I jumped through the trees at top speed, avoiding encounters with any enemies in an attempt to reach my brother as soon as possible. My black and (f/c) coat swaying behind me as I ran and jumped, (e/c) eyes focused straight ahead and ears listening put for any abnormal noises. So far, I've not had to acknowledge any enemies so far as I've not been noticed yet, but I still have one more person to sneak past, and he'd the leader.
I soon felt a string kick come to my back, pushing me out of the trees. I looked up and saw the man from before holding a gun and smirking at me. I guess I'll have to fight him, then. How tiresome.
"You do know, you can save us both the fight and just let me through." I mocked, pulling out my two katanas that were strapped to my belt. His smirk only grew as he walked towards me, taking off his glasses and getting in a battle stance. Fighting it is, then...
After a while of us staring at each other and analysing each other's moves, I ran towards him, watching him swing. I quickly jumped in the air and tried to kick the side of his head, but he grabbed my leg with his arm, throwing me into a tree. He's going to be tough. He seems to have caught on to my fighting style rather quickly, so I'll need to randomise my moves a bit to confuse him before a strike him down and run for it.
He charges at me and I wait until the last second before going to the side and pulling out a throwing knife, effectively cutting his side. This is my chance. I run up behind him and strike a certain spot on his back with great force using the hilt of my blade, effectively paralysing him.
I carry on with my journey and soon reach the wall of light where my brother is held. I see him emerge from the building and stare at me.
"Brother..." I breathe out before sprinting over to him and giving him a hug.
"So I guess this is it. Huh, (y/n). Where are the rest of your classmates?"
"They're probably coming soon. I just came here on my own, but they shouldn't need my help getting past these defenses." he just nodded in reply.

Time skip to when the rest of the class gets here~

I stood next to my brother with a massive smile on my face. Everyone was here, we were all ready to spend big brother's final moments with him, and I've decided that they're going to be my final moments, too. I won't tell anyone until the very end, of course. Me and big brother going together... That's how it should be. Everyone ran up to me and him, hugging him and smiling.
But our joy was cut short by two beings walking through the wall of light, one was cloaked on black, and the other was cloaked completely in white.
"Happy birthday, Koro-sensei. The time has come... I shall gift you the world's cruelest death." I watched in horror as the man in all black unzipped his clothing, revealing nothing but a monster underneath. Before I could comprehend what was happening, the monster attacked big brother, clearly winning by far.
"Shiro! COME AND FIGHT ME YOU PATHETIC BASTARD!!! YOU MAKE EVERYONE ELSE DO YOUR WORK WHILE YOU WATCH FROM THE SIDELINES, BUT NOT ANYMORE!!!" I screamed at him, anger pumping in my veins. He smirked at me, pulling out a syringe and injecting something in himself that made veins appear all over his body.
"And what will a weak little girl like you do against this?!" I calmly walked into the class E building, going into the classroom and pulling up one of the floorboards. I didn't want it to cone to this, but it might have to. I placed the large weapon on my back and walked back outside.
I pulled my hood up, covered my mouth with my scarf and pulled out my katanas. My arms rested at my sides as I stood there, watching the man. He eventually charged at me, trying to hit me but I jumped up at the last second, kicking him in the head and chopping off his left arm. It began to regenerate quickly, so I quickly chopped off the right. Then, the true fight began. I put the swords back in their sheaths, grabbing throwing knife after throwing knife from my jacket. Some would hit him in the chest, some in the arms, some in the legs. By the end, he had collapsed on the ground, blood surrounding his limp body. I sauntered up to him, ripping out my knives.
"Tch. Who would've known such a weak little girl could take down such a supposedly strong enemy." I mocked, spitting on his body and turning around to walk off. I felt him grab my ankle and throw me away, my body colliding with the ground painfully, making me cough up some blood. I pulled out my katanas, sprinting towards him and giving him attack after attack. He blocked every single one, only getting a few cuts on his arms and constantly pushing me back.

Karma's p.o.v~

I had never been more worried in my life. She was taking quite a lot of hits, and I don't know how much longer she can take. She kept slashing at his arms, making him weaker and weaker, but he kept getting some hits to her stomach.
Suddenly, she sprinted towards him and jumped up, digging both of her swords into his shoulders and pulling him over her before slamming him down on the ground. How the hell did I fight against her and live?! From then on, she had the upperhand in the fight, constantly pushing him further back and getting more cuts on him.
Then, he struck a powerful hit on her stomach, sending her back. She just laid on the ground where he had pushed her to, unable to move. He picked her up and held her in place as she started to struggle.
"Hmmm, maybe I should make you my next test subject. Then the whole family would've become monsters!" With that, he pulled out another syringe and injected it into her neck before throwing her to the ground. I just stood there; frozen. She started screaming in agony and gripping her head as large lumps began to move around in her back. Something was inside of her and it was trying to force itself out. Her screams intensified as two massive pitch black wings ripped out of her back, blood spraying everywhere. "What is an angel without her wings, angel if death?!" She suddenly stopped screaming and let go of her head, just sitting there completely still. Then, her wings began to flap, making her fly up into the air. Her body remained completely limp until her head snapped in the direction of Shiro, her facial features finally visible; her (e/c) eyes were wide, her mouth spread out into a massive Cheshire grin and her wings were starting to develop (f/c) spots. (f/c) shards then shot from the spots on her wings, cutting Shiro all over. She quickly flew down, kicking Shiro in the chest and grabbing him by the collar before dragging him into the sky. She threw him up and hit him with her wings, repeating the action multiple times until she let him fall to the ground.
"Heh. My whole body is burning, maybe I should take Kayano's advice..." her wings set aflame, making a ring of fire around the two. Soon, her whole body was set aflame and enshrouded by shadows. She dragged him up into the air once more, stabbing him repeatedly with her wings before kicking him up further. A large, black and (f/c) scythe formed in her hands as she flew up to Shiro, using it to cut him in half and finish him for good. She kicked him away towards the wall of light, making his body vaporize.
She flew down to the ground, clearly exhausted. She was about 10 feet above ground level when she fainted, her wings going back into her back and the flames retreating from her body. She was practically naked, burns covering random parts of her body along with multiple cuts, bruises and scars. I sprinted up to her and took off my overshirt, covering her limp body before I took her back to the rest of the class. I sat down, staring at her before kissing her cheek. I nuzzled my head into the crook of her neck.
Please be okay...
