"You're just a little girl. Live to your true potential." The emotionless little girl who can't feel pain is left astray. She's pushed aside by her peers, left out of activities for being 'different'. She's still the same as you and I, just a little less...human...per say. But all the other students view her as a shell, a waste of space, someone who is stealing their precious air. Just a waste. But when in boy comes along, he can give her emotions. But this gets taken too far, and everything spirals downhill. The shell of a human, can feel again. The waste of space, isn't emotionless. The nuisance has a purpose. But this isn't a good thing. She's not a little girl. She's a Yandere.

Ayano Aishi always held a simply undeniable love for Taro Yamada. She and ten other girls at Akademi High could not imagine their lives without him. She made it her life mission to take those girls out. Senpai was hers, and she'd make sure of it. She would stop at nothing to make sure she had her Senpai, she would go to any length, until blood was running down her hands and they were gone from the world forever. Just like her mother did. Until one day, Ayano Aishi's feelings vanish. Something she could never dream of happening, something so unfathomable that it hits her like a bus when she notices. Because her heart now belongs to someone else. How unlikely.
