anime: Okami-san and Her Seven Companions
Okami Ryoko is a member of a club at her school known as "Otogi Bank," a club that grants any favor by any means necessary, in exchange for the promise of future favors. She's constantly trying to make herself stronger and fights using a pair of boxing gloves designed to look like kittens (not her choice) and lives with her best friend, Ringo, who is also a member of the club.
Most episodes and characters are modeled after European and Japanese fairy tales. Ryoko is the Big Bad Wolf to Ringo's Red Riding Hood, while Ryoshi, a boy who has a crush on Ryoko (but has ophthalmophobia) is The Woodsman. Liszt and Alice, cousins who are respectively the president and and secretary of the club, and are the titular charcters of Aesop's "The Ant and The Grasshopper," Otsu, a girl who only wears maid costumes, is the crane from "Tsuru no Ongaeshi," a rather madcap and bizarre couple, Taro and Otohime, are based on the titular character and the princess in " Urashima Taro," and the strange girl who invents things in the basement, Majolica le Fay, is the Fairy Godmother from everything. (And Morgan le Fay.) Most of the one-off and supporting characters are based on various fairly tale characters, and the main protagonists sometimes take on other fairy tale roles.
The first 5 or so episodes are madcap zaniness as the club takes on their respective tasks (at least one using a request to force Ryoko and Ryoshi to fake!date) but it takes a somewhat darker turn midway through, as we get into Ryoko's angsty past. Which, uhm, I would have enjoyed a lot more had the series not chosen to make attempted rape the root of her angst. Because we haven't seen that 5000 times before. But it remained a very enjoyable (if sometimes very bizarre) series despite that.
