Glenda stands guard over a relic from the Cleansing, left specifically at Lake Kannawa. This relic acts as a vessel holding information about Cain, the father of demons within the series' lore. She possesses long, light-colored hair reaching her back and similarly light-colored eyes. Her personality is distinctly childish, often expressing excitement with the interjection "Da". Glenda can transform into a giant dragon, an ability typically triggered by fear or an active desire to protect someone, with Yuiri being a particularly frequent recipient of this protection. During the events of the anime's third season, she summons Cain's Legacy from the node, an action crucial to defending Itogami Island against military forces of the Holy Ground Treaty.
