The nickname "The Gate Guardian" is not exactly an honorable one. Valeta, who was responsible for overseeing the novice nuns at the Aradal Snow Mountain Convent, was known for excessively controlling the novices, often found guarding the door. Out of resentment for her strict rules, the novice nuns gave her the nickname "The Gate Guardian."
When the Rift Crisis began and they moved to Earth, Valeta returned to active duty, fighting on the front lines. She devoted herself to protecting the novice knight-nuns, and the nickname "Guardian of the Gate" gained much more honor compared to before. After arriving on Earth, the order no longer recruited new knight-nuns, leading Valeta to hope to serve as a Vanguard under the Human God.
