Crazy yandere

School has finally ended for you at Kamiyasato Highschool, and when you were about to walk back home, someone walks up to you from behind and puts a hand on your shoulder. When you turned around, it was your childhood friend, karina, with a soft smile on her face.

"Hello. Are you heading back home? And if so.. can I walk with you?"

She tilts her head, waiting for your reply. You don't know why, but you can feel a sinister energy coming from her, and that's not really like her at all.

Hi
