The Devil Duo (Karma x Reader)

Part 31 (Graduation time)

"Korosensei? Kayano-san... she's" Nagisa said sadly as he held the limp green-haired girl in his arms.

"K-Kaede-chan..." Kurahashi sobbed out as an overwhelming sadness swiped every student and teacher there.

Karma gently put Y/n down holding her in a strong hug, making sure that the grieving and the shell-shocked girl couldn't see her friend.

"Let's lay her down," Chiba said as Korosensei immediately cut him off.

"No, don't, Nagisa. I don't want her to have too much contact with the germs in the soil." He said before he turned towards his students.

"Everyone, the past you've lost will never come back. I myself have made so many mistakes... but we can learn from the past, so we don't repeat it." He said as Karma loosened the hug around his girlfriend.

Silk-like glowing strings gently flowed out from Korosensei, holding a red ball in them.

"Wh-what is that?" Nagisa asked.

"Kayano-san's blood and somatic cells. I gathered them before she fell to the ground and stored them in a sterile cell membrane I made with compressed air." Korosensei said as they all looked at him shocked.

"In... In the middle of the battle!?" Bf/n asked.

"I'd set aside the tentacles meant for protecting you. Those were the only ones I didn't use for fighting. Now, to string all these cells together, one by one... Faster, more accurately... I've been improving my skills all year long."

"So if the same thing happens again, it won't have the same tragic ending," Korosensei said gently, while his permanent smile softened.

"Some cells, can't be replaced, so I'll leave gaps and fill them with my mucus. Within a few days, her cells should regenerate and replace them."

"I'm a tad low on blood. Type AB donors, please!" He said as Itona and Karma stepped forward holding their none dominant arm outstretched as Korosensei used his tentacles to gather some blood from them.

However, before Karma stepped forward, he handed Y/n over to Bf/n. They two exchanged a few words before Bf/n nodded in understanding, hugging her best friend tight.

"Nakamura-san! Gather up that birthday cake and put it in my mouth!" Korosensei said the blonde's eyes widened like saucers.

"Whaaat!? But it's a smashed-up pile of dirt-covered garbage!" Rio immediately responded not believing what her teacher was telling her.

"I need to replenish my energy! And I wanted to eat it the whole fight! I call 30-minute rule!" He said as almost everyone's expressions turned almost comically wide.

"30-seconds!?" They all shouted in disbelief.

"Delish, delish, delish!" Korosensei said as he shoved piece by piece of the broken cake in his mouth. Not long after, he was done with the job.

"Now, once her heart starts working, she'll come back to life. It should go perfectly according to my What to Do for a Gut-shot student... By: Korosensei manual." He said almost proudly as he held up his self-written book.

"Who'd even anticipate such a disaster!?" His students shouted out in disbelief.

"I can say this now, but of your bodies were ever torn to pieces, I was prepared to put them back together. As long as I'm around, that is." He said and smiled gently at them, before saying the last sentence.

"As long as the teacher is... properly seeing his student."
