Her previous employee Patiricia Garlond is largely controlled by the Grimoire Lust. A demon is sealed in this grimoire and can now influence its surroundings again. Only with the intervention of the magic book Dante can Patricia initially fight back. However, when Patricia unexpectedly acquires fresh magical sources, she counterattacks the academy stronger than ever.
