Aho Girl or “Clueless Girl” is about all of the ways Hanabatake Yoshiko is an idiot, as seen from the perspective of her neighbor and long-suffering caretaker Akutsu Akuru. In under thirteen minutes of airtime, A-kun and others call her an idiot thirteen times and he assaults her a half-dozen more as punishment for being so idiotic.
If that sounds really one-note, it’s because it is. However this double act in which A-kun is the straight and Yoshiko is the foil sort of succeeds for two reasons: despite her idiocy Yoshiko has a great deal of performative range (thanks to her seiyu, a game Yuuki Aoi) and the bits and jokes are numerous and frequent, leaving scant time to stop and ask yourself why you’re watching.
