The Asako Inquisitors were founded the third century in response to the corruption of Isawa Akuma by the Council of Five, to combat maho wherever it might arise.
The Asako family assumed responsibility for overseeing the Inquisitors, as the Asako were often left to their own devices by the rest of the Phoenix. The Inquisitors sought to punish and destroy any instances of maho and corruption, and could be easily identified by a tattoo of a strange eye which they bore upon their palms.
