You were a hashira the moon hashira to be exact no one really knew your backstory except Giyuu because well you two got along the best you were covered almost head to toe in scars you used duel Katanas so they were always hoisted on your back. Right now everyone was with Tamayo Kagaya thought it would be good to get to know each other's backstories of course no one disagreed so they used Tamayo's blood demon art everyone else had gone so you went last when you did the illusions from Tamayo's blood demon art changed to a younger you about ten a voice spoke from the illusions like it did for everyone else but only you recognized the voice.

???: "All of this beauty that surrounds us every lovely bloom designed to defend."

The illusions changed to a 15 year old you covered in blood your own blood kneeling beside a body of the person who's voice spoke your old mentor was who the voice belonged too the voice spoke again but weaker.

???: "Let them come just let try don't be afraid to say goodbye."

The voice died out as your old mentor died as well the illusions stopped as everyone looked at you in shock you had gone through this at a young age!? Giyuu was the only one not looking shocked as you had told him all about your past.
