(This is inspired of a gacha react btw-)

you were originally training until you were teleported to a room, you were confused and was about to draw your sword, until you realized you didn't have it, and a voice, from a box spoke...

"Heya [name], sorry for the sudden disruption, but I was bored, so I'm having you and the hashira react to your past. A wonder you aren't dead by now,you may ask why I choose to do this. But this is so everyone can have a neutral understanding of you*

you wanted to ask questions, but you couldn't speak before you were teleported by one of the walls and...the hashira were teleported together in the room, sat just like you were, the first few minutes were yelling or questioning, but it settled down

and before a black box on the wall turned on, gyomei had some odd green glasses, which allowed him to see [somehow???[

*but the reaction started, the "creator" never specifically verified they were reacting to your past, and all 10 of yall saw some nice edits of a kid...[they never knew it was you yet]. And now the trauma

but it showed your dad and your mom, after a large scolding session at your...sister, [sense she was a bully, and wanted everything to be her way], it then displayed the next day after,..a horror filled scene, both your parents were unmoving on the ground...with your sister holding a knife...you remembered that she blamed their death on a demon and even framed you to be the one who lead them their, you were furious, you remembered the looks of disgust, and you hated it, you hated being such a weak ass kid..and it displayed much of your life having to do risky things to help people, sense at the time back then you were often used as a distraction for demons, and grew to be somewhat into this...though doesn't make it less horrifying...
