|Nayu Shinozaki (Shinozaki Nayuu)|
|Relatives|| Taeko Shinozaki (mother)
Tarou Kanda (cousin, presumed step-brother)
Nayu has the standard appearance of a young teenager. She is much shorter compared to Tarou, reaching around his chest. Nayu's dark hair is short and neatly combed. She would often be seen wearing a casual outfit whenever she makes an appearance
Nayu considers Tarou her brother and is apparently holding some feelings for him, often calling him "onii-chan", though she has never revealed anything beyond that. Being unaware of Tarou's supernatural abilities, Nayu would often take his food/snacks away from him in fear of him "growing fat" (which he couldn't).
