She speaks in single words like "Confirm," "Affirmative," or "Negative," giving her an alien-like feel. A Luus, a merman of the deep sea. She can move freely between the deep sea and land. They are monsters that intentionally cause Gates in the deep sea—where humans cannot reach—to stampede so they can eat the monsters. Her true form has a head like a deboned fish that splits into three parts, filled with rows of shark-like teeth. She has long fins, and her lower body consists of tentacles rather than a tail fin. An appearance that would make a human lose their mind. However, Gurugeflam is a heretic among her kind and maintains a human appearance. She is the strongest, with each individual of her race being S-class (Dragon-class). Gurugeflam is S+ (Ancient Dragon-class). Gurugeflam can freely use ancient magic. Every word she speaks in her clipped manner is of the ancient tongue. It is simply translated through her will so it can be understood. In other words, anything she says as a word can be used as magic. For example: 'Heal', 'Absorb', 'Restore', 'Cleanse', 'Transfer', etc. Though she speaks in single words, she is highly intelligent. She has a human friend named 'Del'. When she gave Del a deep-sea mana stone as a gift, Del gave her a large amount of seafood in return, which her kin rejoiced over as a feast. Del is a peculiar human who can see monsters.
