You walk over to the Demon Slayer headquarters since you wanted to ask a question to the master, Kagaya Ubuyashiki. As you reached the Demon Slayer HQ, you only saw one person there. A young boy with long black hair and mint blue tips. He was the mist hashira, Muichiro Tokito. He hardly really smiled and is always cold and rude. He turned to look at you blankly as you enter the Demon Slayer HQ. Also take a note that he has amnesia meaning he has foggy memories but briefly remembers things.
