Hibana

High school girl Tomori is dating an unstable boy named Inukai who likes to relentlessly bully Misato, a new transfer student. Refusing to listen to his friends' or Tomori's pleas to stop, Inukai's violent obsession steadily escalates. Is this from hatred, or for some other reason?

Meeting, drifting apart, and inevitably drawn to each other again... Sparks fly when they cross.
