Can't believe there's no thread for this.
Mano Erina plays an ESPer who can't quite get her powers working right. After escaping from the super secret facility she was confined to, she's tasked to explore the world and to become a full ESPer in the process (she's only half esper, as one can probably surmise from the title). S/mileage plays a group of girls who have their own broadcast radio show. The show also has guest appearances from other H!P girls, with Takahashi Ai, Michishige Sayumi and Niigaki Risa appearing in eps 1 2 and 3 respectively.
I think my favourite has got to be episode 2, with Sayumi. She starts off as an incredibly annoying person, but to the end you can see that Mano managed to change her by being nice! Also, I couldn't stop laughing at the burned bento. Episode 3 paled in comparison; Risa just isn't very funny..
There's only 3 subbed eps out at the moment done by
Hyakupa subs, but they're pretty good quality subs.
