Chanu Academy is a prestigious school for Summoners, humans with bloodline contracts to creatures from an alternate dimension which can be called upon to battle and compete for fame. Acceptance into Chanu Academy is based on bloodlines and outstanding ability. Seo Jimin has the bloodlines... but lacks a contract with any Summons. Navigating Chanu is going to be difficult if she doesn't find a partner fast - and maintaining one may be even harder.
