Chapter 1: Who's This?

~-~ Selecting Y/N TOMIOKA'S POV ~-~

It all started when I was Five. I was young, scared, weak, traumatized, and most importantly, I felt betrayed. I didn't know why he did it, I didn't want to believe that he did it. But that was the reason I became the person that I am today. 

Me, Tomioka, Y/n. The light Pillar in the Demon Slayer Corps. The youngest, yet one of the strongest Hashira of the Taisho Era. Couldn't have done it without that great, brutal, agonizing betrayal.

I've been training as a Demon Slayer since I was Five. That's the real reason I'm 'strong'. The first thing my master taught me, was body composure, having a bunch of Stamina, and having pretty strong muscles! I became a Hashira at the age of Twelve, right after Mitsuri! I've been a Hashira for at least a month now.

I've even developed feelings for the current Mist Hashira, Tokito Muichiro! He's so majestic! Have you seen his hair? OH, his beautiful hair-

"Ms Tomioka?"

"Parden? Oh yeah!" Anyway, I still remember that day, like that back of my hand. The Day, where I killed the Upper Rank Three Demon and Became a Hashira.

I saved The Flame Hashira, Rengoku Kyojuro. He saved me once before as well! We became good friends. Here let me tell you in a better way . . .

"GET AWAY FROM ME! I said I don't want to fight you!" A Basketball-looking demon screamed as he ran away from me, once again. Too bad I'm faster.

"What's the matter, Basketball head? Too scared to fight a girl?" I jumped up on a tree and landed Infront of him. I swung my sword and sliced off one of his arms.

'This has been going on for an hour now! This is madness! The Sun is about to rise as well! I need to stop this and get to lower rank 1 before master gets mad! But she scares me, never once in all my life have I met someone without that! Even a baby has a faint tint of it.' He thought.

He jumped off the mountain, landing somewhere I couldn't quite find a location for. He headed to a crash-landed train sight. Luckily for me, I have precise hearing. I jumped off the mountain as well, landing on my feet.

I had to run as fast as I could to that Demon and swing my blade at him before he's able to attack the Flame Hashira, which I haven't seen in around Five months now. "Light Breathing, First Form. Sunrise!" I leapt at him and quickly decapitated him before he could get into another fight.

"Ugh! Why you! I couldn't sense your fighting spirit, you didn't have one! That's why I got beheaded! It's no problem, I'll just kill you as well!"

"Luckily for us, your time is up. Go back to them. They're waiting for you." I told him nicely, my sword ready in my hands.

"W-What?"

"Go. Rest. They're waiting for you to go back." I repeat, showing a tint of sympathy. He slowly starts to remember his past, tears falling out of his eyes. He starts to desinagrate as I smile towards the shining sun. It took a while to hold that Demon back. I'm just glad that he didn't attack me seriously. Otherwise, I couldn't have killed him alone.

"Young Comrade! Is that you?" I hear Rengoku yell. With one of my hands covering my eyes, shielding them from the sun, I put my blade away. I turn to see Rengoku, with a proud and happy smile on his face. I ran up to him and jumped up to hug him.

"Well DONE young Comrade! Now, you can become a Hashira! I'm so proud!" He hugged me back. I've always seen Rengoku as a brother.

"Thank you, Rengoku. It means a lot!" He patted my back as he put me back on my feet. I turn to see these two Mizunoto's. One was wearing a boar mask, the other was on his knees. Staring at me with shock written all over his face. "Who's that?" I ask him.
