The Azure Grimoire isn't the True/Real BlazBlue (Book of Blue Blaze). In reality, it's just a Cauldron. It was made by Terumi, so that he could chip away a portion of the Azure, but it gone berserk and started absorbing life and souls from the world without restrictions (and thus became the Black Beast). It's unknown when he made it, but it's first known use in the series, was during the experiment in which the Black Beast appeared.

According to Remix Heart (the current translation of it), Nine knew about the Azure Grimoire and even planned to create the Burning Red to pair up with it, so it's possible that Terumi already had another copy at that time (or merely was forced to reveal to her what it is and how to make it). On the other hand, seeing how surprised Nine was when Terumi used the Azure Grimoire to open the Cauldron in Ishana, does indicate otherwise (at least according to CP:6H-EP1, though they omitted to mention that he used the AG).
