You were walking in the woods at night and was a female.Akaza seen you and straight up ran to you ready to kill you."Are you ready to die mortal?".He didn't fully see you at first since it was night he was walking up to you."I will kill y-"...Something made him change his mind he realized you were a female.

He wouldn't harm a female but you were a demon slayer and was trying to fight him.Akaza knew he was stronger then you but he turned and walked away.He wouldn't allow himself to harm women...
