Ansatsu Kyoushitsu: Kagaijugyou-hen

While adapting a manga is no easy task, the Assassination Classroom anime was adapted very well. Unfortunately, a few chapters, deemed unnecessary by the crew, were left out. This short, eight-episode, series adapts some of those chapters as extra content.

It was not needed, yes. Unwelcome, it was not. After season 2 of Assassination Classroom ended on a sombre, but optimistic, note, this was definitely what manga readers and anime watchers, alike, received with open arms.

There is nothing exceptional in the stories told : they are merely slice-of-life episodes based on established characters' daily lives.
The animation and music is the same as previously seen, and ... the voice actors perform well as always.

Assassination Classroom: Extracurricular Lesson is an ONA with 8 episodes of 5 minutes that combined form 2 normal episodes of 20 minutes. The first normal episode (1-4) takes place between episode 1 and 2 of the second season of the main anime and the second normal episode (5-8) takes place in the middle of the 20th episode of the second season of the main anime. They're basically two extra episodes of comparable quality to the main anime.

The story for the first episode was surprisingly good and actually had an interesting and unexpected twist. The second episode doesn't have much of a story but is ... just some extra content.

The characters are the same as in the main anime however the focus in these two extra episodes is on some characters that had gotten a bit less attention so it has some nice character development.

The animation, sound and voice acting are all the same or on the same level as the main anime so it's of very similar quality.

Overall this ONA is nice to watch for just a bit of extra content. The quality is the same as the main anime and the character development adds to the main story. It's best to watch them in the correct context but watching them afterwards is fine too.

These eight short episodes filled the hole that was left as I finished watching the Ansatsu Kyoushitsu series.

Although it says 8, the main "plots" for these episodes are only two, so don't get your hopes up too much. But it still fulfills its duty for a normal day-to-day happening during the time of the assassination classroom. It's kind of like an alternate universe for some of the very violent animes/games, but these are actual canon and not just imaginary events.

I am very, very glad I decided to go out of my way to find these episodes.
Short but perfect.
