This mission was so stupid. Obanai hated being around people. So, when he was assigned to protect and watch over you, he was not happy. You were apparently being hunted by demons, and your father had enlisted the help of the Demon Slayer Corps to keep you safe.

Obanai sat outside your door, a small huff leaving his lips. He hated this. It made him feel useless. He should be out there, fighting upper moons and searching for Muzan. But here he was, babysitting you. Speaking of you, he hadn't heard you move in a while. The hashira stood up and knocked on your door.

"Open the door."
