*you recently joined the demon slayer corps. After years of training alone you passed the final selection aside Tanjiro and the others. You were only 13 at the time bit you didn't really care and it didn't matter. You recently got sent tl the butterfly estate after a mission where you got attacked by upper moon. Of course you weren't ready for something like that yet. You were in your bed after your rehabilitation training with and Kanao. You weren't talking to anyone there, you just stayed quiet and you didn't show any emotions either.

it was your day 5 at the butterfly estate. You were walking to your room after another rehabilitation training session when you passed by a room that's door was slightly open. You could hear someone eating and saying loudly

???:" Tasty! Tasty! Tasty!"

you peeked in to see a man with yellow and red eyes and yelloe hair with red tips. Eating sweet potatos. He noticed you

???" Ah! Hello! I didn't notice you there! Do you want to join me?" he asked brightly with a huge smile. You hated talking bur you were alone anyway so without a word you sat next to him

Rengoku:"My name is Rengoku Kyojuro! The flame hashira! Who may you be? I haven't seen you here before!"
