Ryoko-san and her friends at the Otogi Bank help classmates with their problems, in exchange for their help later on.

Once upon a time, the studio behind Toradora. and Shakugan no Shana created a fable-minded story full of fairy tale tomfoolery. In this amusing rendition of the wolf and the hunter, Ryoko and her friends form Otogi Bank: a social club that helps classmates get out of grim situations. When a boy joins the group to prove his love to Ryoko, will she allow herself to have her own happily ever after?
