No one pov
The next day everyone was in class except for Nagisa.

Karma couldn't help but wonder what happened to her.
"Does anyone know where Nagisa is?" Korosensei asked as he was taking attendance
"..."
Everyone only looked at each other hoping someone would know.
"Tch" Karma snapped and just as he was about to stand up to go look for her the door opened to reveal Nagisa.
"N Nagisa?" Kayano called out
"What happened?" Rio finished
Karma could only stare in shock and confusion.

Nagisa was not wearing her school uniform. She was instead wearing jeans and a blue turtleneck.
"Nagisa, why aren't you wearing your uniform?" Korosensei asked
"It got dirty" she stated bluntly and walked to her seat

Everyone dismissed Nagisa's behavior, but Karma wasn't having it.
He knew Nagisa for 5 years and she never acted like this without a reason. He also knew she was a great liar.
He had to get to the bottom of this.

Throughout the day Karma kept a close watch at Nagisa, but everything was normal.
She took notes, wrote weak points on Korosensei, talk with her friends and eat lunch with Asano.

Karma sighed to himself and leaned on a tree during their assassination training.
All of this was pointless.
Was he just overreacting?
Maybe he should just ask her face to face.
He closed his eyes and drifted to sleep

"ma"
"Karma"
"Karma!"
He got up in a panic
"Karma?"
He turned around and saw Nagisa next to him
"What are you doing here?" He asked
"The bell rang. I was going to walk home with Asano, but I saw you here sleeping so I came to wake you up"
Karma looked down and blushed a little, glad that Nagisa still cared about him
"Nagisa!"
They both turned around and saw Asano a little far back, but could tell he was annoyed
"I I should get going"
She stood up and was about to walk away when Karma grabbed her wrist
"Wait!"
For a quick second he saw her clench her teeth as if she were in on pain
"N Nagisa?" He called her to make sure she was ok
"W What is it Karma"
"It's been a while since we hung out, maybe we can hang on Sunday"
She turned around
"I'd love to!" She smiled
"Nagisa" she heard Asano call her
"I I better go, bye" she waved and ran off to Asano

Karma looked at his hand
"Something is definitely wrong"
At first he thought Nagisa was going through a phase, but there's probably a bigger reason.
He looked up
"Nagisa, what are you hiding?"
