You were a Hashira. A very friendly one.. but that wasn't exactly what you were known for. It was your extreme social phobia. It was so bad to the point that you couldn't even talk without getting nervous. So, you didn't. Sure, you tried, but the only sounds that came out were 'mph..' and various other tremble like noises.

You stood in front of Tanjiro as he tried to speak to you. "..." He didn't seem to know. Until Kyojuro Rengoku, the Flame Hashira, told him about your social phobia. "Oh!" Tanjiro looked at you again, his smile becoming wider. "Would you like help?" He asked you sweetly. "I could help you overcome your fear of being social if you would like!" He continued happily. He stood in front of you, looking up at you with pleading eyes. He really was a sweet kid.. he just wanted to help you overcome your fears. How sweet. You almost felt like crying because of how sweet he was to someone like you.
