A third year Zuellni Military Arts student, Nina is the strong willed captain of the 17th platoon. In order to keep the 17th platoon from being dissolved, she recruited Layfon after he was forced into the Military Arts section by Karian. She is formerly from a rich household from a different city. However, she escaped that city, because she felt like there were other things out in the world that she had to protect. So, she ran away. She supports herself by working along with Layfon. She is a powerful fighter who considers weakness a sin. When she was younger, she was almost killed because of saving a young infant fairy. Thankful because of her, the head fairy sacrificed herself in order to save Nina. Therefore, she seeks power to protect the weak.
