What Happened? (PJSK)

How it started.

{SHIHO HINOMORI POV.}

Names Shiho, This is my story.

I lost track of how and when it began, but it had to be somewhere in winter. Shizuku and I were walking through town. We saw her friend Airi, she seemed to be off. "Airi! Nice seeing you out here! Is something wrong?" My sister approached her, Airi looked at her, and all I saw of Airi was.. Well, it's hard to explain. But Airi was damaged. Scars on her neck, face, and cheekbone.
It's odd how she looked unlike her usual, but back on topic.
As I ran, I knew that this Airi had attacked and started this apocalypse using my sister.
I was scared, afraid of who'd be next. Ichi, Saki, Honami? The thoughts of the chances were low.. But this world is more than we expect. And that's how it was when all this began. I heard screams of terror, pain, and so on. The screams were close, and with how I was, I hid behind a tree, hoping it'd be big enough to hide myself from what'd be there. I tried keeping my tone down, my heart skipping beats practically. As I heard a crack from nearby, I stood up and ran as fast as I could, never once looking back. My thoughts got ahead of me, though. I would be faced with my (now zombie-like) sister. She stared at me. All she mumbled was, "Shiii... You'll be with me.. Just come with me..". I knew it was my sister, and not some fake. I'd make her a bracelet a week before, and she was still wearing it. I stepped back, pulling out my guitar. She stared at me, slowly stepping forward. I could see my sister hidden within the darkened eyes this had. My eyes had begun tearing up as I raised my arms to bash her head in. Her eyes plead for freedom of this endless pain she'd gone through. I hit her with the guitar. The red pupils vanished, and my sister became normal, second before she had surrendered to death. I stood, my guitar now stained with my sisters blood. I dropped to my knees, cradling my sisters lifeless corpse as I sobbed. I begged for forgiveness, I begged for this to be a dream. I pinched myself, realizing this was indeed not a dream. I let go of the corpse, giving her one of my spare guitar picks for in case she woke. Which wasn't possible, considering how badly I'd beaten her with my guitar. I made a run for it, going house to house, neighborhood to neighborhood, alleyway, and alleyway. None of my friends showed. I couldn't find them. Then, I came across two decent friends of mine. Those two are Akito and Kohane. I muttered, "Hello." This caught them both by surprise. "Hinomori! Have you seen An?! I'm getting super worried she got involved with this mess.." Kohane said. She looked like she was on the verge of tears. And so was I. I mean, I just killed my sister, watched her die, and ran off. I was practically overflowing like a jar with too much water. "No, sorry.." I had mustered without tearing up. Unfortunately,  Akito noticed my emotion. "Yo, Hinomori, you good? You look off." He said. Getting up from leaning against the alleyway wall. Seconds after, I explained to him and Kohane what happened back in that forest. They listened carefully, not once interrupting me. Middle of my story, we heard something. "An? Could it be An?" Kohane mumbled. "Kohane, it couldn't be An. She doesn't sound like that, and she comes running, not slow walking.." Akito mumbled in response. And surprise, An popped out from the corner. She looked like Airi. Biten, scars, etc. I took my guitar, still soaked within my sisters blood. Raising it, "I'll do it again, zombo!" I yelled, An not listening. She came charging. I slashed her with the sharp edge of my guitar. She fell in response to the attack. Kohane, now realizing what An was and why she was acting so weird, She picked up a trash can with all her strength, bashing An's head in. Like I did with Shizuku.
