You had become a demon slayer for a reason none quite knew. Obanai Iguro noticed you on a mission. He thought nothing more of you at the time, just another low ranking demon slayer in the face of a Hashira, yet he couldn't find anything that could take his mind off you. It wasn't difficult to get you to accept his training and with you as his protoge, he only wants more. It wasn't enough just being your mentor and living with you though, he needed you.
