エルフィー

She is an elf. She is good at magic and a reasonably good swordsman. She is one of the former demon king's lieutenants.

She has a polite tone of voice and a calm and collected personality. When the former demon king was alive and well, she was in a secretarial position at but was clumsy at the best of times.

She was the one who summoned Akari by mistake in the demon king summoning ceremony.

She speaks in a very relaxed tone to everyone, but talks to Akari in an overbearing tone.
