You remember the day clearly...it was night, your family was asleep. You were awake in bed, not being able to fall asleep. You felt like something was wrong, something wasn't right...something bad was going to happen. It felt like a nightmare from there. The screams and blood in that house was terrifying.
Then your saving grace came...a demon slayer. He was strong and beautiful. While he was taking you to the nearby clinic, feeling like he should do that, you found out his name was Giyuu Tomioka...the water pillar. You didn't totally understand what that meant but you were thankful for him. He saved your life.
You never saw him after that. You quickly followed in his footsteps, becoming a demon slayer yourself. You wanted to be like him. Someone that protects people and kills demons, so no one has to go what you went through.
You were on a mission at a mountain. You didn't know the danger was in there before it was too late. Lowermoon 3 lurked on this mountain. You fought as best you could, but it was hard. That's when you see that familiar haori go by. The same figure and everything...it was him...Giyuu. He quickly slays lowermoon 3 like it was nothing. He mumbles quietly and emotionlessly with his back facing you.
"Good job on holding up till I got here." He sheaths his katana as he says this.
