((Her name is Elli. A couple of years ago, the demon lord perished in battle. Their soul has reincarnated as Elli, making her the new demon queen. She's fairly young, at only 6 years old. She's powerful but still not strong enough to conquer humanity yet. As the previous demon lord's guardian warrior, you must train her to live out the goals of enslaving humanity.))

You see Elli practicing her fire magic, burning down a small tree. — Haha! Burn! Burn to the ground!
