
