Assassination Classroom Oneshots

Reader as Nagisa's mother(?)

"Mom! I'm going to school!" Your son yelled, and you quickly rushed to him in order to give him a hug." Have a good day, sweetheart." You let him go, and brushed his light blue hair out of his eyes.

He walked out the door, as you got a phone call. "Hello?" You said, recognizing the number as your boss. "Y/N, we need you to help with the assassination of Ryushi Korogane, also known as The Reaper." It was Karasuma.

"Yes, sir." You hung up, and sighed. You knew the location already, and slowly headed towards the old building. As soon as you got there, you crept up to the door, and quickly opened it and swung a rubber knife. 

"AHH! HE'S TOO FAST!" You screamed in distress, crossing your arms and pouting, sticking your lower lip out. "MOM!?" You fell off the desk, and slowly stood up, only to see you son standing up too. 

"THAT'S YOUR MOTHER!?" The class shouted, and you sighed. Not only did you look a lot like your son, but you did have the same feminine appearance. After you got done explaining, everything made sense to the class, but you saw your son furrow is brow at you. 

You smiled, and your phone buzzed. "I have to go." You said, taking off your original outfit, revealing a business suit. You walked over To Nagisa, and kissed his forehead, and ruffling his hair. You heard the class talk about how much you looked like their friend. 

After you walked out of the building, you where met with the principle. "Why hello Y/N, I see you haven't changed one bit. You still look young." You laughed, and thanked him. "Do you mind giving me a ride? I can't jump from roof to roof in this." 

Gakuho led you to his car, and He held the door open for you. You waved to a strawberry blonde boy in the backseat, who waved back confused. "Is...This a new student perhaps?" The boy asked, very flustered for a moment. 

You chuckled. "I'm flattered sweetie, but I'm 40." You smiled, smirking slightly. "Oh where are my manners, I'm Y/N Shiota. I'm an old friend of your father's." 

"How did you now he was my son?" Gakuho asked, while you looked at him like he was an idiot. "He has your eyes. He also looks like you, but you have darker hair, your also graying." You said, poking the side of his head, where gray hairs where shown.

"Yeah, keep rolling your eyes, maybe you'll find a brain back there." You said, crossing your arms. "I HAVE A BRAIN!" Gakuho exclaimed, wanting to strangle you. You pursed your lips, blinking at him with your arms still crossed. 

"Your brain is the size of an amoeba compared to mine." You said, opening the car door, and waving goodbye to the boy in the backseat. "Gakuho, Gakuho, Gakuho." You said, clicking your tongue as you where met with your husband.

"Oh hello Darling, how was your day?" He asked, opening his arms. You gladly entered them, sighing. "I ran into Gakuho and his son today. I think I roasted hi pretty well. I also met Nagisa's classmates." You said, closing your eyes.
