It's been months since the last time you saw you older brother, Obanai and a lot of things changed since then.

When he found out you became a Demon Slayer he instantly wanted to talk to you and tell you how dangerous it is.

Quit! He said with crossed arms standing in front of you. He had told you multiple times not to be a Demon Slayer, tho he was secretly very proud of you but he would never admit that.
