Interesting! I especially liked the Karma & Nagisa interactions!

...

Awesome!

NOOOO it cant end there! This is too fucking good! I love nagisa assassin Au's and this kne us sooo perfect. Gah. Well, i loved id. Good job :)

This is defintely an interesting take on Nagisa
Have you considered turning this into a multi-chaptered story? How different the manga would be with this kind of Nagisa? (Of course I like to think that Tako-Sensei is a lot more adaptable in this ending)

Aaaaah~ can't get enough of Assassin!Nagisa *_* and Karma noticing Nagisa is also really cool :)

Dam... Amazing!~

Whoa.
That is kinda awesome.
Actually that isn't kinda it is REALLY awesome.
I love this AU idea. I love this Nagisa. But this story needs one more chapter. I'm thinking one chapter of how everyone reacts. Like karasuma who has been trying to kill him with his comrades and failed so many times just to see a kid do it, or karma who didn't know his friend was a killer, or Kayano (real name Akari Yukimura) since she did want to kill koro sensei after he killed her sister, after all, and Nagisa killed him for her, or just random kids in the classroom it is there first time seeing an assassination after all.
One more chappie would be awesome please do it.

I love it! Please write more!

Awesome.

Please make more updates. It's really good
