Flames for the demon (sengoku strays fan-fiction)

"You can do it Nee-san!" went two young voices from the spectators seats. I chuckled and nudged m best friend and general, Kasane Kusanagi. 

"It seems the terrible two are calling for their big sis." I teased, grinning slightly as she waved up to the twins, Masamune and Kotetsu, blonde with big blue eyes that make even the captain melt. I grabbed the back of her robe. "It's your turn baka." I turned away and waved a hand. "Knock 'em dead kiddo." I joked and sure enough she easily defeated her opponent in a matter of four moves. Me? Who am I? i am called Sakuraoni kagamehoshi, in full translation it means cherry blossom demon of the mirror of stars, hense my nick name 'the oni queen' when I step on thekendo mat my aura turns demonic. Eheh, i'm really the happy go lucky kind of girl really, my family teaches the sword of amaterasu, the mother god, I'm considered the prodigy; ah, not that I want to brag though! 

So where was I? ahhh yes I remember! The matches, I won with two moves, I was feeling gracious today.

"Sakuonii-chan!" the twins called over to me and i went over and put my hands on their heads. "You were amazing!" i chuckled and scratched my chin. 

"Eheh, really?" Kasane joined in with their rather ferocous nodding. I just dead panned at them.

"Are you gonna have dinner with us tonight Sakuonii-can?" kotetsu asked me and I couldnt look at the puppy eyes all three were giving me. i groaned and nodded.

On the way back Kasane and Masamune were discussing family and I was telling my mother that I would be staying the night at Kasane's, when I heard a screech.

I dropped my phone and ran full pelt at a frozen Kotetsu, who was standing in front of an oncoming van hold a strange sword. Both Kasane and I had grabbed him and the next thing I knew there was a huge flash of blinding light.

I opened my eyes to wide open skies, grassy plain and a few touches of trees.

"uuurmmmmm........" came a groan of a very familiar voice, "Earthquake!" she yelled just as a group of horsemounted soldiers galloped past us. "Sakuraoni!" Kasane yelled as she saw me sitting near, stunned at what I saw. she turned to see what I was staring at and saw a full view of fields, no tall city buildings, no tractors or cars. "W-where are we?" I heard her whisper.

"Well well what do we have here?" came a voice from behind us. Both Kasane and I turned sharply and were greeted with the sight of some rather worn and torn soldiers leering at us, the weapons raised. "Two women from the village." I pushed kasane behind me.

"Stay behind me kasane." she nodded. "When I say run you run full pelt to the trees, ya hear me?" i whispered to behind me. raised my hands, ready to defend the two of us.
