Being a former Makai Priestess and armed with a Madō brush, arrogant and seductive in her current state, Amily has extensive knowledge of magical spells and uses blue butterfly constructs as her spies, eating them to acquire their knowledge, while also recruiting Horrors to serve Jinga's purposes. Amily also possesses the Demon Mirror, a relic that allows its user to increase another's power. Amily helps Jinga in his plan to revive Radan, even revealing to Ryuga and Rian that she and her husband are Horrors when the pair are sent to reseal Radan. While captured by Ryuga's group, Amily feigns regaining her remorseful humanity to trick Ryuga into entering the Demon Mirror and then escaping Gald and Daigo's custody to meet back up with Jinga.
