Nagisa is a friend of Tatsuya since their childh Nagisa is a girl in Tatsuya's class, a long time acquaintance, and would probably like to get closer to Tatsuya, but Nagisa has had violent allergic reactions whenever she is in Tatsuya's house ever since Tatsuya found a lost puppy (soon to be Crokette). She stays away from the house and the dog, effectively putting some distance between him and her, even though she loves him. Nagisa is shown to be dedicated and have great aestheticisms as she is trusted by Tatsuya to modify Shuela’s outfits
