Sanctuary (Karma Akabane x OC)

The Assembly

"Hey Katsuna, want to be lab partners today?" Nagisa called, smiling as the girl nodded. 

The class had broken up into chatter as they waited for their lesson to start. 

"Okay, you ready boys?" Maehara exclaimed, thrusting his anti-sensei knife into the middle as Okajima and Mimura followed suit. 

"To killing Koro-sensei!" they cheered, their hands rising into the air. 

"He's coming," Sugino announced as he peered his head round the door. Koro-sensei was carrying the lab equipment along with Isogai and Kataoka, the two students distracting him with conversation as they drew nearer to the classroom. 

Maehara quickly hid behind the door frame, just in time for Koro-sensei to slither in. 

In a flash, the orange haired boy horizontally sliced the air, launching his knife towards his teacher. However, Koro-sensei disappeared, slipping past the boy using his mach 20 speed, leaving the boy in surprise. 

The two other boys ambushed their teacher, knives in hand as they attempted to corner him. Koro-sensei grinned, passing them with ease and began prepping for his lesson. The attacks kept coming, the boys running and missing their teacher by inches until they finally collapsed in the corner of the room in exhaustion. 

"He didn't just seriously dodge all of us whilst setting up lab, did he...?" Maehara gasped, worn out from the running. 

"Dammit, I thought this plan was going to work.." Okajima wailed. 

"It was wayyyy too obvious," Karma commented, snickering at the boys' failure, "He would have expected something like that from a mile away." 

"And yet I still don't see the octopus dead with your knife in him," Katsuna muttered, making the redhead turn in around and glare at her.  

"Now, now class," Koro-sensei lectured, grabbing the chalk with his tentacle before writing the learning objective, "Lesson's starting, so can everyone take their seats." 

The boys slumped into their designated seats in a huff, watching as their teacher turned to face his class. 

"Today we're extracting colouring from processed food!" 

"Great.." the class sighed. 

"And I'll be taking the leftovers if that's all good, yes? Great!!" he went on, his face beaming. 

"What are the chances that the only reason for this lesson is so he can feed his sugar addiction?" Katsuna whispered to Nagisa, a small bead of sweat dripping on her face. 

The boy chuckled lightly, "I'd say about 100%." 

Just then, Okuda stood up, alerting the class in interest as they wondered what she was going to do. Okuda was someone who doesn't usually speak up, so it was a surprise to watch her stand out from the crowd. 

The girl wandered to the front of the class, glancing at the ground nervously before speaking up.

"I-I," she stammered, unsure on how to get her words out, "P-poison Sir, can you consume it.. please?"

EH?

Koro-sensei was taken aback from the strange request, the rest of the students following suit. 

"Well she definitely likes the direct approach huh.." Nagisa stated, observing the girl in pity. 

"I'm not very good at being secretive and sneaky, but I worked really hard on these poisons," Okuda babbled, "So please could you try them?"
