Here's a pic of Ayano before and after she killed people for her Senpai. I had to use different pics to turn it into one pic that's why it's so different.

Ayano's POV
I was walking by Musume and her gang when I heard her say something that got my blood boiling so I hid behind a tree and spied.  "Hey girls! Let's bully Taro! He's always sitting on the fountain reading that lame book ALL. THE. TIME! So let's be rude to him!" The other four giggled and nodded. I growled and when Musume was alone I snuck up to her and STABBED HER TO DEATH! "That should teach you, pathetic bully" I growled and left.
