Everyone has graduated Kunugigoaka Junior High School. Koro-Sensei death took a toll on everyone even Karma but they all learned to move on. But they still remember him dearly.
Now everyone has returned back to the school for a reunion with the small class. Cleaning and talking, catching up on each other lives, just hanging out with another. A few jokes here and there, laughing and smiling. Everyone was feeling happy!
A hour later
When everyone has finished cleaning and decided drink some water and eat some food, you felt a tap on your shoulder. When you looked up and saw Karma himself in his new haircut smiling down at you. "Well, well, well, if it isn't the little fashionista herself! You changed a lot! Well so did everyone else too but you've changed!" Karma said while laughing and smirking as well.
"It's nice to have the class back together though." Karma said looking up and around at everyone else who were talking to each other. "Nagisa is still shorter than me! Only grew one or two inches taller" he snickered. "Whatcha been up to lately? Dating anyone yet?~" Karma said looking back down at you. Then he took your water bottle outta your hand and drinked the water"
