It all started with a disagreement. Nagisa wanted to find some way to save your teacher, whom was a ticking time bomb. With less than a month to assassinate him, you felt anxious and had been working your ass off in the background whilst appearing to be the violent, arrogrant-yet-genius-prick of Class E, otherwise known as the End Class.
You taunted Nagisa by pushing him back and forth, you couldn't help but feel your blood boiling. Why did he want to save a lost cause? Why did he want to save a supernatural being, whom planned on self destructing along with the Earth itself?
Due to your strength, even Isogai and Maehara struggled to stop you when you decided to attempt a triangular choke on Nagisa. While Sugino held Nagisa back.. Who looked childish as he swung his hands up and down. Koro-Sensei settled it with a paintball fight, Red for people whom want to assassinate their teacher, and Blue for people who don't want to.
You planned this all out perfectly, even using some of your teammates as bait whilst you stayed close to your flag. Mimura was recently eliminated, so you didn't have a walking CCTV camera. Nakamura and Terasaka's squad came back, holding the blue flag. A smug smirk crept up upon your face, victory was well served on your plate today.. Or so you thought. Nagisa suddenly appeared out of nowhere, slashing the four with his rubber knife, tinted with blue ink. Your eyes widened out of irritation and surprise, this wasn't fair.
Maehara thought you had let your guard down, lunging at you from behind. "Got you." He mumbled to himself, his blue ink missed you by a centimeter and you ended up shooting him with your gun, loaded with BB bullets dipped in red ink, as it hit him on his chest. Your senses were far more superior.
But how come you didn't notice Nagisa? It was between you and him now, but you couldn't help but feel a source of joy. There was always this mysterious aura lingering around Nagisa, it made you feel uneasy.
Now, you can unfold all of his secrets.
