Celest POV
Walking into the classroom with my supposed family and going straight for my seat at the opposite end of the classroom to the others. I still distance myself but I treat them like closer friends than I have anyone before due to my lack of previous social experience and family. After a while of listening to Korosensei and taking notes, he decides to take a nap leaving us to our on devices on a task. I look around to see what everyone else is doing so before I noticed the blue haired kid walk up to the front of the class. Noticing the knife behind the clipboard I knew what he was planning to do. A quick swipe of the knife and a fast dodge in response is all we saw before an explosion of bullets ricochetin everywhere! Everyone was ducking for cover, friends with friends for comfort. I edge towards my companions and notice Sakura in the corner with Aoi and Mukuro.
Sakura looked almost nothing like her usual self, it was clear the attempt on Korosensei's life had affected her a lot worse than expected, presumably because of how the androgynous boy had gone about it. Her face was flooded with tears and her breathing was rushed. Her large frame was shaking uncontrollably and on either side of her were Aoi and Mukuro attempting to calm the giant down to a state where she could tell us how to help her. "How many fingers am I holding up?" Mukuro asked holding up four fingers. "Four" came the reply, Mukuro changed the number of fingers on her hand "two" she changed again this time including her other hand requiring Sakura to add the two together "seven".
Mukuro pointed to Aoi, "who is this?" she asked "Asahina" came the reply, "What can you tell me about her?" she asked to keep the panicking girl distracted until her breathing was under control. "She love's doughnuts, she's the Super HighSchool Level Swimmer, her birthday is April 24th, she has blue eyes and her brother is called Yuta" Sakura was much calmer now as she spoke "She like's piggy backs and riding on my shoulders too and she can never stop fidgeting" she finished poking Aoi in the ribs.
Satisfied that the situation was resolved I turned to the rest of the class who had confusion of various extents written all over their faces. I turned my face back to the corner of the room "Is it because of when she..." I trailed off because however extensive my vocabulary may be there is no way to ask that sort of question politely. Mukuro nods her head in affirmative. "Before one of you asks in what would no doubt have been a completely insensitive fashion I shall give a small explanation." I assure. "Before we arrived at this school we were involved in an event which I will not disclose for the comfort of my friends. This event led to the deaths of eight of our friends. During this event Sakura attempted to take her own life for reasons that I will not disclose. Furthermore anyone who says anything unfavourable about her or this event will find themselves in an uncomfortable situation." I intoned, smiling.
Mukuro POV *Flashback*
Smiling slightly I stood up helping up Sakura and Aoi, turning round to see everyone staring at us my smile faded. When she'd attempted to take her life it had been different and a lot harder to calm her down.
I'd spotted Sakura holding a bottle from the Chemistry lab but it was clear that it wasn't protein. Immediately I tried to open the door, when it failed I quickly broke the window and climbed straight through. I sprinted towards Sakura and grabbed the bottle, a quick check revealed it was half empty. I threw the bottle into the corner of the room breaking it and rendering it unusable. Sakura was clearly startled and disoriented, I sat her down and stuck my fingers down her throat to trigger her gag reflex. Footsteps came echoing fast pace down the corridor and Aoi looked in through the window. I ran quickly over to the door and moved the chair out from underneath the handle to let her in.
Sakura was barely conscious on the sofa. Aoi's eyes were fixed on her as her legs gave way "Will Sakura be okay? Please say she'll be okay, what do I need to do?" asked the frantic girl. "Talk to her, make sure she stays conscious I'll go and get help." I instructed, Aoi made her way over to the sofa and started talking to Sakura about random things, Sakura watched her disjointedly with a pained and regretful look in her eyes. After that I'd ran until I found Mondo with Chihiro and got them to follow me with Chihiro lagging behind a bit. After that we'd gotten Sakura to the infirmary. From there things had progressed slowly with Sakura recovering and explaining why she'd tried to poison herself.
Nagisa POV
When I had tried to kill Korosensei with the grenade he had been angry about my lack of caution but that hadn't been the worst thing that happened. The worst thing had to be when we realised what was going on in the back corner of the class. Seeing such a strong individual seem so broken shook the entire class. It was a huge reality check for us and it really made it dawn on us how much our actions could affect others.
As the end of the day arrived I left my desk and walked out of the classroom. I saw Sugino heading down the mountain. I caught up to him. "Hey Sugino!" I called out to him. He stopped, turned around and waited for me to catch up. It was clear we were both trying to act casual but we were both failing horribly. The mood for the rest of the day had turned to shock and guilt for everyone. We don't know what happened to the transfers before they joined but today made us realise it must have been horrible for them.
"So uhh" he starts. But he doesn't finish. We end up walking down the hill in silence. Mutually understanding that no words can fix today.
