Oshino Shinobu
Oshino Shinobu is a former strongest vampire who has lived for over 500 years. She currently resides inside Araragi Koyomi's shadow and can change her form by sucking his blood. Normally, she takes the form of a little girl with distinctive yellow eyes, sharp fangs, and long blond hair that curls outward at the ends. Her personality is marked by arrogance, often speaking condescendingly to others. She has a unique physical connection with Araragi Koyomi, her master, which allows them to share emotions and senses.
