エクリア・ベルトワーズ

A girl who runs a general store on Vanaheim island. Despite her adorable appearance, she has unimaginable prowess in item identification and item enchantment. She helps Lyiene identify items found in the dungeon and their strengthening through enchantment.

She visited the abode of Lyiene's teacher, knowing of their fame as Magical Girls who defeated the Witches, to seek help in ridding Vanaheim's dungeon of the monsters within.

 Lyiene asks how Ecria is so talented at item identification and enchantment. Ecria answered her parents ran the store and were experts in their respective fields. After watching them work, she awakened both of their talents allowing her to take over the store after her parents passed away.

Ecria's form is an illusion, her real identity is the last surviving Witch "Alice". After the great battle with the Mahou Shoujo decades ago, she was critically injured and forced to flee to Vanaheim island to recover. In order to gain the sperm of male adventurers necessary to generate more magical energy, she spread the rumour of "Alice's Legacy" to lure countless adventurers to the dungeon who would succumb to the dungeon's monsters and serve as sustenance for her recovery.

As a Witch, she is able to form a contract with monstrous beings from the underworld like Minotaurs compelling them to serve her as guards. 

Although pleased Lyiene has grown strong enough to reach the dungeon's depths, further adding more magical energy to her heart which was to be used as the final ingredient in her immortality ritual, Alice loses the final battle against Lyiene. When she attempts to summon the boss monsters of the dungeon's upper levels to deal with an exhausted Lyiene, her own fatigue and depleted magical reserves cause the summoning spell to go awry. Lyiene's final struggle eventually distorts the spell into a one-way portal which consigns Alice and her servants into another dimension. An exhausted Alice is then set upon by her servants who have gone berserk and see the depleted Alice as a tempting source of magical nourishment.

Ecria's true identity is eventually revealed when she disappears permanently and magical tomes relating to the Witches are discovered in her shop. /
