Shinobu Oshino is the heroine in Nisio Isin's 'Monogatari Series' light novels and their adapted anime. Her human birth name was Yaserola. About 600 years ago, she was a girl of noble birth, known as a beautiful princess because of her beauty. The path she walked would become a mountain of corpses. 598 years ago, she was transformed into a vampire by the Vampire Lord Suysaid, earning the name "Kissshute Yaserolarion Heart Under the Blade," and earned many powerful titles such as "iron-blooded, hot-blooded, cold-blooded vampire." Now, she appears as a young girl of about 8 years old, with fair skin and golden eyes. Having lost almost all her vampire powers, she even lost her name for a time. Later, due to her achievement in sealing the barrier cat, Oshino Meme named her "Oshino Shinobu." She is proud and proud, speaking in the way ancient people spoke. Although she appeared like a young girl, she was essentially a vampire and completely unguarded against eroticism. She shares a deep bond with Koyomi Araragi; she was Koyomi's master and later became his relative. The two depend on each other and have sincere feelings. She likes Donuts, Black Tea, and Shogakukan's comics. Although she has lost most of her power, she can use some vampire abilities by her side, such as energy absorption, hiding in shadows, and material creation. Drawing Li's blood can also restore some abilities.
