To Naofumi, Atlas is like a young child who forcefully tries to approach him since her arrival in Rock Valley. Naofumi speculates that the Yggdrasil medicine that has given her the miraculous recovery may have made her infatuated with him as a side-effect. Despite being pushed away by him due to her forwardness towards him, he sometimes trains with Atlas and even allows her to join him on his ventures due to her skills on par with Raphtalia. However, she cannot replace Raphtalia as his moral compass because her infatuation with Naofumi makes her support even his most evil actions such as his attempt to kill Ren.
