How Long Does It Take to Watch Okami-san and Her Seven Companions?

Ookami Ryouko is a spunky and, by some accounts, rather manly high school girl. She is tall, speaks in a traditionally masculine way and is very proficient in fighting. Ookami-san's best friend is the small and high-pitched voiced Akai Ringo. Incidentally, the two are rather flat-chested, a fact the Narrator (voiced by Arai "Kuroko" Satomi of Railgun fame) is all too eager to point out.

Ookami and Ringo are members of the Otogi Bank, a club in Otogi High School that assists students with their problems in return for their assistance on a different problem at a later date; thus the Otogi Bank is effectively a loan institute for problems where you can take out a loan for a solved problem but you have to repay it sooner or later.
