The young leader of the 30th Division of the Demon Slayers， the Order of Light. When a mysterious army began their invasion， Joshua was summoned to return home from Ishgria， a land ruled by demons. Rushing to the scene of the action， he ambushed the general of the enemy army and prevented them from invading the imperial capital. Afterwards he continued defeating foe after foe in his usual impulsive manner， which caused a bit of a headache for the Summoners of Old as they struggled to keep tabs on him. However， regardless of his recklessness， no one can deny that he has proven himself time and again as one of the most powerful members of Summoners' Hall.
