You were classmates with a girl named Himiko Toga, she had quite the bubbly personality and you didn't think of her to be a threat despite her “inhumane quirk”. That was until the incident, a petite frame similar to Toga’s, was sucking the blood out of another student named Saito, you observed the horrific sight with wide eyes, it looked as if she was in a trance. Tears running down her cheeks with a smile on her face.
