Here is my contribution for the Karmanami week! I couldn't participate sooner because of my finals during the whole week, so I'm going to start straight at day 6. This takes place about 4-5 years after the end of the manga. Sorry for all inconsistencies in characters or concepts, OOC's or linguistic mistakes.

Disclaimer: If I did own Assasination Classroom, Karmanami would be clearly canon at the end of chapter 180.

Karmanami Week, Day 6: Koro-sensei

I-I'm not good at surprise attacks like everyone else… but chemistry is my strong point so I put my all into making these!

It was difficult for the former God of Death to not think about the first and only woman who made him feel the happiness to have someone really looking at you when he saw the raven braided-hair girl presenting the three tubes of chemical potions at him. Even though Okuda Manami could be easily missed at first among the other students of class 3-E because of her quiet and reserved nature, the yellow octopus acting-teacher took note of her right away ever since he did the first roll call for his class. Aguri has always mentioned about her students a lot during his time with her at the research lab after all, and Okuda was a frequent name that usually came out during their discussions.

As Aguri herself specialized in chemistry, she couldn't help but direct a bit more of her attention towards the shy student with a propelling talent in the same field. She did share quite a few stories with the former God of Death about staying back after school and guiding her favorite student to perfect her prowess in chemistry. She even admitted, a bit guiltily, that she did break the school rules a few times by allowing Okuda to extract poisons from plants in the school lab, but quickly added that she was always there to supervise her student every time. It was safe to say that Okuda was the student of class 3-E that she was able to talk with the most, and the only one that she managed to help gaining some slight self-confidence during the process. The female rookie teacher was always pleased to see the radiant smile and shine in the petite girl's eyes each time she talked about chemistry, and Aguri did her best to encourage her to keep improving her chemistry skills and to never give up despite the situation with class 3-E.

"What are you looking at, Koro-san?" spoke the very subject of his musings, bringing him back to the present from the reminiscing lane.

The obsidian-haired man turned around and smiled fondly at the approaching black-haired woman in a white lab coat and a t-shirt underneath with some strange patterns on it.

"I was looking at some photo albums of the first and only class that I've ever taught, and thinking about you." casually said Koro-sensei with a smirk.

"Wha-? Please don't tease me. Why would you think about me when we see each other every day here in the afterw-" Aguri stopped herself when she spotted the specific photo that the man was looking at, featuring a raven-haired bespectacled girl presenting her yellow octopus teacher the tubes of poisons.

"Ah, this is the time that Manami-chan did her first assassination attempt at you right? What a straight-forward and honest girl! I always knew that she would be able to pull off extracting those last three types of poisons that I taught her to." smiled fondly Aguri at the memory of her times when she was still alive together at the school lab with Manami.

"I know. She reminded me of you in a lot of ways: from her forte in chemistry, her weakness in Japanese to her honest innocence." chuckled amusedly the suave man at his beloved companion.

"Hey! Manami and I weren't that bad in Japanese! –protested Aguri with a cute pout, and you did say that she managed to get much better in it afterwards, especially thanks to Karma-kun right?"

"Yeah! The little devil was quite clever to offer his help for her to improve her weaker subjects in the sole objective of spending more times with her after school, with Manami-chan innocently agreeing to it without suspecting anything." said Koro-sensei with a small hint of mischief.

"You know, Karma-kun and you do share quite a few points in common too. You are both smart, good at reading people, but took time to fully trust them and can be quite mischievous when you want to. You had no qualms in approving his mischief sometimes when you and him both shared the same goals right? Not to mention that you were the one who set them up together in many occasions!" exclaimed Yukimura-sensei with a teasing smile.

"Yeah, they're one of my favorite couples alongside your sister and Nagisa-kun! But even my perfect schemes wouldn't get them together if they themselves weren't interested in each other in the first place. Both Karma-kun and Manami-chan have proven to care a lot about the other many times during the one year that I was with them."

As if to prove his point, the former God of Death showed his Karmanami photo collections that followed suit in the same album. The one that showed Karma and Manami respectively as the knight and the witch in the play for the children at Wakaba Nursery School, the one where Manami was treating Karma's wounds after his final fight with Nagisa in the Class 3-E's civil war and the one where Karma held Manami's wrist and shielding her from Shiro's mad erratic attacks at all the students, were only a few examples among many, many other photos in the collection. Aguri couldn't really decide whether to scold her beloved companion for his intrusion in their students' privacy or to be amazed at his commitment to be present at all those moments and capture their special instants together. She settled to smile sweetly at him and said in an excited voice:

"Well seeing all these photos of them together made me even more impatient to see their wedding next week! We would get the front row seat to watch their special day thanks to their decision to hold it at the old 3-E campus site."

"Of course! We definitely wouldn't want to miss it right?"

So it kinda turned out to be a Karmanami ft. Koro-sensei and Yukimura-sensei in the end… This idea came to me when I reread the Ansatsu chapters recently and discovered that Yukimura did really specialize in chemistry and that she specifically mentioned Manami's name to Koro-sensei when she was talking about her class 3-E's students. I picked the song at the beginning of the chapter because I think that its melody and lyrics do match this chapter to some extent =D Hope you enjoyed it!

I'll try to post the next and last chapter for the Karmanami week prompts tomorrow or latest by next Monday hopefully, since I still have a report to write during this weekend.
