On this episode, Nagisa fights against the crazy Akira. Later, some shocking moments showed up.
So the finale was actually cool. It was nice to see Nagisa use his assassination experience against the Akira. Also the assassins who worked for Akira revealed their true intentions which was quite surprising. Other than that, I kinda hoped Koro-sensei would be finally assassinated but they left it open for a possible second season. Now will there even a be a second season coming soon? If so, I guess I'll be looking forward to it. Overall, cool intense action finale.
Conclusion: Cool intense action finale.
