Narutaru (Shadow Star): Mamiko Kuri

She's an quiet and mysterious girl who was taken under Sudo's care when he found out she had a shadow dragon, though it is never clear how he discovered her. She does not like to wear clothing, preferring to be naked when indoors and only using a flimsy dress without any underwear while outside her home or school and footwear like sandals is her second least favorite type in clothing aside from panties, given that she only wears shoes in all of two appearances. She became friends with Shiina in Banda Academy and they both found out they process the same shadow dragon, Sheol. This is from Episode 7.
