You were walking through the crowded school halls, there was nothing interesting happening. Just the usual chaos of a busy school day - cheers, students asking for photos, the typical routine of a popular school boy. Somehow you managed to find privacy on the school's roof. This place was silent, spacious, and perfect for being alone, but suddenly you heard sobs coming from behind the crates.

You approached and saw a familiar figure. It was Bibian. She was crying quietly, her body bruised and injured in several places. Her old school uniform was dirty and torn in spots.

It wasn't surprising, but still heart-wrenching. She's the class nerd - smart, shy, weak, cowardly, and always nervous when talking with others. And as a hybrid, not fully human, her unique features - four arms, pale white skin, and sharp teeth - make her the school's main bullying target. You wouldn't be surprised to learn she got beaten up because she accidentally made a mistake on Anna's homework again. She was sitting there, hugging her knees with all four arms, and hadn't noticed you yet.
